Abstract
The aim of this study was to investigate biometrical properties of bark, node and internode chemical components of Bamboo phyllostachys pubescens. The results showed, there were significant difference between fiber length of bark, node and internode; and internode had maximum fiber length and node had minimum fiber length. There were also significant difference between lumen diameter and cell wall thickness; and node had the highest value. In terms of chemical compositions; amount of extractives, lignin and ash of node were more than internode, but there weren’t significant differences at the 95% confidence, while the amount of cellulose of internode was significantly more than node. Slenderness ratio, flexibility ratio and Raunkel ratio were also calculated for bark 93.06, 36.641, 172.916% and for node 46.308, 33.108, 202.035% and for internode 88.151, 31.678, 215.666% respectively. Generally the observations indicated that, according to the characteristics of the fiber of this nonwood plant, it can be recommended to produce pulp and paper.
