摘要
为选择生长速度快、材性表现较好的大青杨优良无性系,本文以14年生8个大青杨无性系为研究对象,采用方差分析、多重比较和主成分分析法对生长性状和材性性状进行综合分析。结果显示:各性状无性系内存在一定程度的变异,但变异幅度不大,变异系数相对较小。生长与材性性状无性系间差异均达到显著水平,为大青杨优良无性系的选择提供较好的基础。通过综合比较与分析,最终选择银山2、银山19、松江36为大青杨优良无性系,对今后大青杨速生优质工业用材林的建设具有积极意义。
In order to select the superior clones with fast growth rate and good wood properties, we took eight 14-year-old Populus ussuriensis clones as research subjects. Variance analysis, multiple comparison and principal component analysis were used to analyze the growth trait and wood properties. The results showed that there were some variations in the traits of clones, but the variation range was small and the coefficient of variation was relatively small. The differences between the clones of growth and wood properties reached a significant level, which provided a good basis for the selection of superior clones. Through comprehensive comparison and analysis, Yinshan 2, Yinshan 19 and Songjiang 36 were selected as the superior clones, which is of positive significance for the construction of fast-growing and high-quality industrial timber forest in the future.
