Abstract

The heartwood of ebony displayed series of axial and alternating black and paler streaks. Accordingly, ebony from Central Sulawesi was classified in two different streaks patterns i.e. SL (spider web) and batang macis (matches stick). We investigated the chemical properties (holocellulose, cellulose, lignin, extractive content, ash and pH value) of sapwood, intermediate, and heartwood from the different streaks patterns of ebony wood.  The mean value of holocellulose, cellulose, lignin, ethanol-toluena extractive,  hot water extractive, ash contents, and pH value were 76.59±3.02%, 50.62±4.86%, 26.72±3.05%, 9.71± 2.97%, 13.54±1.43%, 0.97±0.32%, 5.56±0.39, respectively.  On the basis of t-test, holocellulose, cellulose, and hotwater soluble contents were differed significantly between the two streaks patterns.  Analysis of variance showed the radial direction also affected significantly on the chemical contents.  The contents of the holocellulose, cellulose, lignin, extractive ethanol-toluen and ash were significantly differed among sapwood, intermediate and heartwood.  The heartwood showed higher levels of cellulose, lignin, ethanol-toluena extractive and ash contents than those of other parts.  On the contrary, the lowest levels of cellulose, lignin, and ash contents and pH value were found in the intermediate wood region.Keywords: chemical properties, Diospyros celebica, radial direction, spider web, streaks pattern

Abstract

Ebony (Diospyros celebica Bakh.) isan endemic species of Sulawesi. The heartwood of ebony is composed of a series of axial and alternating black and paler streaks. Thisstreak pattern determinesof wood quality. Excessive exploitation causes ebony become scarce and has been classified as vulnerable by IUCN and Appendix II by UNEP - WCMC. Currentdistribution, potency (standing stock) and wood quality of each natural habitat of ebony in Sulawesi are not yet known. This study aims to determine the distribution, potency and wood quality on its natural habitat in Sulawesi. Standing stock data obtained with inventory and the results of the previous inventory.  GPS coordinates of each habitat is taken to make a map. Streaks quality class based on ebony factory standard in Palu and Makassar. The results showed that habitat of ebony was naturally found in Districts of Gowa, Maros, Pangkep, Barru, Sidenreng Rappang, Luwu, Luwu Timur (South Sulawesi Province), Mamuju (West Sulawesi Province), Donggala, Parigi Moutong, Poso and Morowali (Central Sulawesi Province).  The highest standing stock was found at Cenrana, Maros which is about 95,05 m3ha-1.  Most of the remaining ebony habitat were found in the protected areas. Wood quality class A and B were found in Sausu and Poso while other areas classified as class C. Key Words:  Ebony Wood,  Endemic Species Of Sulawesi, Strike Quality
