摘　　要：通过对6年生3个杨树无性系树高、胸径、材积及木材的纤维长度、纤维宽度、纤维的长宽比及木材的基本密度等对比分析,结果表明：3个杨树无性系的木材平均纤维长度为0.960 0 mm,纤维长宽比在50左右,基本密度在0.36-0.41 g/cm3之间,壁腔比在0.28-0.36之间。无性系间在地点（P=0.626 9）、胸径（P=0.086 1）以及材积上表现差异均不显著。综合评价认为江淮1号等3个优良无性系可作为营造纸浆林的品种,符合造纸原料的要求,适合在安徽省不同立地条件下栽植。In this paper a comparative analysis was made on the tree height, DBH, individual tree volume and the wood-fiber length, width, length-width ratio and basic density of the 6-year-old poplar trees of 3 clones. The results showed that the mean wood-fiber length, length-width ratio, basic density and ratio of cell wall to cavity of the 3 poplar clones were 0.960 0 mm, roughly 50, 0.36~0.41 g/cm3 and 0.28-0.36 respectively. There were no significant differences among the sites, DBH and individual tree volume of the 3 clones. A comprehensive evaluation showed that the 3 fine poplar clones including Jianghuai No.1 could be used for pulpwood plantations, meet the requirements for paper-making raw materials and suitable for afforestation in different site conditions in Anhui Province.
