| 摘 要： | 调查了６个泡桐无性系的１２个树冠结构因子，并对９个因子进行了主因子分析，结果表明，将９个因子结合为２个主因子，可以包含９０．５％的树冠信息，并认为通过树冠结构来选择抗风无性素是可行的，理想的抗风无性系应是一级侧枝多而较细，新梢夹角较小，树冠较高的细枝塔形结构。

| Abstract: | characteristics of Paulownia crown structure of 6 paulownia clones were investigated, and principal component analyeis was adapted to analyse these clone's crown structure according to 9 extremely different characteristics.The result showed that these charateristics could be classified as two principal components of which accumulative duty rate reached 90.7%.It is feasible to select wind-resistance clone through crown structure.The idedl clone with wind-resistance should have a crown of slender-branches and tower-shaped structure,with more and much slender first ord.Branches,smaller angle of the tip,bigger relative hight rate of crown to the tree |

| Keywords: | Paulownia wind-resistance structure of crown |
