Effects of Planting Density on Wood Anatomical Properties of Populus×xiaohei

REN Hai-qing; LIU Xing-e; JIANG Ze-hui; WANG You-hong; YU Hua-qiang

The effects of different planting densities(1 000,500,250 trees·hm-2)on anatomical properties of Populus×xiaohei were studied in Shuozhou County,Shanxi Province.The results indicated that the effects of planting densities on fiber width,double wall thickness,vessel ratio,fiber wall ratio,vessel number,vessel tangential diameter were highly significant,and that on ratio of wall to lumen was significant,but for the fiber length,ratio of length to width,tissue ratio of fibers and rays were not significant.The planting densities had certain effects on the radial variation of fiber properties.The results showed an initially rapid and then gentle increase of fiber length and width,fiber wall thickness and ratio of length to width from pith to outward,while ratio of fiber wall to lumen gradually decreased and then tended to stable.
