Realized genetic gain of improved seed of cajuput from a breeding program and seed source x site interaction on the oil properties (1,8-cineole and oil yield) was evaluated through the establishment of genetic gain trials in two sites: Gunungkidul dan Ponorogo. Improved seed from two seed sources tested in the trials were first generation seedling seed orchard (SSO-1) and selected superior seed trees in the SSO-1 (SSO-2). As a control, unimproved seed from three seed sources: natural stands in Maluku (ST-1), plantation in Ponorogo (ST-2) and Gundih (ST-3) were also planted together in the trials. The genetic gain trial was established using a randomised complete clock design which consists of 5 tested seed sources, 20 treeplot, 8 replicates and spacing of 3 x 3m. The results of study showed that the realized genetic gain for the content of 1,8-cineole from SSO-2 over the controls ranged from 13.78% to 17.52% and the genetic gain of the oil yield ranged from 15.76% to 26,43%. Meanwhile the realized genetic gain for SSO-1 ranged from 2.07% to 5.42% and 10.15% to 20.30% for the content of 1,8-cineole and oil yield,respectively. The non-significance of seed source x site interaction indicates that all improved seed from the first-generation seedling seed orchard of cajuput in Paliyan are most likely to be adaptable to the varies site in Gunungkidul and Ponorogo while maintaining the high productivity in oil properties.

Standard method in physical and physiological quality testing is very imprortant to support a controlling system of distributed seed quality by certification that will provide a guarantee to prosedure; distributor, and user. Five seed lot of sawo kecil (Manilkara kauki) from Mokmer (Bali), Benoa (Bali), Lombar (Lombok), Kaliurang (Yogyakarta) and Alas Purwo (Banyuwangi) were used to identify the best method for moisture content and germination testing. Completely randomized design was applied to determine the best method for moisture content testing. The treatments in selection of the appropriateMethod were oven method on the temperature 130 – 133 oC (1-,2-,3-, and 4 hours) and temperature 103 ± 20C (16-,18-,20-,22-, and haours). The selection of germination method used completely randomized design with 3 factors of treatment, i.e. sowing media, pretreatment, and germination condition. The result showed that oven method at temperature 103 +_20C for 24 hours and at temperature 130-1330 C 4 hours provided the best result for seed moisture content testing. For seed germination testing, seeds sowed on the sand media with drying-wetting pretreatmen for 3 days on the germination box covered by transparent plastic provided the best germination capacity and speed toward 5 seed lots. The methods can be considered to be appied in the testing of moisture conten and germination of sawo kecik seeds.

When genetic base in a seed orchard is narrow, a startegy of genetic infusion should be applied to broaden and maintain its ganetic variation over several successive generations. For this purpose, genetic-infusion populations were established in tree improvement programs of Pinus merkusii located in jember. To be successful genetic variation of the infusion populations should be assessed. This study was aimed to determine genetic diversity of three infusion populations of P merkusii i.e. Takengon, janto and Blankejeren population using five microsatellite markersi. The results showed that gene diversity of plus trees in the seed orchard was at a moderate level (HE=0.508).Significant inbreeding deviation from the Hardy-Weinberg equilibrium (HWE) was detected (FIS = 0.073). Gene diversity of the infusion populations was comparatively high. It ranged between 0.498 (Janto) and 0.524 (Blankejeren). The FIS was low and insiqnificant deviation from HWE at any genetic infusion populations. The genetic differentiation among the populations (in both seed orchard and genetic infusion) was very low (FST=0.003) indicating that they were genetically related. It is recommended that the infusion populations have a potential to maintain to genetic diversity in the seed orchard.However, Since they are related, it is necessary to find other potential genetic infusion populations that could broaden genetic diversity more effectively in the seed ochard.

Shorea pinanga (Scheff.) is a member of Dipterocarpaceae which has an important role both as a forest timber and also non forest timber product (tengkawang). The purpose of this experiment is to obtain the best treatment for somatic embryos formation. Friable callus was used as explants whereas liquid and solid MS media supplemented with vitamin B, 30 g/l sucrose were used as basal medium. Embryogenic callus was induced through three times subcultured in basal medium with 5.0 mg/l 2,4- D. Somatic embryo was induced using 100 mg of embryogenic callus with the addition of 0.5, 1.0, and 1.5 mg/l kinetin. The observation was done on texture, numbers and color of embryogenic callus and weekly number of somatic embryos for eight weeks. The kinetin treatment of 1.5 mg/l on liquid medium was the best treatment because it is able to induce 162 cotyledonary stage of somatic embryos for eight weeks.

The study aimed to assess genetic diversity and genetic relationship of ulin wildlings randomly collected from a nursery and originated from Bukit Soeharto natural forest, East Kalimantan. DNA templates were extracted from leaf samples of 1.5 years old wildings. Five RAPD primers consisted 55 polymorphic loci were used for genetic studies. Genetic diversity and relationship were analyzed using GenAlex software. The results showed moderate mean value of genetic diversity (HE=0,345, SE 0,015) of the wildings. Forty eight wildings were clustered in only 3 groups; almost all wildings (65%) were clustered in one main cluster. Moreover, 4 wildlings were clones (8%). In conclusion, the 48 wildings of ulin consisted high genetic relationship and individual clones that reflects the low genetic diversity of this species.

Sandalwood (Santalum Album Linn) is one of high economic value foret commodities. However, over exploitation without appropriate rehabilitation has serious degradation of the natural populations caused. Therefore, an ex situ conservation of this species has been established at Watusipat, Gunung kidul in 2000. It comprised of 6 populations collected from East Nusa Tenggara . The genetic diversity of these populations was investigated using isozyme genetic marker with 3 enzymes.Shikimate dehydrogenase (SHD), Esterase (EST), and Diaphorase (DIA). Thirteen alleles were identified on fife polymorphic loci. A relatively high genetic diversity was reflected by paramaters, such as the mean number of alleles per polymorphic locus (A=2.1333); the mean effective number of alleles per polymorphic locus (v= 1.6302); the mean percentage of polymorphic loci (PPL=83.333%); the mean observed heterozygosity (Ho= 0.3951) and the mean expected heterozygosity (HE = 0.3166). Most of genetic diversity (95.62%) was distributed within population. Cluster analysis using UPGMA based on Nei S standard genetic distance reflected two main clusters : Palakahembi, Belu and Soebela constructed the first cluster; whereas Bama, Balela and Helangdohi formed the second cluster.

The superiority of Acacia hybrid (A. mangium x A. auriculiformis) compared to the parent trees as fast growth, straight bole, ligth branching, more tolerance to pest and desease and had better wood properties. In order to maintain the superiority, it should be propagated vegetatively. However, the propagation potential of Acacia spp usually decreased by increasing the age of plant (aging effect). To prevent the aging effect on Acacia hybrid, vegetative propagation of selected trees should be done before becoming too old. This study was aimed to observe morphological seedling characteristics of Acacia hybrid. The result showed that morphological seedling characteristics of Acacia hybrid were intermediate between the parents species. The development of leaves pattern was well-marked by absence of 4-pinnates leaves or number of pinnates leaves was between 4-6. In addition, the pubescence was present on the margin of pinnates and the number of main vein on phyllode were mostly 3.

The quality of sandalwood (Santalum album Linn) oil primarily depends on the compound of two major sesquiterpenes (α-santalol and β-santalol). The aim of this research was to identify variation of chemical compounds of sandalwood oil from various provenances. Fifty four samples from 8 provenances and one land race taken from 13th years old sandalwood planted at Gunungkidul, Yogyakarta Indonesia. Sandalwood powder were obtained by drilling tree at 10 cm above the ground horizontally. The samples were extracted with n-hexane solvent. Identification of chemical compounds of this essential oils were conducted by gas chromatography mass spectrometry analysis (GCMS). The GCMS investigation of sandalwood oils showed that variation compounds both among individual within provenance and between provenances were found in 11 individual from 6 provenances. Compounds such as sesquiterpene, monoterpenes, and others, were found in variying amount. The results showed that α-santalol (32.38-78.29%), β-santalol (5.45%-37.83%) were the major compounds with varying quantities of compounds range of epi-β-santalol (5.97-17.16%), P-Menth-2-En-9-OL-Trans (2.87%-8.53%), and α-sinensal (3.83-9.39%).

The objective of the study was to increase the growth of 5 provenances albizia (Paraserianthes falcataria L. Nielsen) in the nursery. The experimental design was Split Plot Design, with 5 provenances of albizia as main plot and 3 treatment (wood vinegar application, mychorrizae application and control) as sub plot. Each sub plot consited of 45 seeds as sample,. Growth parameter observed was delta height: that is different beetween measurement at the early application (3 weeks age of seedling ) and at the last measurement (10 weeks age of seedling). The data obtained then analyzed by using analysis of variance of continued with Duncan test. The result showed that mychorrizae and wood vinegar application have significant effect on the growth of albazia seedling. The best performance was shown at wood vinegar application (height average 75,48 cm and height delta 66,62 cm), mychorrizae application (height average 66,44 cm and height delta 59,22 cm) and control (height average 58, 92 cm and height delta 52, 48 cm) respectively. Provenance differences were also significant. The best performance were shown at provenance of Candiroto, Kediri, Ciamis, Wamena dan Subang. Height delta each provenance after 7 weeks application were 67,65 cm, 62,93 cm, 60,15 cm 53,37 cm dan 53,11 cm; while the total height at the 10 weeks age of seedling were 74,44 cm, 69,33 cm, 69,14 cm, 61,02 cm dan 60,80 cm respectively.
