Abstract

The anatomical characteristics of eight major wood species planted in Indonesia were investigated to provide valuable information for their effective utilization. The growth-ring boundaries of Damar and Sumatran pine were indistinct. Resin canal was found in Sumatran pine but it was not observed in Damar. Cupressoid pit and taxodioid pit were found in Damar and window-like pit and pinoid pit were observed in Sumatran pine. Tracheid length of Damar and Sumatran pine was shorter than $3,000{\mu}m$. There were uniseriate rays in Damar and Sumatran pine and fusiform ray in Sumatran pine. All the hardwood species observed in this study were diffuse-porous. They had different vessel groups, i.e., solitary pore in Afrika and Simpur Batu, pore cluster in Angsana and mostly 2-4 rows of radial pore multiple in Mahoni. Mindi and Trembesi had mostly 2-3 rows of radial pore multiple with paratracheal parenchyma as aliform and confluent types. Afrika, Mahoni and Simpur Batu showed heterocellular rays which composed of procumbent cells in the body and mostly 1-2 rows of upright and/or square cells in the margin. All ray cells procumbent was observed in Angsana, Mindi and Trembesi. The large rays commonly exceeding 1 mm in height and ray width of 3~6 cells were observed in Simpur Batu. The other five hardwood species showed ray width of 1~3 cells. Vessel number per $mm^2$ of Angsana and Simpur Batu was higher than those of the other hardwood species. The length of wood fiber and tracheid showed a tendency to increase from pith to bark. By IAWA list, fiber length of hardwoods was classified into long in Simpur Batu and short in Angsana and Trembesi.

최근 인도네시아에서 인공조림중인 8수종 목재자원의 효율적 이용방안 모색을 위해 해부학적 특성을 조사하였다. 침엽수종인 Damar와 Sumatran pine의 생장륜은 뚜렷하지 않았고 Sumatran pine은 수지구가 존재하였으나 Damar는 수지구가 관찰되지 않았다. Damar는 편백형과 삼나무형 벽공을 보였고, Sumatran pine은 창상벽공과 소나무형벽공의 분야벽공형태를 보였다. 두 수종 모두 $3,000{\mu}m$ 이하로 다소 짧은 가도관의 길이를 보였고, 방사조직은 주로 단열방사조직으로서 Sumatran pine의 경우 방추형 방사조직이 관찰되었다. 활엽수 수종은 모두 산공재였고 Afrika와 Simpur Batu는 고립관공, Angsana는 집단관공, Mahoni는 2~4열의 방사복합관공, Mindi와 Trembesi에서는 2~3열의 방사복합관공과 익상유조직, 연합익상유조직이 다른 수종에 비해 뚜렷하게 관찰되었다. Afrika, Mahoni와 Simpur Batu는 평복세포와 1~2열의 직립세포로 구성된 이성방사조직이, Angsana, Mindi와 Trembesi는 평복세포로 이루어진 동성방사조직이 관찰되었다. Simpur batu는 높이 1 mm를 초과하는 3~6열의 다열 방사조직 폭을 보였으며, 이외 5개 수종은 1~3열의 방사조직 폭을 보였다. 단위면적($mm^2$)당 관공의 수는 Angsana와 Simpur Batu가 다른 수종에 비해 많았으며 특히 Simpur Batu가 가장 많게 나타났다. 모든 수종의 목섬유길이는 수심부에서 수피로 갈수록 증가하는 경향을 보였으며, Simpur Batu가 가장 긴 섬유의 길이를, Angsana와 Trembesi가 가장 짧은 섬유길이를 나타냈다.
