摘　　要：通过方差分析和多重比较,测试了杨树新品系秦白杨系列1、2、3号与对照毛白杨无性系30号的物理力学性质和纤维形态特征。结果表明,秦白杨1号的物理力学性质与毛白杨无性系30号接近,且横纹抗压强度、抗弯强度等指标略优于毛白杨无性系30号。秦白杨2号和3号的物理力学性质次于这两者。秦白杨1号、3号和毛白杨无性系30号的纤维长宽比均>43,且秦白杨3号纤维长度最大。综合纤维形态和材性测试结果,秦白杨1、2和3号均可大面积推广,是适宜制造家具等木材工业和造纸工业的优良新种。This paper dealt with the physical and mechanical properties and fiber morphology of new clones of poplar named Qinbaiyang with the comparison group of Populus tomentosa clone No. 30. Variance analysis and LSD analysis showed that the physical and mechanical properties of Qinbaiyang No. 1 were in close with P. tornentosa clone No. 30, even a little bit better in some indicator tests, such as strength perpendicular and flexure strength. Qinbaiyang No. 2 and No. 3 were a little bit inferior to these two. The fiber ratio of the length to width of Qinbaiyang 1,3 and P. Tomentosa clone No. 30 were greater than 43. Qinbaiyang No. 3 showed the longest fiber length. In summary, Qinbaiyang series varieties can be popularized and applied to furniture making and paper industry.
