摘要
通过对毛竹（Ｐｈｙｌｌｏｓｔａｃｈｙｓｈｅｔｅｒｏｃｙｃｌａｖａｒ．ｐｕｂｅｓｃｅｎｓ）材纤维形态、组织比量、纤维素含量和基本密度的分析测定，研究了不同年龄、不同胸径、竹秆不同部位材性性状的变异特点结果表明：竹材纤维长度主要受竹秆部位的影响，与年龄和胸径无显著相关；组织比量与年龄无显著相关，与胸径有一定相关；纤维素含量和基本密度与年龄、胸径、竹秆部位均有关系。从材性变异特点来看，经营培育小径级毛竹对制浆造纸更有利。
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.
