Abstract
The wood anatomical and physical-mechanical p roperties ofDa lberg ia sissoo Roxb. introduced from Nepalp lanting in Yuan J iang in Yunnan Province were studied. Results indicated Dalbergia sissoo was diffuse2porouswood, the form of fiberwas even and in average length 1. 43 mm. The micro fibril angle was 12. 24°. The air2driedand p rofile density were respectively 0. 746 g·cm-3 and 0. 634 g·cm-3 in average. The air2dried and oven2driedof variance shrinkage were 1. 75 and 1. 55 respectively. The comp rehensive quality coefficient of Da lberg ia sissoowas 2 309 ×105 Pa, and a high quality wood for higher levelmaterial.
