Study on Variation of Wood Propertiesin Pinus tabulae formis

Wang Shanwu(Lu'an Forest Protection Research Staion, Anhui Province)Shen Xihuan(Forest Resources College, BFU)Wang Shimeng(Department of Forest Products and Engineering, BFU)  
The wood properties including wood density,tracheid length and latewood percentage of 326 sample trees from two nature forest stands and 11 plantations, and the wood properties from 151 trees from open-pollinated progenies originating from 16 plus trees of Pinus tabulaeformis were observed. The results showed that there were no significant differences in the wood properties of samples collected from different directions at the same height. The wood density of samples originating from different stem heights was however, significantly different. Variation of wood density mainly existed among individuals within the populations. It is possible to select fast growing trees with high quality wood. Considerable variations of wood density and tracheid length among and within families were noticed. The heritabili-ties of specific gravity and tracheid length were 0.735 and 0.569 respectively.
