| 摘 要： | 多性状生长性状间相关表明,6个变量之间具有高度的遗传相关性,均达到极显著水平,相关系数变幅在0.710212～0.999434;通径分析表明:对材积起首要作用的树高和胸径均具有直接的正作用;逐步回归表明:树高和胸径对单株材积贡献最大,决定系数0.97828,可作为杨树遗传改良主要选择性状.

| Abstract: | Correlation analysis on growth straits of new poplar varieties show us: correlation between six different growth traits are highly correlated,which's correlation coefficient varies in the range between 0.710 212 and 0.999 434.The height and DBH were prevalent factors indicated by path analysis,which influence the volume of a tree positively;stepwise regression shows that height and DBH contributes highly to the volume of a tree,coefficient of determination was up to 0.978 28. |
