Principal Component Analysis and Cluster Analysis of Quantitative Characters of Xanthoceras sorbi folia
摘要
Abstract
Principal component analysis and cluster analysis were conducted on 12 quantitative characters of Xanthoceras sorbifolia by using the statistical software DPS. The results indicated that the additive contributing rates of the first five principal components amounted to 70. 26%. According to the effect of each character on principal component and the composition of main indices, 12 biological characters could be divided into 5 groups: tree form , leaf form, fruit shape, inflorescence, and comprehensive factors. According to the result in cluster analysis, the 12 quantitative characters were divided into 6 groups. The two analyses revealed the influences of these factors on the biology of X. sorbifolia.关键词
