Abstract

In order to provide scientific foundation for the conservation, development and application of Tetracentron sinense germplasm resources, 10 leaf morphological traits and 7 leaf epidermal micromorphological traits of 161 individuals in 24 populations were investigated, and then the methods such as descriptive statistics, genetic correlation analysis, principal component analysis and cluster analysis were used to discuss the phenotypic diversity of the endangered plant. The coefficient of variation among leaf phenotypic traits indexes varied from 4.21% to 49.23%, and Shannon-wiener diversity indexes varied from 0.82 to 2.07, with an average of 1.80, in which the LLEST was the maximum, and the LBPI was the minimum. Close relationship existed among leaf phenotypic traits. The contribution rate of the first three principal components reached 83.712%, which could respectively represent the distribution of phenotypic traits. Twenty-four populations of T. sinense were clustered into 3 groups when threshold was 15 in Q-clustering analysis. Results showed that the leaf phenotypic diversity of T. sinense was relatively low. Tangjiahe(TJH), Hongkou(HK) and Foping(FP) should be considered as key protection of wild populations.
