Abstract

Flowering intensity, insects visiting flowers and pollinators of S. album were determined in a study conducted in an ex-situ conservation plot, Watusipat, Gunung Kidul, Yogyakarta. Observations were undertaken during flowering season in 2009 and 2010, with an objective to determine the patterns of flowering and flower visiting insects of S. album in this population. In this study site, S. album typically flowers twice a year and reaches a peak on June and November. Flowers are visited by various insects, major in honey bees and ants. Santalum album is predominantly cross pollinated by insects however, low number of fruit set found in an open pollination. Variation of flowering intensity and the degree of self-incompatibility may influence the low number of fruit production in this species.

Abstract

”Decentralization of protected forest management from central to district government has not yet been implemented effectively. This effectiveness depends on many factors that include policy contents and political process or discourse in the policy making process. This study aimsto: 1) analyze the discourse in policy making process of decentralization in the management of protected forests, 2) analyze the actors/networks and their interests and 3) find out policy space for future policy reform. Both quantitative and qualitative approaches were used in the study. The results show that there are three discourses in the policy-making process of decentralized management of protected forests, namely: i) democratic discourse (with story line of externality and accountability, supported by an association forum of Indonesian district government and  decentralization experts); ii) economic discourse (with story line of efficiency, supported by businessmen, Association of Indonesian Provincial Government and World Bank); and iii) democratic and economic discourses. The House of Representatives (DPR) and Ministry of Home Affairs have authorities and capacities to integrate two discourses. Redefining of externality and interdependency can be used as narratives of new policies to improve the policy of decentralized protected forest management.

Abstract

This study investigated the applicability of liquid medium in direct organogenesis of in-vitro culture of Melia azedarach L. Explants were collected from in-vitro multiplication originating from aseptically germinated seedling and from a 48 - years old mature tree. For adventitious shoot differentiation, 2 mm length of excised explants were cultured on liquid medium of MS (Murashige and Skoogs) basal medium supplemented with 28 combinations of hormone BAP (6-benzylaminopurine) and NAA (á- naphthaleneacetic acid). Differentiated shoots were subsequently cultured for shoot elongation in solid medium using MS basal medium supplemented with hormone BAP individually as well as in combinations with NAA. Finally, rooting culture were done using MS medium supplemented with IBA (3  indolebutyric acid). The results showed that the rate of shoot organogenesis of M. azedarach could be obtained through agitated liquid medium culture technique. The combination of hormone BAP 0.1-1 µM and NAA 0.01-0.1 µM are induced more adventitious shoot at a rate of 5 shoots / 2 mm length size of explants are transferring into rooting medium containing IBA 4.92 µM.

Abstract

Comprehensive  tree improvement  program for Acacia mangium has been started since 1992 by establishing  a  series  of  first generation  Seedling  Seed  Orchards  (SSO)  in  Indonesia.  Selection procedures in the first-generation of SSO have completely finished, and subsequently it was continued for second-generation improvement. This paper examines a trend of realized genetic gain as a response of selection practiced in the first-generation SSO. The observation was carried out in three sub-lines of the second-generation SSO (namely Sub-line B, C and D). Parameters recorded included tree height, diameter at breast height (dbh) and stem straightness that were recorded periodically up to 4 years growth. The realized genetic gain was calculated as a percentage of improved plus trees population in the first-generation of  SSO compared to those of  unimproved trees. The results showed that the improved population was consistently better that those of unimproved one until 4 years of age. There were variation in terms of realized genetic gain parameters recorded depending on the sub-lines and ages. The tree height varied from 1.1% to 5%, while dbh and stem straightness were in the ranges of 2.8% to 6.7% and from 1.8% to 8.4%, respectively. Across the three sub-lines, the tree height varied from 2.2% to 3.1%, while dbh and stem straightness were in the ranges of 4.3% to 5.2% and 4.3% to 6%, respectively.  In general, the trend of the realized genetic gains slightly decreased for dbh and tree height with the increasing of ages, while it slightly increased for stem straightness.

Abstract

Tree improvement program for Eucalyptus pellita in Center for Forest Biotechnology and Tree Improvement (CFBTI) was started in 1994. The programs are now beginning their third-generation of breeding which have relied on recurrent selection through establishing open-pollinated seedling seed orchard. Using current technologies, several Industrial Forest Companies in Indonesia are pursuing clonal forestry program with E. pellita to increase plantation productivity using selected clones from comprehensively field testing. This study was aimed to evaluate the early growth and stand volume productivity of selected clones of E. pellita as a part of a breeding program for pulpwood conducted by CFBTI.  Two clonal trials of E. pellita were established in Central Java with two different plot configurations: single tree-plot and multiple tree-plot. Measurement at the trials was done at two years age involving tree height, diameter, stem volume and stand volume. The results of study showed that among the clones were significantly different for all traits accessed. All of tested clones exceeded the control seedling of F-1 generation by 9-50% for height, 10-36% for diameter and 22-137%  for stem volume. Clone repeatability ranged from 0.7-0.9, with corresponding individual ramet repeatability ranged from 0.2-0.4. The outperformed of the best three selected clones in single tree-plot trial was consistent when planted in multiple tree-plot trial with stand volume productivity at given age reached 15 m3/ha.

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

Recently, timber  estate or plantation forest plays an important role on wooden based industries.  However, the  plantation timber  quality is relatively low.  Some treatments  have been developed to improve  its low quality, such as preservation with CCB (Chromate Copper Boron) and impregnation with plastic compounds. This study is to compare the durability of timber treated with  plastic and CCB,  non-treated from plantation forest timber  as well  as from natural  forest. The plantation timber  studied were  jeungjing  (Paraserianthes falcataria), damar  (Agathis sp.), pinus  (Pinus merkusii), and rubberwood (Hevea brasilliensis). Non-treated timbers that usually used for marine construction were ulin (Eusideroxylon zwageri), jati/teak  (Tectona grandis), laban (Vitex pubescens) and merbau  (Instia bijuga). After  6 and 12 months,  the results showed that CCB  preserved  timber  were  more durable  than plastic  impregnated timber  and non- treated timber. Wood samples were mostly attacked by marine borer organisms from the family of  Pholadidae  and Teredinidae. The experiment results revealed the possibility of using those plantation forest timber species for marine construction purposes.
