Abstract:Anatomical, physical and strength properties of 4-year-old Schizostachyum brachycladum (Buluh lemang) with nodes and internodes, and the trends in these properties along the bamboo culm height were evaluated. The results showed that the fiber morphology, vascular bundle size, moisture content, radial, longitudinal and tangential shrinkage from green to oven-dry decreased from the basal portions towards the top of the bamboo culm, both in the nodes and internodes. On the other hand, the opposite trend was observed in density, modulus of rupture (MOR), modulus of elasticity (MOE), and the percentage of the vascular bundle. Higher mean value of density; and vascular bundle size, and percentage was found at the node, rather than at the internode, portions. While, internodal fiber morphology, moisture content, radial, longitudinal and tangential shrinkage, MOR, and MOE exhibited higher mean values than the nodal parts. These findings lead to the conclusion that presence of nodes in S.brachycladum resulted to low strength and affects the end product.

Keywords:Anatomical properties, physical properties, strength properties, density, vascular bundle
