Abstract: Tsuga longibracteata is a species distributing only in China. This paper deals with some properties of it’s wood, such as specific gravity, width of growth rings, late-wood percentage, shrinkage and swelling of wood, compressive strength parallel and perpendicular to the grain, tensile strength perpendicular to the grain, bending strength and shear strength parallel to the grain, toughness and hardness. The 5 boles experimented on were collected from Fujian province, of which 1369 samples were made.The mean values consisted of three parts: the five different boles, the three difr ferent heights and the total.In this report, regression analyses were made for the variation of percentage of late-wood and various strength with respect to specific gravity and 18 regression equations were given as a result.In regression analyses, the values of strength and specific gravity were determined in the same sample, or they were the mean values of sample board. The results in-dicated that the former is better.
