Abstract:
The leaves,fruits and seeds of ten natural populations of A.truncatum in China were selected as experimental materials,and using correlation analysis,cluster analysis and principal component analysis to analyze the phenotypic diversity of A.truncatum populations and their spatial patterns.In order to determine phenotypic variation of A.truncatum populations.The results showed that,the variation coefficient(CV)of phenotype traits of ten A.truncatum areas ranged from 4.65% to 40.34%，and the fruit opening angle(OA) had the largest variation,while bears the mark(BTM) was the most stable traits.Principal component analysis showed that the main variation sources of A.truncatum was fruit>leaf>seed.Correlation analysis of the phenotypic traits revealed that the relationship between fruit and seed was close,and the correlation between leaf-related traits and seeding was not significant.The correlation analysis between geo-ecological factors and phenotypic traits showed that the latitude and longitude had significant effect on fruits and seeds,and the average annual temperature had significantly impact on leaf.The 10 populations of A. truncatum clustered into four groups according to cluster analysis,which did not strictly classify with the geography distance.
