Abstract

Growth is one of important and economic traits of jabon. Growth is not only determined by environment but also genetic factor. Seedling quality and suitable site would create well growing plants. This research is purposed to know growth characteristic of jabon from Sumbawa  provenances in nursery and after plantation as well as the effect of genetic factor on growth characteristic of jabon. Research design used in nursery is Completely Randomized Design with 24 mother trees and 3  replications. Each replication comprises 10 seedlings. Totally, there are 720 seedlings. Experimental design used in progeny test plot of jabon is Randomized Complete Block Design. Breeding strategy used in this plot was subline system with single treeplot. Number of families used are 28 families. Each family comprises 20 blocks that were also functioned as replication. The results showed that there were significant differences in terms of height and diameter among the tested families at all observation ages. Family heritability estimates for height were high at at all observation ages. Family heritability estimates for diameter were high at nursery and moderate after plantation.

Abstract

Anthocepalus cadamba (white jabon) has high economical value for furniture. White jabon forests severely degraded due to intensive exploitation and land conversion. Genetic diversity is one of important consideration to design conservation and improvement strategies. Aim of this study was to access the genetic diversity values within and among population of white jabon. Leaf samples of white jabon were collected from conservation plots originated from West Lombok, Sumbawa, South Sumatera and West Sumatera. Red jabon was included as an outgroup population. Based on 37 polymorphic RAPD loci, the results showed comparable value of genetic diversity between white jabon and red jabon. Number of detected and rare alleles was highest founded in Sumbawa population among the other three populations of white jabon. As consequence, value of expected heterozygosity in the population was highest (HE=0.315). Private allele was only detected in South Sumatera population. Principal coordinate analysis (PCA) showed that integrating between genetic and geographical distance was inconsistent; similar gene resources or human impact might be responsible for this result. The populations that have high value of genetic diversity and private allele are recommended to be selected for the conservation strategies, i.e. Sumbawa and South Sumatera.

Abstract

Merbau (Intsia bijuga) is one of high economic value timbers. Establishment of seed source of merbau is essential tosupply qualified seeds for plantation. Center for Forest Biotechnology and Tree Improvement has established provenance test of merbau at Sumberwringin Research Forest in Bondowoso, East Java. The objectives of this study are to know survival and genetic variation of growth traits in provenance test plot of merbau. This provenance test was designed as Randomized Complete Block Design with single factor of provenance consisted of Halmahera Timur, Waigo, Oransbari, Wasior, Nabire and Seram. Each provenance comprises 3 blocks as replication and 60 treeplots of each block. The result showed high survival rate of all provenances (above 90 %). Moreover, genetic variation of height and stem diameter among provenances was also high. The best provenance for survival, and height for all observation years was Wasior. The best provenance for diameter for all observation years was Halmahera Timur. Meanwhile, provenance having the best value of survival, height and diameter for all observation years was Halmahera Timur. The  provenance having the worst value of height and diameter for all observation years was Seram. Whereas, the worst provenance of survival at 1, 2 and 3 years old were Waigo, Halmahera Timur dan Seram, respectively.
