Potensi dan Karateristik Ekologi Provenansi Eboni (Diospyros Celebica Bakh) untuk Pemuliaan dan Konservasi Genetik

Forest as a natural resource in Indonesia involves high biological diversity. In South Sulawesi, ebony wood is one of endemic and typical natural resources and its existence have placed Indonesia as the producer for the wood with highest economic value. The high economic potency of ebony wood has caused an intensive exploitation of ebony from its natural habitat.. One of factors causing the degradation was the existence of uncontrolled harvesting activities which were not accompanied by rehabilitation efforts. One effort, which can be carried out to anticipate the progressive destructive condition of the ebony in its natural habitat, is by developing and implementing tree breeding as well as genetic conservation systems. This research was addressed to identify the ecological conditions of various habitats or provenances of ebony. Ecological characteristics observed in the current study were the potencies of volume, regeneration or density, and environmental conditions covering four different provenances (Maros, Barru, Sidrap, and Malili). Data were collected by applying random sampling method in plots and field measurement.Research results indicate that the standing stock of different provenances varied from 2.25 – 6.86 m3/ha in volume with the density of 0.8 – 2.16 trees/plot, 2.54 – 6.3 poles/plot, 4.79 – 9.72 saplings/plot, and 90.54 – 139.86 seedlings/plot. The research results show that the existing volume and density of ebony belong to the low category compared to the natural condition.

POTENSI DAN PERMUDAAN TEGAKAN ALAM EBONI (Diospyros celebica Bakh.) DI AREAL HPH PT. INHUTANI I MAMUJU

The intensive use of Eboni has caused a decrease of its natural population which has also contributed to the future loss of genetic potencies. Preservation efforts could only be conducted if the actual potencies of the stand and its environmental conditions were recognized. A study on stand and regeneration potencies as well as its soil characteristics is needed as a basic in management aplication for the increase of genetic potencies. This study used a systematic sampling survey method and laboratory analysis. The study aims to identify tree potencies and regeneration of Eboni Makassar as well as its soil characteristics under the stand. The results are expected to provide a description on Eboni Makassar potencies and its management efforts. It was found from the study that the potency of Eboni was 5.013 m3/ha with minimum and maximum estimated volumes of 3.163 m3/ha and 6.863 m3/ha, respectively. Eboni was naturally regenerated better in >40% slope category. Keywords: Eboni, Potencies and Regeneration, Various Slop

PRODUKSI POLONG DAN BIJI TANAMAN GAMAL (Glirisidia sepium) DARI BERBAGAI PROVENANSI DENGAN PEMUPUKAN NPK

The productivity of forest natural resources is now decreasing and therefore rehabilitation efforts is urgently needed. Breeding of forest plant is the best solution to increase forest productivity in both quantity and quality. The biological reproduction can be conducted through seed production with fertilization. This research was aimed at determining the effect of fertilizing treatments on pod and seed production of different Glirisidia sepium provenances to find out the best provenance and best fertilizer dosage. Fertilization treatments showed a significant effect on the pod and seed production. On the other hand, the provenance and its interaction with fertilizing did not show any significant effects on the pod and seed production. The best performance was found on the fertilization treatment of 500 g resulting in the average production of 1,288 pods and 27,621 seeds/tree.
