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

Seed deterioration is the process of deteriorated seed in view of viability that has changed its physiological and nutritional content. This paper studies the effect of seed drying and seed storage to the viability and biochemical content of jelutung (Dyera polyphylla (Miq.) Steenis) seeds. Completely Randomized Design was used for different level of seed drying time, i.e. 0, 24, 48, 72, 96 and 120 hours, and Completely Randomized Factorial Design was used for the combination of seed drying treatments of 0, 24, 48, 72, 96 and 120 hours in different rooms for seed storage (ambient room, air conditioned room, refrigerator) with variables of moisture content, germination percentage and nutritional content. Result shows that seed drying and seed storage treatments pursue the change of seed viability and nutritional content of jelutung seed. The period of time in seed drying and seed storage siginificantly influence the moisture content, germination percentage and nutritional composition (lipid, carbohydrate, protein). The longer time of seed drying will effect significantly to the moisture content and germination percentage, increasing the lipid and protein and decreasing carbohydrate. Jelutung seed that was stored in air conditioned room had better viability compared to ambient room and refrigerator.

Abstract

Genetic parameters for early growth of Neolamarckia cadamba, an indigenous species with potential as a source of timber wood, were estimated in open-pollinated provenance–progeny tests conducted at two sites in West Java Province, Indonesia. The experiment was arranged in a randomized complete block design with 12 provenances, 105 families, and five replications in four-tree row plots. Total height and root collar diameter were measured at 18 months of age. Significant differences among provenances and among families within provenances were observed for height and collar diameter at all sites, except for collar diameter among provenances at the Parungpanjang site. In general, the Garut (GSJ) provenance performed better than the Kualakencana (KKP) and Nusa Kambangan (NKJ) provenances at both sites. Evaluation of variance components at the two sites showed that the provenance effects (ranging from 0.5 to 1.7%) contributed more to the total variance than family-within-provenance effects (ranging from 0.4 to 0.6%). Genetic correlations between height and collar diameter were weak to moderate. Heritability estimates were low for all traits at Limbangan, whereas they were moderate at Parungpanjang. Estimated genetic gain for height and diameter based on proportional family selection of 0.30 was 0.13 and 0.18 at Limbangan, and 0.31 and 0.16 at Parungpanjang, respectively. Continued heritability measurement is required to obtain stable values. Stable heritability combined with family selection and within-family selection will improve genetic gain.
