Abstract:
Many kinds of Indonesian woods have low treatability, such as those of Leguminosae which are hardly absorb wood preservatives. There are some ways to increase the treatability of woods, i.e. by using microorganisms, chemical and physical treatments. Increasing the treatability of woods by using fungi is better compared to using others, because fungi can degrade certain components of the woods selectively. A research had been done to increase treatability of woods of Albizia falcataria and Albizia chinensis. The research was carried out in a laboratory by using test blocks of the woods measuring 20 mm x 5 mm x 5 mm. The treatments were applying Aspergillus niger, Trichoderma viride, Chaetomium sp. and combination of the fungi. The results of the research showed that all of the treatments were significantly increase treatability of the woods.

Abstract:
The pulping and papermaking characteristics of three fast-growing hardwoods were studied. Moluccan sau (Albizia falcataria) had more than 50% pulp yields using the sulfate process. The pulp yields of 'bagras' (Eucalyptus deglupta) and 'kaatoan bangkal' (Anthocephalus chinensis) fall within the normal range obtained from other Philippine hardwoods studied. Good burst, tensile and folding strength and moderate tearing resistance were obtained from the pulp handsheets of the three species. Based on the chemical, morphological and strength properties, pulp yield and kappa number, these species can be classified as very good materials for pulp and paper using the sulfate process. A good pulp yield of 74.7% was obtained in 'kaatoan bangkal' using the neutral sulfite semichemical process (NSSC) with a chemical charge of 15% Na2S03 and 4% Na2C03. The experimental boards had slightly lower bursting strengths compared to grade-A linearboard. In commercial operation, long fibered pulp can be blended to hardwood pulp to improve the strength properties of the paper.

Journal of Tropical Forest Science 1 (3): 255 - 262 (1988)

Abstract:
Steamed wood fibres from some Malaysian woods were subjected to enzymatic hydrolysis. The yield of reducing sugar from fibres of rubberwood (Hevea brasiliensis) and fast-growing trees such as Acacia mangium, Paraserianthes falcataria and Gmelina arborea was under 20% of total fibre weight. On the other hand, fibres from oil palm stems showed a high yield of about 50% of the total fibre weight. Extraction of hemicellulose fraction with dilute alkaline solution improved the accessibility of enzyme for rubberwood but not for oil palm. Extraction by hot water increased slightly the saccharification of rubberwood and oil palm. With simultaneous enzymatic hydrolysis and fermentation of oil palm fibres, the glucose produced was rapidly consumed by yeast and converted to ethanol. The concentration of the ethanol reached a maximum of about 1% of the solution after three days reaction time and then decreased gradually.

Abstract:
Five fast-growing hardwoods, namely Eucalyptus deglupta (bagras), Endospermum peltatum (gubas), Anthocephalus chinensis (Kaatoan bangkal), Albizia falcataria (Moluccan sau), and Gmelina arborea (yemane) were pulped by kraft process using 15.6% sodium oxide (Na?O) with a sulfidity of 25.5%. Results showed that fast- growing species obtained yields ranging from 43.46% to 53.10%. Pulps bleached to a brightness using a three-stage CEH (Chlorination, Extraction, Hypochlorite) ranged from 83.3 to 87.1% GE. Among the pulps, 'Kaatoan bangkal' and 'yemane' had the best strength properties and 'bagras' the poorest.

A.1.2; No.4101-78-03.01.001; Management Information Systems Division (MISD); 110 p

Abstract:
A study was carried out on phenology and diameter growth of selected fast-growing tree species in Laguna, Nueva Vizcaya and Abra. Likewise, the annual magnitude and cycle of growth for each species were discussed. In Mt. Makiling, Laguna, relative humidity influenced the diameter growth of 'Kaatoan bangkal' (Anthocephalus chinensis), Moluccan sau (Albizia falcataria), 'gubas' (Endospermum peltatum), and 'yemane' (Gmelina arborea) followed by evaporation and sunshine duration. Rainfall, radiation and air temperature had the least influence factors mentioned affected 'ipil-ipil' (Leucaena leucocephala). Rainfall, evaporation and air temperature affected the growth of 'yemane' and 'Kaaton bangkal' in Diadi, Nueva Vizcaya. Phenological observations in all stations appeared to be timed considerably with weather. The flower bud, flower, and fruit of moluccan sau, 'bagras' (Eucalyptus deglupta), red gum (Eucalyptus camaldulensis) and 'yemane' developed during low rainfall, high solar radiation and sunshine duration. All species flushed and disseminated fruits/seeds before or during the rainy season.

Biomass production and root distribution of eight trees and their potential for hedgerow intercropping on an ultisol in Southern Sumatra


Hairiah, K; van Noordwijk, M; Santoso, B; Syekhfani, MS
Faculty of Agriculture; Brawijaya University; Malang; Indonesia

Agrivita 15 (1): 54-68 (1992)

Abstract:
Long term productivity of upland soils for food crops may be improved by using a 'hedgerow intercropping' or 'alley cropping' system. However, information on trees suitable for hedgerow intercropping on acid soils is scarce. Suitability of trees for hedgerow cropping depends on a number of above and below ground characteristics of the trees, such as pruning tolerance, biomass production, N-content of the prunings, decomposition rate of prunings, rooting depth, presence of horizontal branch roots, nodulation, mycorrhizal infection. Desirable tree characteristics further include the production of useful products such as firewood, browse for goats and/or edible pods. Trees which provide a sufficiently dense cover, when left unpruned, to shade out weeds may help to save labour. Pruning of trees affects their growth in many ways. Based on preliminary observations the hypothesis was formulated that a lower pruning height leads to more, but smaller branch roots originating from the stem base. In an experiment with five tree species this hypothesis was confirmed. Eight trees were evaluated for the characteristics mentioned on an acid soil; six relatively well known agroforestry trees: Leucaena leucocephala, Gliricidia sepium, Calliandra calothyrsus, Cassia siamea, Erythrina orientalis, Albizia falcataria, and two local tree species: Peronema canescens and Peltophorum pterocarpum. Averaged over the first three years of pruning, the highest biomass production and N-yield was found for Calliandra (12 Mg/ha and 360 kg/ha, respectively). Calliandra requires regular pruning, however, to avoid excessive shading of intercropped food crops. Over all, the best results in hedgerow intercropping on this acid soil may be expected from the relatively deep-rooted Peltophorum, or from alternating hedgerows of Gliricidia and Peltophorum, with a biomass of around 8 Mg/ha and an N-yield of about 200 kg/ha. Peltophorum forms the densest canopy in a small hedge volume when pruned in a 3-months cycle.

Abstract:
This paper reports the result of an experiment on the treatment of different forestry wastes, i.e. the sawdust of rubber (Hevea brasiliensis), Pinus merkusii, sengon (Paraserianthes falcataria) and the leaves of Melaleuca leucadendra with Schizophyllum commune for 7 weeks. The purpose of this study is to assess the effect of white-rot fungi inoculation to the decrease of chemical components like cellulose, lignin and hemicellulose. The results reveal that after 7 weeks treatment, sengon sawdust still has a very high cellulose content of 22.55%, in rubber tree sawdust lignin and hemicellulose contents are 32.66% and 47.39%, respectively. After the decrease of chemical components, lignocellulose waste could be fermented by solid state fermentation for biogas.

Utilization of cogon grrass land for timber estate
Pemanfaatan lahan alang-alang untuk hutan tanaman industri

Gintings, AN; Purwanto, Ign
Forest Research and Development Centre (FRDC), Bogor, Indonesia

Prosiding seminar lahan alang-alang [Proceedings of a Seminar on cogon grrass Land], Bogor, September 1992; Sukmana, S et al. (eds.); Bogor, Pusat Penelitian Tanah dan Agroklimat, 1993; p 137-147

Abstract:
Total area of critical lands in Indonesia is about 13.2 million ha, of which about 5.9 millions ha are in the forest area and 7.3 million ha outside forest area. The widespread of critical lands are mainly caused by shifting cultivation activities and forest fires. These activities usually made the lands become more critical, indicated by the domination of cogon grass (Imperata cylindrica) vegetation. The establishment of timber estate (HTI) programmes by the government of Indonesia was expected to reduce the widespread of critical lands. This assumption was based on the rule that the lands to be used for timber estate are critical lands inside the unproductive production forest areas which are usually found as cogon grass land, bush fallow lands, and sparsely stand forests. Forest tree species that are feasible to be grown on cogon grass lands are: Paraserianthes falcataria, Gmelina arborea, Cassia siamea, Fagraea fragrans, Macadamia sp., Acacia mangium, Peronema canescens, Pinus merkusii, Schima bancana, and Swietenia macrophylla. Basically, implementation of the timber estate activities considers 3 aspects, namely: usefulness, sustainability of land resources and business. Therefore, the success of timber estate programmes would have positive impacts on: water regime of adjacent areas, improvement of micro-climates, soil fertility maintenance, soil erosion and flood control. Besides, the most important roles of timber estate in the future are: the use of lands that are currently often less useful for agriculture, provide new employments, create flexible natural resource development, and serve as a development agent for isolated areas.

Kesesuaian jenis pohon dengan kondisi lapang di Sentani, Irian Jaya

Hendromono; Wilaida, T; Mutiara, T; Sutisna, U
Paratropika 2 (2): 26-39 (1994)

Abstract:
Sentani hill area and the surroundings in Irian Jaya is one of barren areas in Indonesia due to erosion in wet seasons and fires in dry seasons. Reforestation and afforestation are alternatives to improve the ecosystem in this area. A research was conducted to select suitable species for this area and to recommend the next silvicultural actions. A fieldwork was conducted by ground survey and collecting secondary data. The primary data needed were physical and chemical properties of soil, slope, altitude, flora, pests and diseases. The secondary data needed were annual rainfall, number of wet and dry months, relative humidity, ambient temperature, maximum and minimum temperatures. The results showed that the most parts of the area were lacking of nutrients in varying degrees. The promising species for reforestation in the area were Acacia mangium, Anthocephalus chinensis, Calliandra calothyrsus, Cassia siamea, Gliricidia sepium, Intsia bijuga, Octomeles sumatrana, Paraserianthes falcataria, Pterocarpus indicus and Samanea saman. The species recommended for afforestation were Aleurites moluccana, Anacardium occidentale, Artocarpus altilis, Artocarpus heterophyllus, Gnetum gnemon, Parkia speciosa and Pometia pinnata. Planting stocks for reforestation and afforestation should be of high quality and they should be planted at the beginning of the wet season. Plant protection from fire, pests and diseases should be done intensively.

Suhartati; Lempang, M
Jurnal Penelitian Kehutanan [Forestry Research Journal] 9 (2): 36-43 (1995)

Abstract:
An experiment was conducted using sugarcane bagasse, a waste of sugarcane mills, as a medium to grow tree seedlings in a nursery. The cane bagasse was composted in three ways, namely natural, accelerated and artificial. Seedlings of four tree species including Calliandra calothyrsus, Cassia fistula, Paraserianthes falcataria, and Vitex cofassus were used in this experiment. Although all treatments gave no significant difference on height and diameter increments of the seedlings, however, cane bagasse could be used as a medium to raise tree seedlings. Accelerated compost of cane bagasse gave somewhat higher fresh weight and ovendried weight of the seedlings.

Abstract:
Dumping off disease was found on Abrus precatorius, a medicinal plant, in Cimanggu, West Java. In relation to the occurrence of the disease, a research had been conducted to determine the symptoms and identify the causal agent of the disease, as well as to study the character of the pathogen. The results of inoculation test showed that only Rhizoctonia solani was able to infect the plant and produced disease symptoms similar to those found in the field and the fungus was also able to infect Caesalpinia pulcherrima, Paraserianthes falcataria, Glycine max and Abrus precatorius itself. However, no symptoms appeared when the fungus was inoculated to Leucaena leucocephala.

Buletin Kebun Raya Indonesia [Indonesian Botanic Garden Bulletin] 8 (1): 16-24 (1994)

Abstract:
Observation on natural regeneration ability of the Bogor Botanical Garden living collections were conducted. There were about 100 soil samples taken from 25 main plots; each plot was divided into 4 subplots of 20 cm x 20 cm x 10 cm to determine the survival ability of falling seeds in the Botanical Garden condition. The results showed that only 100 species survived, consisting of trees, shrubs and herbs. Although the soil samples were taken from the tree collection areas, the number of tree seedlings found waslower than that of herb seedlings. Observation on the germination ability of the seed already fallen or lying on the ground surface showed lower germination result than that of the fresh one taken directly from mature fruits that were still intact on the trees. Natural regeneration of living collection can be increased by harvest and post harvest management.

Abstract:
Six species of reboisation trees were commonly used in the Downstreem Watershed of Ciapus, Cisadane, namely: Artocarpus altilis, Artocarpus heterophylla, Gnetum gnemon, Paraserianthes falcataria, Parkia speciosa and Pterocarpus indicus. A completely randomized experiments were carried out to investigate the effects of adding different initial media on the growth of those trees. Four treatments were applied, i.e. soil, soil + compost, green manure + soil, and the control. The result showed that the addition of green manure and soil could support better vegetative growth up to ten month observation, compared to the other treatments. Meanwhile, the addition of soil could result in the high growth rate, of about 65%. It was concluded that the addition of such initial media could be an alternative way to induce the growth of those important trees.

Abstract:
Alley cropping is considered as an agriculturally sustainable soil and crop management strategy. This 4.5 year-old study provides some insight into the sustainability of a low-input alley cropping system on a low base status, high aluminium saturated soil of the humid tropics. Calliandra calothyrsus, Paraserianthes falcataria, and Gliricidia sepium were grown in 4 m wide alleys at three lime levels, along with a no tree as control. An upland rice-cowpea-fallow cropping pattern has been applied through five cycles. A total of 175 kg/ha N, 120 kg/ha P, and 175 kg/ha K were applied during the first 52 months of the trial. Twenty-five kg/ha N, 40 kg/ha P, 75 kg/ha K, and 20 kg/ha Mg were applied in April 1989 prior to the tenth crop (cowpea). In general, both rice and cowpea yields decreased drastically over time. Paraserianthes was most effective in improving crop yield over no tree plots for the first 4 cropping cycles. The higher fertilization dosage applied in April 1989, reversed the trends of decreasing food crop yields. Calliandra was the most tolerant species under the alley cropping management system. Tree mortality was about 3% and biomass production was the greatest for the three tree species. A higher dosage of fertilizers than applied during the first 52 months is needed to develop a sustainable alley cropping system on this soil. A balance between tree pruning management and fertilization practices must also be determined.

Effectiveness of shrubs and agroforestry in the Kadipaten village (Citanduy sub-watershed) in decreasing run-off and erosion
Efektivitas semak dan agroforestry di Desa Kadipaten (Sub DAS Citanduy) dalam memperkecil aliran permukaan dan erosi

Anwar, C; Baheramsyah, K; Hamzah, Z
Buletin Penelitian Hutan [Forest Research Bulletin] (569): 1-8 (1995)

Abstract:
Native plant cover normally provides good run-off and erosion control. Trees, undergrowth and grasses contribute to this protection by which nature limits soil loss. A research was conducted to offer information to decision makers on suitable plant cover mixtures and cropping systems capable of reducing run-off and erosion on latosolic lands with slopes up to 30%. The research was aimed at evaluation of the anti-erosion influence of agroforestry and shrubs. Calculations of run-off and soil loss were based on measurements made on 0.38 ha of land that was cropped for 2 years under the agroforestry system and four plots of 4 m x 22 m vegetated with shrubs. The agroforestry crops included Psidium guajava, Annona squamosa, Swietenia macrophylla, Paraserianthes falcataria, Parkia speciosa, Artocarpus integer, Elettaria cardamomum, Chloris gayana, Panicum maximum, Leucaena leucocephala and Maesopsis eminii. Run-off water and removed soil during individual storms were caught in receiving drums for six months. The result of the observations showed that shrubs were more effective in halting run-off and erosion than the agroforestry system. Run-off and erosion under agroforestry crops were 0.31% and 0.061 t/ha/year, while the figures for shrubs were respectively 0.21% and 0 t/ha/year. Eventhough soil was eroded off agroforestry lands, yet the system was considered satisfactory to conrol erosion because the annual soil loss is still considerably less than the maximum tolerable dosage (10-12.5 t/ha/year). The protective effects and the capability of agroforestry to preserve productivity of the soil are evident.

Rimba Indonesia [Indonesian Jungle] 30 (1-2): 2-8 (1995)

Abstract:
The reforestation and tropical forest management project (ATA-267) has worked on the problems of cogon grass (Imperata cylindrica) lands in the afforestation Riam Kiwa area, South Kalimantan since 1986. So far more than 100 species have been included into species trials. Acacia species have performed well in the difficult afforestation conditions, and particularly Acacia mangium has proved to be a reliable and well-growing afforestation species. Acacia crassicarpa has also performed very well, and is now under detailed testing. Two other acacias, Acacia aulacocarpa and Acacia auriculiformis, may also be useful species. Gmelina arborea has grown very well on fertile soils. Fire resistant, ability to suppress grasses and good wood properties make the species an interesting alternative. Paraserianthes (Albizia) falcataria has grown well on fertile sites only. Furthermore, it is not effective in suppression of the grass because of the thin canopy. Eucalypts have performed poorly in the field trials. The survival of most species has been low, and growth rate as well as shading properties poor. The poor survival and growth of Pinus species during the first years after planting needs further studies. The tested local pioneer species have mostly failed or been too slow-growing for grass suppression. Peronema canescens, a local substitute to teak, has been the most promising local species and can be easy propagated vegetatively. Growing shade tolerant species (Shorea sp., Dipterocarpus sp.) has proved to be difficult on grassland. Even under the shade of fast growing species mortality has been high during the long dry seasons. Several species can be successfully used in the afforestation of grassland. The final selection depends on the soil variation and the objectives of the activity. For various reasons use of more than one species is recommended. In the beginning of any new reforestation/afforestation project, the applicability of the results of Riam Kiwa should be tested with small field trials.

Abstract:
Three timber species, i.e. pine (Pinus merkusii), rubber (Hevea brasiliensis) and sengon (Paraserianthes falcataria) were treated with two boron preservatives using cold soaking method. The two preservatives used were 5% borax and 10% the mixture of borax and boric acid. The soaking periods were 1, 3, 5 and 7 days. Forty timber samples with 5 x 5 x 50 cm of size were used for each species and each treatment. The average moisture content of the samples of each species were 29.9%, 31.9% and 30.3%, respectively. The results showed that two species, i.e. pine and rubber achieved the minimum standard on preservative retention. The minimum retention required for borax preservative was 8.7 kg/m3, whereas for the mixture of borax and boric acid was 8.4 kg/m3. The required minimum penetration for both preservatives is 10 mm. The study recommended that pine should be treated in 5 days using borax preservative or 1 day using the mixture of borax and boric, both with cold soaking method. The treatment for rubberwood is recommended to use the mixture of borax and boric acid for 3 days. (Revised author's abstract)

Priasukmana, S
Forest Research Institute; Samarinda, East Kalimantan, Indonesia

Proceedings of the Fourth Round-Table Conference on Dipterocarps, Bogor, Indonesia, 12-15 December 1989; Soerianegara, I et al. (eds); Bogor, SEAMEO BIOTROP, 1991; BIOTROP Special Publication 41: 417-423 (1991)

Abstract:
Some planting experiments of dipterocarp species were carried out by the Forest Research Institute (FRI) Samarinda in the area damaged by fire and that of industrial forest plantation or 'timber estate'. Enrichment planting with strip-line system was applied in the area damaged by fire, while in the timber estate mixed planting with fast-growing species was used. Two years after planting, the survival rate of Shorea species was low in the area damaged by fire and a little better in the timber estate, while Dryobalanops was better than Shorea sp. This result also showed that Shorea polyandra, Shorea johorensis, Shorea smithiana and Shorea oleosa grew better than the other Shorea species. In these experiments, dipterocarps which are growing under Leucaena leucocephala or Paraserianthes falcataria grew better than those under Eucalyptus and Anthocephalus chinensis. The experiment of planting dipterocarps under rubber trees showed a promising prospect. The problem of mixed planting of dipterocarps with fast-growing species and rubber trees will arise when the time comes to extract the fast-growing species, if the planting space was not designed properly.

Prosiding Pertemuan Ilmiah Tahunan: Peranan Mikrobiologi Dalam Industri Pangan [Proceedings of Annual Scientific Meeting; Roles of Microbiology in Food Industry], 10 Desember 1994; p 338-342

Abstract:
Five species of mushrooms i.e. Lentinus edodes, Pleurotus cystidiosus, Pleurotus flabellatus, Pleurotus ostreatus and Pleurotus sajor-caju are edible white rotting fungi. In a study those mushrooms were cultivated on sawdust substrate of jeunjing (Paraserianthes falcataria), rubberwood (Hevea brasiliensis), kemiri (Aleurites moluccana), mahoni (Swietenia macrophylla) and pulai (Alstonia scholaris) which were mixed with 10% of rice bran and 5% of lamtoro gung (Leucaena leucocephala) leaves and distilled water. Biological conversion efficiency (BE) was measured based on the percentage of the fresh weight of fruit bodies obtained from the weight of dried substrate. The result showed that the highest weight was found from Pleurotus ostreatus on kemiri, whereas the lowest was from Pleurotus on mahoni sawdust substrates. The highest BE values were found from Pleurotus flabellatus (50.56%), Pleurotus ostreatus (57.97%), and Pleurotus sajor-caju (51.80%), and the lowest was from Pleurotus cystidiosus. Substrates from rubberwood, kemiri and pulai were easier converted by white rotting fungi with the BE values 63.15%, 66.30% and 62.03%, respectively, rather than the mahoni's substrates by the BE of 6.32%.

Biological and environmental pest and disease control strategy in PICOP


Anino, EO
Forest Research and Technical Assistance Services, Paper Industries Corporation of the Philippines (PICOP); Tabon, Bislig, Surigao del Sur, Philippines

BIOTROP Special Publication 53: 83-84 (1994)

Abstract:
Non-use poisonous and costly pesticides in PICOP has compelled its researchers to explore ways and means of utilizing natural enemies as biological agents and harnessing the force of nature to control pest and disease organisms or factors that threatened, in one way or another, its extensive plantations. Varicose borer (Agrilus sexsignatus), the most important insect pest of Eucalyptus deglupta (bagras), has been attacked by an unidentified species of egg parasite. Since they cannot be cultured in the laboratory using other hosts, multiplication of this natural enemy in the field was enhanced by providing them varicose borer eggs by flaking the barks of susceptible bagras trees to encourage the varicose borer to aviposit on flaked points. The fungus Corticium salmonicolor, causing cancer disease in Paraserianthes falcataria (falcata), and Acacia mangium were observed to have been parasitized by Trichoderma sp. Trichoderma sp. reduces or stops the development of cancer lesions. Experimental release was conducted in plantation sites sparsely populated with the hyperparasite to augment its population. Combined effects of hyperparasitism and other environmental factors could have brought down cancer incidence and severity to insignificant level. Trichoderma sp. has also been proved in an experiment to have reduced the incidence of root rot disease in Pinus caribaea seedlings caused by Fusarium solani. The devastating effects of needle blight caused by Cercospora pini-densiflorae on Pinus caribaea were minimized by enhancing the vigour of the seedlings through the application of mycorrhizal fungi Pisolithus tinctorius and Scleroderma sp. Non-mycorrhizal pines failed to resist the disease and died out. Grubs of June beetle (Leucopholis irrorata) fed and killed the roots of falcata in some parts of the plantations. The insect pest was controlled by introducing cultures of the antagonistic fungus Metarrhizium anisopliae onto the rhizosphere of falcata plantings. Rust disease, caused by Uromycladium tepperianum, which severely hit the falcata plantations of PICOP has been put under control by augmenting the population of fungal hyperparasite Penicilium italicum in addition to Acremonium recefei and the suspected Tuberculina sp. Moreover, the rust fungus does not multiply fast in sites with high temperature but thrives well in sites with low temperature, thus falcata has no longer been planted at elevations over 250 m above sea level where climatic conditions favour the fingus. Combined effects of these biological and environmental control methods have reduced the effects of rust disease to insignificant level. Uoko vine (Mikania scandens) was the most problematic weed species in PICOP's plantation. Weeding operation of free young stands from the strangling Uoko vines constitutes large part of maintenance cost. Recently, the growth of the weed has been stunted by the combined effects of suspected viral little leaf disease associated with aphid feeding and by a hemipterous sap-sucking insect which kills the young leaves and breaks the tender vines. The disease vector and the insect pest are currently dispersed into the plantations. Eucalyptus urophylla and Eucalyptus hybrids are affected by leaf blight caused by extreme heat during dry days and wilt temperature fluctuations during winter months of December, January and Forest Pest and Disease Management.

Anatomical structure of Philippine trees in relation to the occurrence of wooliness or fuzziness in veneer manufacture


Alonzo, DS; Lopez, FR; Valmonte, AD
FORPRIDE (Forest Products Research and Industries Development) Digest 5: 22-40 (1976)

Abstract:
The occurrence of wooliness of the surfaces of lumbang veneer was studied based on the structure of the wood. The characteristic wooliness of the veneers cut is associated with the presence of tension wood. The fibers in tension wood show the presence of an unlignified layer called the gelatinous layer (G-Layer). The specific gravity of tension wood is higher than normal wood from the pith and to the bark. However, the pattern of variation is similar in both normal and tension woods. Irrecoverable collapse and high longitudinal shrinkage were exhibited by veneers with wooly surfaces. This is attributed to the absence of incrusting substances between the microfibrils, resulting in the formation of strong hydrogen bonds. Moreover, the highly crystalline nature of the cellulose in tension wood, together with the effect of S1 layer contributed to its higher longitudinal shrinkage.

Leaf protein from hardwood species as feed supplement for chickens


Gonzales, EV
Forest Products Research and Development Institute (FPRDI) Journal 8 (1): 66-76 (1984)

Abstract:
Of the eight leaf species analyzed for protein content, katurai (Sesbania grandifora) gave the highest protein content of 29.58% followed by Mollucan sau (Paraserianthes falcataria, synonym: Albizia falcataria) with 26.14%. The leaves of these two species were used in the experimental feeding of chicken to evaluate the nutritional value of the leaf proteins. Katurai and Mollucan sau leaf meal, in separate feeding trials, were incorporated as protein source with or without fish meal in the basic diet of experimental chickens. The control diet consisted of 15% fish meal. In addition to the basic ingredients, the three experimental diets had 3.75%, 11.25% and 15% of either katurai or Mollucan sau leaf meal. The fed efficiency of the leaf meal was determined by the amount of feed consumed and the weight of the chicken. Statistical analysis showed that the gains in weight of chicken fed with 3.75% and 11.75% katurai leaf meals were not significantly different from those rationed with the control diet of 15% fish meal. The feed efficiencies of the diets at these two levels of leaf meal were better or just as good as the control. With Mollucan sau, only the diet with 3.75% leaf meal was not significantly different from the control. However, the feed efficiency of this diet was not comparable to the control. The results of the experimental study showed that katurai leaves can be used as a feed supplemented to the basic diet of chicken in levels of 3.75-11.25% as substitute for the conventional fish meal. Mollucan sau leaves can be used up to a level of 3.75%.

Abstract:
The impact of large-scale forest clearing on soil physical properties for planting of fast-growing timber species at Kemasul Forest Reserve was investigated by collecting 7.6 cm diameter soil core samples to a depth of 10 cm in plots established in secondary forest, cleared area (with completely no vegetation) and Acacia mangium plantations of 4 and 6-year old. It was found that clearing secondary forest significantly (p = 0.05) increased bulk density, soil temperature and decreased soil moisture content, total porosity, aeration porosity, water retention and available water holding capacity (AWC) in all sampled areas. Almost 75% of the entire study area was still heavily compacted (bulk density 1.20 g / cubic cm) after four to six years or more after initial clearing. Recovery from compaction has only occurred in the cleared area when abandoned for secondary succession. This information can be used to assist forest managers in selecting sites suitable for planting of fast-growing timber species and appropriate site management techniques after forest clearing.

Abstract:
Heterogeneity of climate, terrain, hydrology and soil, and rapid social and cultural changes condition land and forest use in Sarawak. Processes in the natural and cultural ecosystems are fuzzy and largely unpredictable, including the attitudes of society and individuals toward the forests. Sustainability of conservation and management of the national Permanent Forest Estate (PFE) requires integrated, holistic approaches to forestry development within regional and national development. Sustainability within forest management units requires comprehensive, integrated and reliable data bases and flexible, biocybernetically designed management strategies to cope with the risks and uncertainties attached to all options. Examples are given to illustrate some crucial issues and critical areas of uncertainty. Options and strategies for integrated research and management which are likely to be the least wrong in a word of uncertainty, change and conflict, are indicated. Political strategies must allocate responsibilities realistically and effectively. Management strategies towards sustainability must coordinate and integrate scientific and application-oriented research, and forest conservation and management, jointly by the various forest users and the government.

Abstract:
A large-scale plantation forest of fast-growing tree species has been implemented in Kalimantan and Sumatra since late 1980s. Most forestry companies related to the industrial forest plantations are now conducting tree improvement to improve productivity and quality of plantations. A bilateral technical cooperation (Japan-Indonesia) project for forest tree improvement commenced in 1992. Up to date the project has established the trials of 75 seed sources of 1st and 2nd generation of Acacia mangium, Acacia crassicarpa, Acacia auriculiformis, Eucalyptus pellita, Eucalyptus urophylla and Paraserianthes falcataria in 7 provinces by collaborative research activities with six private forestry sectors in Sumatra and Kalimantan as a major role in technical cooperation. A collaborative work between the project and the private forestry companies was integrated as the Indonesian Tree Improvement Network in 2002. On the occasion of the termination of the project at the end of November 2002, this paper describes the ongoing and future collaborative research activities on forest tree improvement for plantation forests and the self-sustainability of the Centre for Forest Biotechnology and Tree Improvement.

Abstract:
Isozyme markers have been used to identify potential characters in sengon (Paraserianthes falcataria), rattan (Calamus manan) and tengkawang tungkul (Shorea stenoptera). Three to six enzyme systems were employed to obtain specific bands related to superior growth and resistance to insect in rattan manau, tengkawang tungkul and sengon, respectively. Growth characters, namely height and diameter, were observed in tengkawang tungkul and the presence of an uncommon organ called vestigate was observed in rattan manau which could also be identified by specific banding patterns. The same phenomenon was also noted in sengon which seems to have a higher degree of resistance to stem borer. Applying this technique with more number of markers to the identified parents and their progeny in the future would enhance the breeding of those forest species by providing genetic map of the desired traits.

The results of RAPD analysis indicated that genetic diversity among Java provenances showed a variation. It showed that Java provenances were genetically similar to one of the Papua provenances (Biak) and different from the other Papua (Wamena) and the Maluku (Halmahera) provenances. This suggests that Java provenances are genetically close to Biak provenance. (Authors' abstract)

Abstract:
Wood demand for construction, pulp or paper and energy industries is expected to increase to 150 million m3/ year by the year 2010. The present production of the natural and production forests vary from 23.9 to 61.6 million m3/ year (Saleh et al 1990). To meet the projected demand, the Government of Indonesia through the Ministry of Forestry has increased the establishment of plantation forests (HTI). The species established in the plantation forests include local and exotic species such as Tectona grandis, Pinus merkusii, Acacia spp., Eucalyptus spp., Dalbergia latifolia, Paraserianthes falcataria, Swietenia macrophylla, and Shorea spp. Most of the plantation forests has been established as monocultures or single species and the consequence is that some pests and diseases appeared thus needing attention for early prevention.|A survey was made on plantation forests in several big islands of Indonesia such as Sumatra, Kalimantan and Java. Observations were made on the presence of pests and diseases. Reference specimens were collected and microscopically examined in the laboratory. Insect pests were identified by Textbook of Insect Identification and fungi were cultured, identified and detailed photographic records compiled. Field observations were made from 1996 to 2002 in nurseries, young and mature plantations. There are 6 families of Lepidoptera, 1 Hymenoptera, 3 Isoptera, 4 Coleoptera, 1 Orthoptera, 2 Homoptera, and 4 families of Hemiptera that were found as plantation forest pests belonging to sap-sucking insects, branch or stem borers, leaf skeletonizing insects, root collar and lower part of stem insects, leaf eating insects, and 16 species of fungi that were found as the agents of plantation forest diseases (damping-off, wilt diseases, root-rot diseases, mildew, stem cankers, etc). Forest pests and diseases usually attack fruits/ seeds, leaves, stems, and roots are listed. (Modified authors' abstract)

Pertanika 9(1): 81-87(1986)

Abstract:
Acacia mangium one of the main species used for forest plantations as well as reforestation in Malaysia has been has been selected on account of its rapid growth and ability to overcome competition from weeds. A 4.5 year-old plantation stand in Sarawak had a density of 1084 trees/ha and a top height of over 20 m. The dbh of the trees ranged from 4.3 cm to 24.2 cm and averaged 14.3 cm. Regression of ranch, stem and total above- ground biomass on d b h produced equations with correlation coefficients 0.95. The biomass of the stand was estimated at 82. 1 tonnes/ha. The mean annual 18.2 t/ha is comparable to those of intensively managed crops such as Eucalyptus nitens and rubber. Several sample trees had stained heartwood and soft pulpy cores and further studies are recommended.

Abstract:
Distance of planting had dramatic effects on the diameter and height growth of the nitrogen fixing tree species grown under trial. Generally, the wider the spacing, the shorter the trees but the bigger their diameter. Paraserianthes falcataria trees spaced at 1m x 0.5 m grew very tall compared to other spacings. The growth pattern of all the species was observed at each time of measurement not to have followed the biological curve due to stem breakage and other damages caused by typhoons which passed over the experimental site.

Fast growing hardwood plantations on logged over forest sities in Sabah

Tan, KC; Jones, N
Malaysian Forester 45(4): 558-575(1982)

Abstract:
Fast growing tree plantations have an important part to play in the future development and management of the timber industry in Sabah. These plantations can supply large quantities of uniform wood from a relatively small land area thereby reducing the overall pressure on the natural forest. The timber produced from the fast growing tree plantations can be used for pulp and paper or mechanically processed into wood products. Yields from 3 fast growing hardwoods, A.falcataria,E.deglupta and G. arborea are cited in terms of mean growth influenced by some site factors. The wood qualities of these species are described and as assessment has been made on their economic ratations under Sabah Softwoods conditions. There is great potential for the improvement of the quality of wood grown as well as the increasing of wood volumes produced on the same land area,through active tree improvement programmes.

Pests and diseases of forest plantation trees with special reference to SAFODA


Khamis, S
8th Malaysian Forestry Conference; andakan; Sabah; 1982

Abstract:
The paper describes the diseases of acacia mangium, Pinus caribaea, P. oocarpa, Gmelina arborea, Eucalyptus deglupta and Albizia falcataria. Acacia mangium is attached in Imperata grasslands by rodents (Rattus argentiventer). Slug attack (Vaginula sp.) is reported from peaty plantation sites. Caterpillars of the butterfly Eurema blanda defoliate the mimosa like leaflets of young Acacia mangium seedlings. Sometimes the damage is so severe, that the stem is completely cut off resulting in death of the seedling. Grasshoppers usually are present in various numbers in nurseries causing only minor damage. In plantations, Acacia mangium can be attacked by squirrels which strip off the bark at the base of the tree resulting in decay of the exposed wood. Termites are destructors which have to be taken seriously. In 1981, it was found that 23% of the 10-year old plantation trees in Ulu Ukit were infested. Attack by Ambrosia beetles (pinbole borers) of the family of Scolytidae and Platipodidae is frequently observed and symptoms are recognizable from the dark staining around the holes. Attack is seldom severe. Out of the diseases in the seedling stage damping off caused by fungi (Phytophtora, Pythium, Fusarium, Rhizoctonia) can be a very serious problum in the nursery. Charcoal root disease is another disease of the nursery and is caused by Macrophomia sp.. Dieback is found on A. mangium trees that are growing on poor soil. A sungus Tremetes corrugata is associated with the disease. Pin disease caused by the fungus Corticium salmonicolor is the most serious plantation pest of Acacia mangium. The fungus kills the bark, so that when the bark flakes off the wood underneath is exposed and eventually will decay.

Fertilizer effects on the tree growth and some wood properties of Paraserianthes falcataria on Durina Series Soil


Wan Rasidah, WAK; Ani, S
Forest Research Institute Malaysia (FRIM); Kepong; Selangor

Journal of Tropical Forest Sciences 4 (4); 303-309 (1992)

Abstract:
Nitrogen and phosphorus combinations were applied on young seedlings of Paraserianthes falcataria (three months after transplanting) at six-monthly intervals until the seedlings were 21 months old. Diameter growth, total height increment, mortality rate and heartwood to sapwood (HS) ratio were found to be insignificant at all levels of treatment. Specific gravity was found to be highly significant between fertilizer treatment and between discs. N2P1 was significantly different from the rest of the treatment, whereas N2P0 was only significantly different from NIP1. Nitrogen application in combination with P appeared to have some effects in increasing the specific gravity in comparison with nitrogen in the absence of P. There was a significant difference in specific gravity between the three discs where the highest value was 0.39 and the lowest was 0.27. No significant interaction was observed between portions of disc and fertilizer treatment.

Properties of particleboards manufactured from fast-growing plantations species


Razali, AK; Kuo, HS
Faculty of Forestry, Universiti Putra Malaysia; 43400 Serdang, Selangor, Malaysia

The Malaysian Forester 52 (1): 8-14 (1989)

Abstract:
The main objective of the study was to determine the suit ability of converting first thinning wood material into parti cleboards by testing their physical and mechanical properties. The first thinnings (4-5 year old) of fast-growing hardwood forest plantation species, Acacia mangium, Gmelina arborea and Paraserianthes falcataria were used as the raw wood material for the manufacture of medium-density particleboards. In addition, thinnings of Araucaria hunstenii, a softwood species, were also used. Wood flakes of each test species were fabricated into 650kg/m3 density boards with 7% and 1 % resin and wax contents, respectively. Commercially available urea formaldehyde resin adhesive was used as the binder. A. mangium and G. arborea flakes were also blended at a 7:3 ratio to produce mixed species boards. The properties tested were in with the Japanese Stan dards, JIS A 5908-1983. All the 650 kg/m3 boards manufactured met the requirement of JIS Type 200 board. Among the hardwood species, G. arborea had the highest bending strength (MOR) at 281 kg/cm2 and internal bond (IB) strength at 10 kg/cm2. A mangium on the other hand, had the highest stiffness (MOE) at 3.4 x 10 4kg/cm2 and screw retaining force at 116.2 kg, with lowest water absorption (16.2%) and thickness swelling (15.4%) properties. A. hunstenii boards had the highest MOR (302 kg/cm2) and MOE (3.8 x 10 kg/cm2), but lowest IB at 7 kg/cm2 compared to all the other 650 kg/m3 particleboards. P. falcataria particle board manufactured at a density of 500 kg/m3, satisfied only JIS Type 100 board properties: MOR 135 kg/cm2, MOE 1.5 x 10 4 kg/cm2 and IB 4 kg/ cm2. The first thinnings of the fast-growing plan tation species were successfully manufactured into interior grade particleboards using readily available synthetic resin adhesive. This provides an opportunity to utilize the fibre resources which otherwise would be left unused in the plantation forest.

The Malaysian Forester 53(4): 82-90(1990)

Abstract:
The intergrity durability of phenol-resorcinol formaldehyde (PRF) and urea formaldehyde (UF) glue joints on three fast-growing tropical hardwood species were evaluated. Single and mixed species laminations were produced using these adhesives at room temperature. The intergrity of glue bond to delamination was tested according to the ASTM D 1101-59 (76). All species glued with PRF glue offered less than 1% of the maximum allowable 10% delamination percentage while all the UF glued species combinations experienced more than 10% delamination percentage. PRF glue joints was found to be stronger and more durable than UF glue joints. Mixed-species combination of PRF glue joints performed better than their single-species counterparts.

Abstract:
The objective of this paper is to present the practical experiences of Sabah Softwoods in forest tree plantations. In order to succesfully establish a forest plantation, apart from having sufficient initial capital and commitment one has to have good knowledge in its utilisation and of course, the future market potential. Equally important is the planting of genetically improved material and silvicultural inputs to enhance production and profitablity. Inevitably, like other investments there are always constraints and limitations which require appropriate assistance and consideration from the government.

Proceedings of A Regional Symposium on Recent Development In Tree Plantations Of Humid/Subhumid Tropics of Asia;5-9 June 1989;Universiti Pertanian Malaysia;Selangor;p809-820

Abstract:
Five plantation species namely Acacia mangium, Gmelina arborea (Yamane), Paraserianthes falcataria (Batai), Hevea brasiliensis (Rubberwood) and Elaeis guineesis (oil palm) were selected for caloric content study. Calorific values of these species were determined using Laboratory Oxygen Bomb Calorimeter. The experiments were carried out at equilibrium moisture content (EMC) and at oven dry condition. The wood samples were chipped, ground and pressed into pellet form. They were room temperature to reach EMC. Two sets of wood samples were prepared; extracted and unextracted samples. Results show that at oven dry condition, Gmelina arborea exhibited the highest calorific value of 4741 cal/g followed by Acacia mangium,4734 cal/g, and Hevea brasiliensis, 4271 cal/g. At EMC condition the calorific values of these species were significantly lower than at the oven dry condition. The unextracted samples exhibited higher calorific values compared to the extracted samples. The study also showed that the calorific values of these species were greatly influenced by moisture content, extractive content and, to a certain extent, the density. The density of wood was found to be an important factor influencing the period of combustion. Although these woods have lower calorific values compared to other commonly used fuel e.g., petroleum, it offers the most attractive alternative as the source for energy. The fact that wood is a renewable material and is available in abundance makes it prudent to consider wood as a supplement for energy resource.

Proceedings;International Workshop on Albizia and Paraserianthes Species;Bislig, Surigao del Sur, Philippines: 13-19 November 1994;Forest,Farm and Community Tree Research Reports;1997;pp. 151-156

Abstract:
Genetic variation in Paraserianthes falcataria is believed to be high in the natural sites. In plantation in Java, the genetic variation proved to be very low, and this condition limits the use of this species for breeding progrmas. However, the very broad range of provenances and their environmental characteristics give a promising future that by a sound and coordinated breeding program, improvement on any trait can be achieved. Additionally, supporting research could result in a sound tree breeding program.

Proceedings;International Workshop on Albizia and Paraserianthes Species;Bislig, Surigao del Sur, Philippines: 13-19 November 1994;Forest,Farm and Community Tree Research Reports;1997;pp. 140-144

Abstract:
Of the 100 Albizia species distributed in the tropics, about 16 species are indigenous to the Indo-Burma region. The data available for nine species shows that majority of the species have medium-density timber with a mean yield air dry specific gravity (SG) ranging from 0.55 to 0.67, although A. mara has rather heavy wood (SG 0.87) and A. stipulata has light wood (SG 0.42). Despite the fact that the timber shows a great range of variation in color, weight, and texture among the species, specimens of different species often integrate in color and show striking similarity in wood anatomical features, which makes separation of species impracticable. The heartwood is brown to dark brown in many species, while light brown heartwood is characteristic of species like A. mara and A. stipulata. Although A. lebbeck is a well known timber in the trade as a substitute for walnut, a good supply of construction timber is from species like A. odoratissima and A. procera.

Abstract:
P. falcataria (L.) Nielsen (falcata) is one of the most favored plantation species of PICOP Resources, Incorporated, this species is now the main raw material for pulp and paper-making, aside from being a major dollar earner as log export. Timber product utilization, however, has been limited to blackboard production either as raw blackboard or a plywood with veneer overlays. More products are being developed using its pulp. With the multiplicity of products that can be derived from falcata, PICOP has embarked on extensive falcata plantation establishment which reached as high as 16,959 ha in its concession. And although its agroforestry program, private tree farmers have an assessed planted area totalling arpund 6,000 ha. PICOP's success in falcata plantation establishment and product development has been the result of years of research and development.

Abstract:
Seven provenances of Paraserianthes falcataria (L.) Nielsen were studied to identify the provenance with the best genetic potential in terms of growth, volume per hectare, survival, bole form and resistance to insect pests and diseases on the 11th year after outplanting. Height and diameter growth of the falcata provenances were found significantly different in two locations Rds 72-2 and 5A4, non-significant differences in performance among the provenances occurred only at the Rd2 location, Solomon falcata from kalabangara Island (Solomon Island attained significantly different superior height and diameter growth compared to other six provenances at Rd 72-2 and at Rd 5A3 except Tabibuga Papua New Guinea (PNG). The survival data showed non-significant differences in three locations. In terms of volume yield (m3/plot), Solomon falcata attained the highest yield which differed significantly with other six provenances at Rd 72-2. Said provenance attained results that are not significantly different with other provenances, only at Rd 5A3 except for Ivory Coast falcata. The bole form characteristics of Solomon falcata provenances was very superior compared to the other six provenances. It was straight, smooth and less branchy. Of the total number of Solomon provenance trees in the plots, 65 percent were given a rating of 5 Rd 72-2 location, and 40 percent received a rating of 4 at Rds 5A3 and 2. Canker incidence among the falcata provenances was negligible on the 11th year which implied that P. falcataria provenances were tolerant to the disease.

Abstract:
Air seasoning studies were conducted on samples from five fast-growing tree species, viz. Kaatoan bangkal [Anthocephalus chinensis (Lamk.) Rich. ex Walp.], Moluccan sau [Paraserianthes falcataria (L.) Nielsen], gubas (Endospernum peltatum Merr.), bagras (Eucalyptus deglupta Blume) and yemane (Gmelina arborea R. Br.) under prevailing climatic conditions in College, Laguna. REsults indicated that 25-mm thick samples required 135-150 days, 95-108 days and 66-78 days to attain average minimum MCs of 16.9%, 15.9% and 15.2% for slow, moderate and fast-drying periods respectively. The 50-mm thick boards dried in 174-198 days, 134-166 days and 90-119 days to attain average minimum MCs of 17.1% for the slow-drying period and 16.2% for both the moderate- and fast-drying periods, respectively. Likewise, 25-mm and 50-mm thick boards took 32 and 59 days, respectively: to attain "shipping dry" condition (about 30% MC) depending on the exposure period. Below low density species, Kaatoan bangkal, Moluccan sau and gubas are classified as very easy to dry, while bagras and yemane as easy to dry.

Ecosystems Research Digest;ERDS-DENR 1(1): 19-24(1991)

Abstract:
The study evaluated the growth regulator requirements of mollucan sau for callus formation using eight modifications of marashige and skoogs medium. The constituents except agar were mixed, pH adjusted between 5.6-5.8 after which agar was added. Results showed that stem tissues of mollucan sau were found promising for tissue culture propagation. The 2,4-D and NAA could induce callus of the test species. The difference lies in the length of time the callus was initiated. Both auxin possessed stimulating effect on growth of callus with 2,4-D to be greater than NAA. Therefore, murashige and skoogs basal medium supplemented with growth regulators can support callus production for mollucan sau.

The study revealed that raising falcata seedlings in the nursery under plasti shed for 24 to 38 days (from date of sowing) and subsequently exposing them in the open for 7 to 21 days resulted in shorter but hardened seedlings. Seedlings kept under the shed for 24 to 31 days and then exposed in the open for 14 to 21 days gave better field survival and growth rate than unhardened seedlings. The 14 to 21 days period of hardening in the nursery is therefore recommended for falcata seedlings.

Reforestation with fast-growing exotics versus rehabilitation of forest ecosystems with nateri tree species in Southeast Asia

Abstract:
Following a theory developed by Ulrich (1987,1992 and 1994) a definition of forest ecoystem is given and explained based on the irreversibility of fluxes. The steady state of a forest ecosystem is defined by equal rates of primary production (photosynthesis) and secondary production (respiration including mineralization. Deviations from steady state can be assessed by measuring input and output of bioelements and changes in biodiversity (Schulte, 1996).|According to this forest ecosystem theory both selective logging and conversion of Dipterocarp forest to plantations are discussed using data from case studies in Southeast Asia. The conversion of natural logged over Dipterocarp forest ecosystems into monocultures of fast-growing tree species cannot be considered a sustainable management for due to nutrient deficiencies often as early as second generation as well as the eradication of species. Under special conditions sustainability might be possible applying selective logging of Dipterocarp forest ecosystems in it's reduced impact form.|Nevertheless the Southeast Asian government establish more than one million ha of planting forest with fast-growing trees per year-manly after conversion of logged over low volumes forests. As a consequence, the chemical and biological soil amelioration, or better ecosystem rehabilitation, on millions of ha will be the main task for forestry in Southeast Asia during the coming decades.|Despite adverse conditions, it has been shown that seedlings of some native tree species can survive and grow fast even on log landings and trails if soil amelioration treatments are used (Nussbaum and Hoe, 1996). In addition, experiments in Kalimantan Indonesia clearly indicate good prospects for enrichment planting of native trees even in heavily logged-over low volume forests (Adjers et al. 1994). With the observed increment of 8-17 m3 ha-1 year-1 and current high prices of "red meranti" timber, rehabilitation seems to be much more profitable than the commonly applied practice of converting low-volume Dipterocarp forest ecosystems to monocultures of fast-growing exotic tree species.|Forest ecosystem rehabilitation experiences with native tree species in Southeast Asia will be presented and summarized in form of a review. Suggestions for generalized rehabilitation management of unproductive wasteland and logged over forests will be discussed.

Abstract:
This study presents the indicative average physical and mechanical properties of 11 plantation-grown timber species in the Philippines. The properties were determined from tests on small clear specimens of timber. Properties studied include relative density, shrinkage, bending, shear-parallel-to-grain, compression-parallel-to-grain and compression-perpendicular-to-grain, hardness and toughness. Based on the classification of the species in accordance with the five physico-mechanical property groupings devised by FPRDI, (a) giant ipil-ipil, Benguet pine, big-leafed mahogany, yemane and teak are recommended for medium construction purposes; (b) para-rubber for moderately light construction; and (c) kaatoan bangkal, moluccan sau, gubas, bagras and lumbang for light construction purposes where strength and durability are not critical requirements. The values presented only apply to defect-free materials and care should be taken when they are used for structural design purposes.

Abstract:
Albizia falcataria seedlings about 3.5 cm tall were planted on 8 kinds of unsterlized potting media in plstic film bags. The results showed that unwashed river sand is a very poor medium and, therefore, should not at all be used. Humus performed best in terms of height growth of the seedlings but the survival was so poor that it is not recommended unless thoroughly sterilized. Ordinary garden soil was second poorest in height but it gave the highest survival.|The 1:1 mixture of ordinary garden soil and sand gave the best combination of survival and growth, followed by the clay medium and ordinary garden soil without sand, 2:1 garden soil-sand mixture, and 1:1 humus-sand mixture is also satisfactory because there is a maximum period of 13 weeks for growth between potting and outplanting time.

Direct seeding was a failure due to attacks of African snail (Achtina fulica Boudich). The pruned seedlings were also complete failures. Spacing did not have any effect on survival and height growth either in the first year or second year after planting. Spcaing did not have any effect on diameter growth in the first year, but diameter growth in the second year was significantly faster in the 2 x 2 m that with 1 x 1 m, by 2.3 cm.|Survival in the first year of the potted seedlings was significantly higher than survival of the barefoot seedlings but they had about the same survival in the second year. Diameter growth in both years was about the same for potted and barefoot seedlings. The potted seedlings had significantly faster height growth in the first year that the barefoot seedlings. In the second year, however, height growth was about the same for both kinds of planting materials.

Abstracts of Researches on High Premium and Fast-Growing Species; Forestry Research Institute; 1977; Generalao,ML(compiled by); Philippine Council for Agriculture and Resources Research, Los Baños, Laguna, Philippines; pp.65

Abstract:
When the plantation was 5 years and 9 months old, the surviving trees were measured for their average diameter at breast height, clear length and total height.|On the slope with 114 trees, total height average 13.3 meters, clear length 6.5 meters and clear length volume 0.1338 cubic meters. Average annual height increment was 2.2 meters.|On a level ground with 23 trees, diameter (dbh) average of 19.3 cm, total height of 11.1 meters, clear length volume of 0.1229 cubic meters. Average annual height increment was 2.0 meters.|However, 11 trees spaced 4 x 4 meters produced an average clear length volume of 0.2238 cubic meters. In the plot, a tree with 3 sprouts grown from stump produced a clear length of 0.6360 meters.|This shows that the species when grown from coppice may increase its volume yield by about 3 times.

Study on the effect of slope and spacing on the survival of the Albizia falcataria (L.) Back. in Nueva Viscaya plantation


Maun, MM; Romero, UM
Abstracts of Researches on High Premium and Fast-Growing Species; Forestry Research Institute; 1977; Generalao,ML(compiled by); Philippine Council for Agriculture and Resources Research, Los Baños, Laguna, Philippines; pp.66

Abstract:
Seedlings planted in each plot were inventoried every month for 12 months to determine the percentage of survival. The clear length, total height and diameter breast height were measured yearly for 5 years.|Block I, located along a slope with clay soil, obtained the highest survival, followed by Block III, located on a ridge, then Block II which is on a level ground.|Survival of seedlings was not significantly affected by spacing different.|Greater percentage of mortality occurred during the wet months, July to January than during dry months, February to June. Mortality is mainly due to strong rains and winds, fast penetration of wild grasses into the planted blocks and activities of wild hogs.

Potential of forest plantation species for pulp and paper and reconstituted products industries


Mohd Nor, MY; Salleh, MN
Forest Research Institute Malaysia Kepong; 52109 Kuala Lumpur

Proceedings of the National Seminar on Economics of Forest Plantation; 24-26 February 1992; Petaling Jaya; p145- 159

Abstract:
The establishment of a format plantation will provide a steady source of fibrous raw material to the wood-based industries when the supply of existing raw materials faces depletion or becomes more expensive. The suitability of format plantation species for pulp and paper and reconstituted products has been established but their commercial utilization potential has yet to be realized. Before considering setting up a pulp and paper mill several factors need to be considered such as the availability of fibrous raw material to sustain its continuous operation and the scale of operation required depending on the investment capability and market demand. A comparison of the scale of operation between the pulp and paper and reconstituted products industries is presented to illustrate the investment required for a given production capacity.

Department of Land Management; Universiti Putra Malaysia, 43400 UPM, Serdang, Selangor

13th. Malaysian Society of Plant Physiology Conference: "Towards Sustainable Development in Agroforestry: New Paradigm for Plant Physiologists"; Kuala Lumpur; 10-12 September 2002; p16

Abstract:
The use of chemical fertilizers for mitigating N deficiency is unsustainable in many tropical areas because of economic constraints and possible deleterious effects on environmental quality. Organic inputs such as green manures and litter from legumes have shown some potential for improving soil N status. Below-ground biomass of tree legumes in agroforestry systems is generally ignored in nutrient cycling studies because of cumbersome measurement methodologies involved. Yet, roots can provide a significant amount of N in form of dead roots, nodules and rhizodeposition. In agroforestry cropping systems, fine root decomposition is likely to be an important source of nutrients because it occurs within the crop-rooting zone. This study aims at measuring the nitrogen contribution by Batai trees (Paraserianthes falcataria), a N2-fixing tree, to an associated corn crop, using direct and indirect I-N isotope labeling techniques. The P. falcataria mixture treatments showed cob yield significantly higher than the control but not significantly higher than the other treatments. The com grown in soils treated with P. falcataria mixtures and P. falcataria roots alone had the highest yields of N. The highest percentage of N contributed to corn was from the P. falcataria roots alone (averaging 57%) followed by the P. falcataria roots when they were combined with leaves (40%). The N contribution of P. falcataria leaves whether in mixture (10%) or when used alone (14%) was relatively low and not significantly different. Both 15N-labeling methods showed similar results for quantifying N contribution by P. falcataria to corn.

Proceedings of a workshop on Leucaena Research in the Asian-Pacific Region, 23-26 November 1982, Singapore, Ottawa, Canada, International Development Research Center, 1983; p 155-158

Abstract:
In 1974, Sabah Softwoods Sdn Bhd was created to manage a 6.0 X 104 ha afforestation program; to date. it has planted 2.3 X 104 ha. some of which include Albizia falcataria, Acacia mangium. and Leucaena leucocephala. Data on height and diameter are being collected, and preliminary indications are that Albizia falcataria, planted at 600 -900 stems1ha is sawlog class by age 8 years: that, at the some spacing, A. mangium has a mean annual increment in volume equal to 30 m3/ha; and that timing is essential in the soils of Sabah where Leucaena leucocephala is grown but is regarded as uneconomic (Author's abstract).

Proceedings of a workshop on Leucaena Research in the Asian-Pacific Region, 23-26 November 1982, Singapore, Ottawa, Canada, International Development Research Center, 1983; p 113-118

Abstract:
Leucaena leucocephala seldom exceeds 20 m high and usually stops growing at 15 m or less in most sites in Malaysia. Hence, it is too small to be a sawlog species. However, because it is fast growing, it may play a useful role as a tall cover crop in sawlog plantations where the sawlog species is expected to grow to 30 m or more. Preliminary results of trials with Leucaena leucocephala as a cover crop for teak and Araucaria sp. have proved promising (Author's abstract).

Proceedings of a workshop on Leucaena Research in the Asian-Pacific Region, 23-26 November 1982, Singapore, Ottawa, Canada, International Development Research Center, 1983; p 149-154

Abstract:
The importance of high growth rates of trees in the tropics is highlighted, particularly in relation to the future demands for wood products in Asia. In Sabah, Malaysia, the need for high volumes of wood and for tree legumes in reclamation of land degraded by excessive cultivation has prompted tree planting and trials with two major species: Acacia mangium and Albizia falcataria. Two other spccies. Acacia auriculiformis and Gliricidia sepium are mentioned the latter grown primarily for its value as cocoa shade in the state. Special attention is drawn to the importance of seed origin and the dangers of over expanding populations of limited genetic base. The biological ease with which some species can be generatively or vegetatively propagated makes overexpansion a real possibility (Author's abstract).

Visose by the xanthation process for rayon from mollucan-sau


Francia, PC
FORPRIDE Digest 6 (1): 9-16 (1977)

Abstract:
The potential of Mollucan-sau [Albiaza falcataria(L.)Forsberg] as a raw material for dissolving pulp in the preparation of viscose for ryaon and cellophane offers a good prospect for the utilizationof a fast-growing wood species. Laboratory transformation of the dissolving pulp into viscose, ripened on the sixth day;obtained a Hottenroth index of 9.1, salt point index of 3.7, alkali content of 7.21% and cellulose content of 6.21%. The HOttenroth number of viscose solution with 10 or less is technically ready for spinning. The lower the salt index the riper is the viscose. Oxidation during aging leads to chain scission and by the peeling mechanism the cellulose chain breaks and this leads to a decrease in viscocity. The decrease in viscocity during ripening was brought about by tye dexanthation and rexanthation of the viscose.

Physical and chemical properties of viscose rayon from Mollucan sau (Albiaza falcataria (L.) Fosberg)


Francia, PC
FORPRIDE Digest 5: 14-21 (1976)

Abstract:
Visocose-rayon fiber was produced from Mollucan sau dissolving pulp at the following conditions: 17.5% of alkali concentration used in the mercerization of the cellulose;temperature of the spinbath at 35 degree C;spinning rate (stretch of 40 m/min;and immersion length (distance between the spinneret and the sampling point measured along the filament path) of 40 cm. Physical and chemical properties of the yarn was determined. The density of the viscose fiber was 1.52 + - 0.01 gm/cm3 and had shrinkage value of 1.12 + - 0.01. It was insoluble in most solvent tested except sulfuric acid and glacial acetic acid in which it was readily soluble;it was stained readily by the dyes used and showed an irregularly oval-shaped cross section with outer scalloped edges. When burnt, it leaft an ash skeleton. The physical and chemical properties of the experimental viscose conformed with those of commercial samples.

Pterocarpus 1: 1-5 (1975)

Abstract:
Kaatoan bangkal, Anthocephalus chinensis (Lamk.) Rich ex Walp., and Mollucan-sau, Albiaza falcataria (L.) Fosb., trees were planted in pure and mixed stands to determine differences between mixed and pure stands of the same species in terms of growth and damage by destructive agencies.|Results showed that mixing the two species had no advantage over pure stands of the same species in terms of both volume growth and survival. Insect infestation was very light, and no difference was observed species or between pure and mixed stands. More Mollucan sau were broken and wind-thrown than Kaatoan bangkal trees.

Decay following typhoon in Mollucan sau [Albizia falcataria (L.) Fosb.]


de Guzman, ED
Pterocarpus 2 (2): 156-159 (1976)

Abstract:
The relationship of typhoon to decay development on Albizia falcataria was investigated. Decay fungi gained entrance through broken branches, stem wounds and root injuries or a combination of these. The size of the wound was an important factor in the development of decay. Decay was confined to sapwood although some trees developed center rot. White rot type of decay was mpre common than brown rot type. Several species of Basidiomycetes were found commonly associated with decay.
