Abstract:Fiber morphology, tissue measurements, cellulose content and basic density of bamboo wood of Phyllostachys heterocycla var pubescens were determined. The variations in the bamboo wood properties related to age, diameter at breast height (DBH), positions in culm from inner to outer and base to top, internode from lower to upper and node. The fiber length, was determined mainly by posidons in culm and internode, and not by age and DBH. The tissue measurements related to DBH, not to age, but cellulose contents and bisic densities all related to age, DBH and positions in culm. Judging from the variation in bamboo wood properties, small culm was superior to big culm in management when the bamboo wood used as a material of paper waking.
