酸枣种质资源果实若干性状的多元统计分析
Multivariate Statistic Analysis of Fruit Phenotypic Traits and Quality of Wild Jujube Germplasm Resources
摘要
Abstract
The seven phenotypic traits of fruits of 60 wild jujube germplasm resources were surveyed and statistically analyzed , and it was found that the fruit color and flavor of wild jujube showed a higher genetic diversity .The 13 fruit quality traits of wild ju-jube were studied through statistics and correlation analysis , and we found that single-fruit weight , starch content and titratable acid content had a higher variable coefficient , and there were significant or highly significant correlations among some quality traits of wild jujube fruits.The principal component analysis showed that:among the four main components , the first principal component could reflect single-fruit weight and long diameter of fruits; the second principal component could reflect single-core weight and edible rate;the fourth principal component could reflect the content of soluble sugar , vitamin C and titratable acid .The scores of four prin-cipal components of all wild jujube germplasm resources were calculated , for the sake of providing reference for wild jujube breeding .关键词
