Abstract

Forty four clones of Acacia hybrid  propagated from selected stoolplants were tested together with a control of pure species seedling and clone in a clonal test established at Wonogiri, Central Java. The design of clonal test was Incomplete Block Design, which was laid-out as single treeplot of 20 replications with spacing of 3 m x 3 m. Measurements of tree height were conducted at age 12 months. There were significant differences between the clones in height growth. Eleven clones of 44 were more superior than the original population at SSO F1 (Control 4th) which superiority ranging from 1.81-35.35 % and 3 of them were more superior than the pure species (control 1th, control 2th and control 3th) which superiority ranging from 3.51 – 17.28%. Meanhile, clone repeatability for height at age 12 months was, while individual repeatability for height was 0.59 +- 0.1

Abstract

Combination of provenance progeny trial of Acacia mangium from Claudie River-Queensland- Australia was established in Pelaihari, South Kalimantan. The objective of this research is to find variation on diameter, wood specific gravity and fiber lenght between provenance seedlot and family within provenance seedlot in provenance progeny trial of A. mangium on 22 months old.The results showed that the mean of wood specific gravity and was 0.40 and mean of fiber length was 0.89 mm. Variation of diameter, wood specific gravity, and fiber length were significant difference among provenance seedlot or between family within provenance seedlot in the trial. Individual heritability of diameter, wood specific gravity, and fiber length were medium (hi 2=0.49 for diameter; hi 2=0.33 for specific gravity and hi 2=0.39 for fiber length). The results of investigation from this trial indicate that diameter, wood specific gravity, and fiber length are necessary to be used for tree selection to improve growth wood quality in the combination of provenance progeny trial of A. mangium.

Abstract

The first generation of Acacia hybrid between A. mangium and A. auriculiformis potential to be developed for plantation because of its superiority. The superiority of hibrid Acacia were fast growth, straight bole, light branching, more tolerant to pest/disease attack and better wood property than the parent trees. The only way to maintain their superiority is to propagate it vegetatively. The objective of the research was to observed characteristics of hibrid Acacia based on seed viability,sprouting and rooting ability. Materials used in this study were collected seed from control pollination at breeding garden which verified by molecular marker. The result showed that the character of seed viability on hybrid Acacia was still low (48.1%) meanwhile the sprouting and rooting ability were 16.5 ± 0.7 shoots and 78,4% respectively.
