新疆杏叶片表型与光合性状多样性分析及综合评价
Analysis of diversity and comprehensive evaluation of leaf phenotypic and photosynthetic traits of apricots in Xinjiang
摘要
Abstract
Taking 46 apricot germplasms from Xinjiang as the research objects,12 leaf morphological indicators and 5 photosynthetic parameters were measured.Diversity analysis and comprehensive evaluation were carried out using coefficient of variation,cluster analysis,principal component analysis and correlation analysis to provide a basis for the protection of apricot resources in Xinjiang and the selection of improved varieties.The results showed that the coefficients of variation of 17 leaf traits ranged from 9.9％to 49.4％,and the variation of photosynthetic traits was higher than that of morphological traits.Cluster analysis divided the germplasms into 3 groups,and the leaf thickness and dry weight of group Ⅰ were significantly higher than those of group Ⅱ and group Ⅲ.Five principal components were extracted by principal component analysis,with a cumulative contribution rate of 84.496％.Through the comprehensive evaluation index,3 apricot germplasm resources from Xinjiang(110,91,105)with specific or excellent comprehensive traits were screened out.Twelve indicators such as the photosynthetic performance index(PIabs)were significantly correlated with the comprehensive score and could be used as important indicators for evaluating apricot germplasm resources in Xinjiang.There is rich genetic variation in the leaf traits of apricots in Xinjiang.The excellent germplasms screened through the comprehensive trait evaluation provide a scientific basis for the drought-resistant breeding and resource utilization of apricot germplasms in Xinjiang.关键词
