| 摘 要： | 对湖南省湘西自治州的细叶桢楠进行调查，并选取优良的细叶桢楠单株进行生长性状和材质性状的测定。结果表明：（1）细叶桢楠寿命较长。（2）细叶桢楠基本密度在0.4832～0.6209g／cm^3之间，纤维宽度在26.80—33.85μm之间，纤维长度在1.0130～1.1803mm之间。（3）细叶桢楠基本密度与树龄、胸径和材积呈显著正相关关系，在生产上可以通过培育大径材提高基本密度的数值。

| Abstract: | Based on the investigation of Phoebe zhennan resources in Xiangxi Autonomous Prefecture, Hunan Province, the growth per- formance and wood property of the selected superior individuals were analyzed. The results showed that （ 1 ） Phoebe zhennan had a long life span. （2） The basic density of Phoebe zhennan was 0.483 2 ～ 0.620 9 g/cms, the fiber diameter was 26.80 ～33.85 μm, and the fiber length was l. 013 0 ～ 1.180 3 mm. （3） Basic density was positively correlated with tree-age, DBH and volume, which indicated that wood basic density could be improved by fostering woods with larger DBH. |
