Abstract

Genetic diversity and relationship of four Acacia species, Acacia aulacocarpa, A. Cunn. ex Benth., A. auriculiformis Cunn. ex Benth., A. crassicarpa Cunn. ex Benth. and A. mangium Willd. were investigated using DNA molecular markers. Using RAPD analysis, a total of 20 arbitrar y primers successfully gave 127 polymorphic fragments. These RAPD data were used to estimate genetic distance and construct dendrograms using the unweighted pair-group with the arithmetic mean average (UPGMA) method. The four species were divided into two major clusters. A. auriculiformis and A. mangium were in one cluster, and the other cluster contained both A. aulacocarpa and A. crassicarpa. The divergence time of the two species (A. auriculiformis and A. mangium) in the former cluster appeared to be relatively early in comparison to in the latter (A. aulacocarpa and A. crassicarpa) based on RAPD data. This result was also supported by Principal Component Analysis (PCA). Among the four species, A. aulacocarpa showed the highest divergence in nuclear DNA (ncDNA), followed by A. auriculiformis. SSCP analysis also revealed that these two species possessed a haplotypic variation of the trnL-trnF intergenic spacer region of chloroplast DNA. In A. aulacocarpa, a large difference in the composition of both nuclear and chloroplast genomes was obser ved between populations distributed in Queensland, Australia and those in New Guinea Island. In contrast, compared to the other species, A. mangium showed the lowest genetic diversity and less genetic differentiation among populations.

Abstract

A study on demography,  growth  and survival of  seedlings and saplings was conducted  in the Hutan Kintap  concenssion,   South Kalimantan,   Indonesia. The aim of  the study  was to monitor  pattern  of growth of seedlings and saplings among different types of logged -  over forest, including the newly  logged  -  forest, older  logged  -  over forests   (treated and untreated),   and un-logged-forest    patches.   The  study began in 1991, and nineteen  of  0.25  ha plots   were set up in a total  of  six blocks  designated   as consecutively  A, B, C, D, E and F.  Block A was a newly logged   forest and had five plots,  and Block  B -  D were in forest which  had been logged  in 1979.  Block B (five plots) had received no silvicultural   treatment,  while Block  C (five plots) and  D (one plot)   had  been  lightly   thinned  after  felling and  further  Block C received  a further  thinning treatment   Block  E (one plot)  had been  heavily   thinned,  and Block F (2 plots)   was an un-logged   control. The  density  of  seedling  varied within  the study sites, and averaged  from  47,000 ha"  to 121,000   ha·1•   The mean height increment  of  seedlings varied among block ranging from 2.9  cm year'  to 10.5  cm year".  Block A had the highest general  mean  increment  of  10.5  cm year",   followed  in decreasing  order  by Block C of 5.4 and Block F, 4.5  cm year".  Growth  of  seedling in Block  B was low, even lower  than  the growth  in the un-logged   Block F. The  difference  of the increment among Block A, B, C and F however was not significant. The liberation treatment  in Block C significantly   resulted in a higher (p<0.01)  increment  (5.4 cm year") than that in  the untreated  Block  B (2.9 cm year").  Seedling  mortality ranged from 16 to 37 % year", and declined with  height   class. The  mortality  of  seedlings  might  be related  among  other  factors  to the  humidity  and density  of  seedlings per-unit  area. The  density  of  sapling ranged  from 6,800 ha" to 7,700  ha" and they had diameter  growth  of  0.8 mm  year" to  2.2  mm year",  and height   growth  of  12.6  cm year" to 21.8  cm year"1. The  difference  in the  diameter  increment   among  block  r\, B,  C and  F was  not  significant.    The  average sapling height increment  varied (but not significantly so) among Block,  ranging from 12.6  cm year" in Block A to 21.8  cm year" in Block C. Mortality  of  sapling was relatively   low  in all block.  Higher  mortality  in the un-logged   forest  Block  I' and  in the untreated  Block B might  due to  the low  degree  of  canopy   opening.

Abstract

Various experimental testing procedures were undertaken in Indonesia to determine the effectiveness of a patented superficial (envelope) treatment using bifenthrin to protect radiata pine framing material from damage by two species of subterranean termites (Macrotermes gilvus and Coptotermes curvignathus) and one species of drywood termite (Cryptotermes cynocephalus). Lengths of framing material (Pinus radiata sapwood) were commercially treated to the targeted retention of 0.02% m/m of bifenthrin in the outer 2 mm depth penetration zone of the material. The treated and untreated materials were subsequently cut into test specimens and exposed to M. gilvus in the field and a semi-laboratory trial, to C. curvignathus in the laboratory and a semi-laboratory trial and to C. cynocephalus in a laboratory trial. No supplementary treatment was performed on the exposed cut ends of the treated test specimens. The results from the trials clearly demonstrated that the superficial treatment of bifenthrin seemed effective in protecting test specimens of radiata pine framing material from significant damage by Indonesia’s most notorious termite species that often causes serious economic loss to the timbers. Termites were unable to damage any of the bifenthrin-treated surfaces of test specimens. Any obser ved damage by termites, albeit minor, was in all cases confined to the exposed cut ends of test specimens. In contrast, attack by termites on the untreated control test specimens caused damage of the samples ranging from light to heavy.

Abstract

The fiber-plastic composites were made from the compounding of plastic (polypropylene) and sisal  (Agave sisalana)fiber with or without  addition of coupling agent (Maleic anhydride grafted polypropylene).  The tensile  strength (Modulus of Elasticity-MOE, Modulus of Rupture-MOR) of the composites were evaluated in the three different conditions, i.e. air dry condition (control), 24 - hour immersion in cold water and 2-hour immersion  in boilingwater.  The results showed that the addition of coupling agent enhanced the properties of the composites.   These properties did not significantly change although  the composites  were immersed in cold water as long as 24 hours.    However, immersion in boiling water for 2 hours, tended to decrease MOR and MOE of the composites.

Abstract

Aren (Arenga pinnata Merr.) is a multipurpose tree that can be utilized for palm sugar, alcoholic drinks, beverages and construction wood. The use of  aren sawdust has not been studied intensively. This study examines the utilization of  aren sawdust as cultivation media for edible mushrooms. Aren sawdust was mixed with rice bran, CaCO3, gypsum, fertilizers and distilled water before sterilization in 30 minutes pressurized autoclave at 1210C and 1.5atm. The mixed media was inoculated with pure cultures containing four mushrooms species (Pleurotus flabellatus, P. ostreatus, P. sajor-caju and Lentinula edodes) and incubated for five weeks to allow mycelium growth producing fruit bodies. The fruit bodies were harvested everyday within four months and examined for its gained mushroom-weight and biological conversion efficiency/BE. The core part of  aren trunk was cut into smaller pieces of  10 cm (width) by 5 cm (thickness), by 120 cm (length). Each core sample was bored from the surface inward, creating holes with a particular distance apart. Each hole was inoculated with pure cultures containing 6 mushroom species (four species above, P. cystidiosus and Auricularia polytricha). The inoculated samples were slanted on bamboo support, and placed in a bamboo hut. Harvesting was carried out everyday after the fruiting body became mature and examined for its gained mushroom weight. Results show that the use of  sawdust supplemented with nutritious material is more likely to improve the mushroom yield than that of  aren sawn-timber core.  In this case, the BE values with aren-sawdust media were 21.97-89.45% (P. flabellatus), 15.36-105.36% (P. ostreatus), 63.88-76.86% (P. sajor-caju), and up to 62.88% (L. edodes). Meanwhile, the yields (gained mushroom weight) with aren sawn-timber media were 210g (P. ostreatus), 368g (P. flabellatus), 331g (P. sajor-caju) and 48g (A. polytricha); however, P. cystidiosus and L. edodes inoculated on aren stem core failed to grow.

Abstract

Provenance trial is a planting test aimed at fi nding the best provenance for establishing forest plantations. Such best provenance depends on the type of fi nal harvest or yield expected.  The objective of this research was to identify A. mangium provenances that were suitable for forest plantation producing solid woods for construction and furniture. A total of 225 samples of 15 provenances from Papua New Guinea and Australia were planted in three blocks in Parungpanjang, Bogor, West Java. The measured parameters included tree height, clear bole height, stem diameter, tree volume, stem form, branching habit, and crown form. Bi-plot analysis indicated that Kini WP, Keru Village WP, Derideri R. Morehead, and Claudia River were the best provenances in terms of productivity. Correspondence analysis showed that almost all provenances were equally good in stem form, but they varied in branching system as well as crown form.  Provenances Kini WP, Keru Village WP, Kiriwo/Serisa WP, and Bimadebun Village possessed the better branching habit.  In terms of crown form provenances Dimisi Village WP, Kiriwo/Serisa WP, and Derideri R. Morehead exhibited a good performance. In general, fi ve provenances, i.e. Kini WP, Keru Village WP, Derideri R. Morehead, Kiriwo/Serisa WP, and Claudia River were considered appropriate for seed sources supplying seeds for industrial plantation development intended to produce construction and furniture material.

Abstract

The magnitude  of the genotype-environment interaction (GEI) in seven six years  old seedling  seed orchards  of Eucalyptus pellita established  at three locations  in Indonesia  was examined  by analyzing height  and diameter.  The seed orchard  at each location  consists of 121 families  from three  provenances  of Papua  New  Guinea.  The pooled  sum of squares derived from analysis  of variance  of growth  of the three provenances  was used to estimate genetic  parameters.  These parameters  were  then used to calculate  genetic  gain as a result of both direct and indirect  selections.  The GEI across the three locations  was very  strong, while the results of pair-wise site analysis  varied between the pairs of locations.  The genetic correlations for pairs of locations  were moderately high between South Sumatra  and Riau;0.68 for dbh and 0.85 for height,  but were lower  between South Kalimantan and the other locations  (0.32 to 0.56). The gains resulting  from direct  selection  were  apparently greater than those resulting  from indirect  selection.  The genetic  gains achieved  in South Sumatra and Riau  would  decrease by 24% as a result  of transfer  to other  sites, while  transfer  from South Kalimantan to Sumatra  Island (and vice versa) would  reduce in the genetic  gain by 60%. Hence, the breeding  population in South Kalimantan should be developed separately from those in South Sumatra  and Riau

Abstract

This study describes the establishment of  a compatible volume estimation model for Acacia mangium Willd on the basis of  279 felled sample trees collected from the A. mangium plantation stands in South Sumatra, Indonesia. The model comprises of  a total volume model and a stem taper model, which is compatible in the sense of  the total volume obtained by integration of  the taper model being equal to that computed by the total volume model. Several well-known total volume functions were evaluated including constant form factor, combined variable, generalized combine variable, logarithmic, generalized logarithmic and Honer transformed variables. A logarithmic model was determined to be the best and was then used as the basis for deriving the taper model. Appropriate statistical procedures were used in model fitting to account for the problems of  heteroscedasticity and autocorrelation that are associated with the construction of  volume and taper functions. The simultaneous fitting method of  the Seemingly Unrelated Regression (SUR) improved the parameter estimates and goodness-of-fit statistics while ensuring numeric consistency among the component models and reducing the total squared error obtained by an independent fitting method. The developed model can be used to estimate total stem volume, merchantable volume to any merchantability diameter limit at any height, and (possibly) height of  any diameter based on only easily measurable parameters such as diameter at breast height and total tree height for the species analysed.
