Genetically pure species that used as genetic materials represent crucial factors for succeed of a tree improvement strategy. Using microsatellite markers, private allele and genetic variation could genetically distinguish a species. Aims in this study were to characterize microsatellite markers on Eucalyptus deglupta, E. urophylla and E. pellita, and to assess private allele and genetic variation on the tree Eucalyptus. Results showed that 8, 10 and 12 out of 13 the screened microsatellite markers were amplified and polymorphic on E. deglupta, E. urophylla and E. pellita respectively. Private alleles characterized each Eucalyptus. Number of detected allele ranged between 29 (E. deglupta) and 91 (E. pellita). Value of expected heterozygosity was lowest on E. deglupta (HE=0.308) and highest on E. pellita (HE=0.604). Coefficient inbreeding value was insignificant deviate from HWE on E. deglupta and E. urophylla, but it was significant on E. pellita. Taxonomy relationship and geographic position in natural distribution each Eucalyptus was discussed. For further study, population genetic and mating system will be important information on the Eucalyptus.

One of the purposes of seedling seed orchard (SSO) establishment is to produce genetically improved seeds. The amount of genetic gain in the SSO is determined from a series of selection involving within and between family selection in which the gain is generally achieved from the accumulated increases of gain in successive advanced generation breeding cycles. In present study, the amount of genetic gain was predicted in third-generation SSO of Acacia mangium after first within-plot selection using a retrospective selection index’s method. The SSO was established in Wonogiri, Central Java which was laid out in a randomized complete block design, 65 families, six replications, four trees-line plot and spacing of 2 m x 4 m. Actual within-plot selection was subjectively practiced in 40 months after planting. The observed traits for genetic gain prediction was height, diameter at breast height (dbh), and stem straightness using data collected at 24 months after planting. For calculating genetic gain based on multiple trait selection index, coefficient weight for each trait was then derived from the selection differential. The results of study showed that the first within plot selection was practiced mostly for imposing dbh rather than height or stem straightness with the relative gain was 6% for dbh, and 3% for both height and stem straightness. Using the derived coefficient weight, the expected genetic gain by family selection was found to be slightly lower than those predicted by within-plot selection at 3% for dbh, and 2% for both height and stem straightness.

This study aimed to identity characteristic and variation of A. Mangium wood physical properties in different planting spacings and axial-radial position. Materials used were 8 years old Amangium wood from Subanjeriji, Palembang, South Sumatera with three spacings: 2 m x 3 m, 2 m x 4 m and 3 m x 3 m. Three sample trees in diameter of 21 cm from each planting spacing were taken by randomly. Specimens in each tree were taken in 3 axial position (bottom, middle and top of trunk), and 3 radial position (near pith, middle and near bark). Parameters measured were wood density, fresh moisture content (FMC), equilibrium moisture content (EMC), total tangential shrinkage (TS), radial shrinkage (RS), longitudinal shrinkage (LS) and T/R ratio (T/R). The result showed that total averages of wood density, FMC, TS, RS, LS, and T/R were 0,45 gr/cm3; 118,40%; 7,63%; 3,53%; 0,71% and 2,23% respectively. Differences on wood physical properties of three spacing were found at FMC, TS and LS; while other properties were relatively not different. Based on the density, FMC and dimension change A. Mangium wood grown in 2 m x 4 m plantation spacing showed the best performance, that followed by 3 m x 3 m and 2 m x 3 m. Based on axial orientation, wood density tend to increase from bottom to upper stem, FMC, EMC, and TS, while other properties were not different. Based on radial orientation, the wood density and TS tend to increase from near the pith to near the bark, while FMC and LS have reversed pattern.

Agarwood is a non timber forest product (NTFP) with a high economic value. Gyrinops versteegii (Gilg) Domke was an endemic and rare plants, however, it is cultivated on the island of Lombok. The study of shoot multiplication from single node stem and cotyledon node explants to shoot produced was conducted to find out the best method to shoot multiplication. Modification of Murashige and Skoog (MS), Gamborg (B5) dan Woody Plant Medium (WPM) supplemented with 8.0 g/l agar, 30 g/l sucrose and vitamin (0.1 mg/l Thyamine, 0.5 mg/l Nicotinic acid, 0.5 mg/l Pyridoxine dan 2 mg/l Glysin) and 10 g/l myoinositol were used as growth medium treatments. The experiment was conducted on two stages i.e. germination and shoot multiplication. Shoot induction was conducted on modification of MS medium supplemented with Benzyl Adenin (BA) 0.5; 1.0 and1.5 mg/l. The multiplication of shoot conducted on modification of MS medium, WPM and B5 medium supplemented with 0.5; 0.75 dan 1.0 mg/l Benzyl Adenin (BA). For every treatment there were ten samples (bottles) with one explants in each bottle. The observation was conducted on shoot induction percentage, number of shoot and visual performance of culture. The result showed that modified MS + BA 0.5 mg/l was the best for shoot induction from single node stem explants with the average of 1.6 shoots on 12 weeks. The treatment of modified MS + BA 0.75 mg/l was the best for shoot multiplication from single node stem explants with the average of 5.7 shoots on 12 weeks. The treatment of modified WPM + 0.5 mg/l BA was the best for shoot multiplication from cotyledonery node explants with the average of 4.6 shoots on 12 weeks. The visual performance of shoot resulted was normal.

Along with the increase of forest plantation development to supply raw material for industry, the utilization of marginal land with high salinity is likely to be an alternative for the plantation of A. mangium. In an effort to increase the improvement of A. mangium to be extensively planted on the widely alternative land, breeding programs were conducted to get trees of A. mangium which are tolerant to environmental stress, such as salt stress. The purpose of this study was to observe the anatomical response of A. mangium collected from several seed sources to salinity stress as a basis for salt tolerance breeding program. The trial consisted of four seed sources arranged in Completely Randomized Design with four level salt stresses(0; 22; 26 and 30 g/l) and 3 replications. The four tested seed sources are two seedling seed orchard (SSO) originated from Papua New Guinea provenance (namely group A and B), one SSO originated from Far North Queensland provenance (group C) and one SSO originated from a combining both provenances (group E). The treatment is given by watering the seedlings from each provenance with saline solution in accordance with a predetermined concentration of 200 ml per day for 4 months. The observed parameters were stomatal index, length dan width of stomata, number and diameter of trachea, and chlorophyll content. The results showed that in general the differences in salt co ncentration provided a significant effect on anatomical response of A. mangium. Except for the length of stomata, seed source variations were significantly different for all parameters. Meanwhile, seed sources x salt level interaction did not significantly affect the length and width of stomata. The higher the salt concentration, the lower the stomatal index and chlorophyll content. Conversely, the higher the salt concentration, the higher the amount of the tracheid. However the differences in salt concentration did not give a significant effect on diameter of tracheid. Overall, among the four tested seed sources, group B which is originated from Papua New Guinea provenancewas found to be the most tolerant seed sources to salt stress.

The objective of the study was to determine the effect of arbuscular mycorrhizal fungi collected from soil of teak plantation forest on the growth of teak seedling related to mycorrhizal association development. The study utilized the complete randomized design with three levels of inoculant’s factor, consisting of control (uninoculated), inoculation with Gigaspara spores and inoculation with Glomus spores inoctilated, with ten replications. Spores isolated originated from soil of teakplantation forest in Tangen, Surakarta. The planting medium was a mixture soil sand at 1:1 (v/v) sterilized prior to be used. NPK mixed ferfilizer was applied at amount 0,0625 gr per seeadling mixed in to the planting medium. Measurements were conducted during a five month period. The data were analyzed using the Analysis ofVariance method and differences among treaments analyzed usfing the Duncan’sMultiple Range Test at the 5% ievel of significance. The results showed that inoculationwith the arbuscular mycorrhizail fungi increased teak seedling growth, with Gigaspora sp inoculation giving the highest growth. The uptakes of N, P, K and Ca were increased by both Gigaspora sp and Glomus sp inoculations. The increased seedling growth, was accompanied by large increases in infection percentage as well as sporulation. The highest infection and sporulation were found with Gigaspora sp inoculation. These results showed that in the soil ofteak plantation forest in Tangen of the grumusol type, relatively low NPK fertilization (0,0625 gr per seedling) and inoculadon with spores ofarbuscular mycorrhizal fungi improved teak seedling growth, inereased nutrient uptake, as well as improved mycorrhizal association development in teak seedlings.

Merbau is one of threatened forest genetic resources. Based on IUCN Red List Categories. conservation status of merbau is vulnerable (VU A1cd). Conservation effort of merbau is urgently required to save this species from extinction. Center for Forest Biotechnology and Tree Improvement Yogyakarta had established ex situ conservation plots of merbau in Forest Research in Bondowoso, East Java and Gunung Kidul Yogyakarta. Genetic resources used in those ex situ conservation plots were from seven provenances namely Halmahera Timur, Waigo, Oransbari, Wasior, Nabire, Seram, dan Mandopi/Twanwawi. This research aims to evaluate adaptability, growth and regeneration of merbau plants grown in ex situ conservation plots in Bondowoso dan Gunung Kidul. The ex situ conservation plot in Bondowoso was designed as Randomized Complete Block Design with single factor of provenance. At the ex situ conservation plot in Gunung Kidul each provenance was planted in one block. The results showed that adaptability of merbau plants at ex situ conservation plots in Bondowoso dan Gunung Kidul was good. Growth of height and diameter of merbau plants from several provenances at ex situ conservation plot in Gunung Kidul were better than those in Bondowoso at all observation ages. Height and diameter average of merbau plants at ex situ conservation plots in Bondowoso and Gunung Kidul at one year old were 78.21 cm; 9.58 mm and 97.88 cm; 9.58 mm respectively. Height and diameter average of merbau plants at ex situ conservation plots in Bondowoso and Gunung Kidul at two years old were 95.36 cm; 12.95 mm and cm; 19.62 mm respectively. Regeneration of merbau has been successful at Gunung Kidul plot. Some of the fallen seeds were then grown to be wildlings. Whereas, regeneration of merbau at ex situ conservation plot in Bondowoso was regarded as not successful

Waterloging and salinity in many places in the world are affected by natural conditions, geological history, irrigation practice and replacement of natural vegetations. Ground water might bring salt to soil surface at root zone areas. Engineering and vegetations are commonly used to anticipate this problem. Provisions of vegetations tolerate to this typical salty condition, although take a longer time to solve, are much cheaper and effective means to control salinity and even to rehabilitate the lands. E. occidentalis, a highly tolerant species to those conditions need to be tested as an alternative species for plantation under these conditions. Genetic materials from its natural distribution were tested to find out the most tolerant provenance under inundation and high salt level.Two controlled testings using 9 E. occidentalis provenances were conducted reaching to 300 mM salt and followed by an increased level up to sea salt concentration (550mM NaCl). Provenances from the same genetic materials were also tested in 3 field trials, i.e.: in Roberts, Sandalwindy and Kirkwood with different ranges of salt level.At salt concentration of 300mM, E. occidentalis growth was not affected, and therefore this level is too low for selection. Plants were depressed under 550mM salt and differences between provenaces are much more obvious. Different performances under high salinity were obtained from controlled condition and in field trials. Provenans Red Lake Siding and Grass Patch originated from the most extreme arid conditions nearby salty lakes showed the best ability to grow under high saline exposures on both testings.
