Physical and chemical properties of wood are important factors that influence the usability of wood-based products. This study focused on the fast-growing plant species Batai (Paraserianthes falcataria), which has a diameter at breast height ranging from 50 to 70 cm. Tree trunks were cut into three portions (bottom, middle, and top) and partitioned into near pith, intermediate and near bark. Sampling for physical and chemical analysis were performed in accordance with the Pulp and Paper Technical Association Industry USA (TAPPI) T 208 om-94 standards (1996). Statistical analysis of this study revealed that tree portion and radial position have a significant impact on physical properties. The chemical properties of the tree do not differ significantly from the bottom to the top. The bottom has the highest specific gravity, followed by the middle and top. The moisture content increases from the bottom to the top. Cold and hot water, alcohol toluene, ash content, 1% NaOH extract solubility, lignin and holocellulose content were found to differ significantly between the top, middle, and bottom of the tree. Finally, physical and chemical properties of tree portion and parts were found to be significantly affected. © The Authors, published by EDP Sciences.
