摘　　要：对12年生5个毛白杨优良无性系(另1个作对照)胸高处木材的基本密度和纤维形态进行了测定分析.结果表明:4年生以上毛白杨优良无性系木材材质指标满足造纸要求,适合作纤维原料,并优于对照,可以进行区域推广.Wood basic density and fiber morphological features in the breast-height position for512-year-old excellent clones of Populus tomentosa Carr.(1CK)were measured and analyzed in this paper.The results showed that the wood of5excellent clones whose ages were higher than4years old could be used as pulp and fiber raw material;and their wood properties were better than those of CK,so5excellent clones might be spread regionally.

关 键 词：毛白杨 木材性质 基本密度 纤维形态
