| Abstract: | By the principal component analysis of the leaf characteristc of fourteen Paulownia clones inthe nursery,the eresults show the leaf area and shape are the main factors of differences in theleaf characteristic of Paulownia clones in the seedling stage. They can represent 87%informa-tions in leaf characteristic used as the principal component.Therefore ,they may be consulted asthe main factors when we select the PauIewnia clones in the seedling stage. |
