Abstract
This paper studies the anatomical construction and physical-mechanical properties of Dalbergia sissoo Roxb introduced from Nepal planting in Yuan Jiang in Yunnan Province. Results indicated: Dalbergia sissoo is diffuse-porous wood and the form of its fiber is even with an average length of 1.43mm。The micro fibril angle is 12.24°.The air-dried and profile density are respectively 0.746 g/cm3 and 0.634 g/cm3, which are normal. The air-dried and oven-dried of variance shrinkage are 1.75 and 1.55 respectively. The comprehensive quality coefficient of Dalbergia sissoo is 2309×105 Pa, which is a high quality wood for higher level material. The comprehensive study shows that human breeding Dalbergia sissoo owns elevating quality.
