Abstract
Anatomical study was done on two species of woods, namely Sawih or Berembang Bukit (Duabanga moluccana Blume) and Terbulan or Sesendok (Endospermum diadenum (Miq. ) Airy Shaw). The objectives were to determine differences between selected anatomical characteristics of both species and their trend in relation to vertical and radial direction. Measurements were done and safranin-stained sections of both species. Among the properties measured were fibre length, fibre diameter, fibre wall thickness, fibre lumen diameter, vessel diameter, number of vessel per mm2, ray height, ray diameter and specific gravity. The data were analysed using two-level nested ANOVA. The overall anatomical properties of both species were significantly different. Two-level nested ANOVA showed that the fibre length of E. diadenum was longer than that of D. moluccana. Fibre wall thickness showed no significance different between both species. For Duabanga moluccana, the fibre length increased with radially from pith to bark. Similar radial trend was also found for fibre wall thickness for species, Endospermum diadenum and Duabanga moluccana, fibre diameter, fibre lumen diameter, vessel diameter and ray diameter of Duabanga moluccana. Measured anatomical vertical trends for both species are patterned differently. Specific gravity of Endospermum diadenum was significantly higher than Duabanga moluccana. Overall, the results of this study showed that Endospermum diadenum has better anatomical properties compare to Duabanga moluccana. This study showed that radial variaton, vertical variation and anatomical characteristics between Duabanga moluccana and Endospermum diadenum timber were dissimilar.
