Phenotypic Diversity of Flowers of Xanthocerassorbifolia Bunge in Dingxi Area of Gansu

Abstract

Abstract: 9 phenotypic traits were investigated for 40 Xanthoceras sorbifolia Bunge.Phenotypic variation was studied by using variance analysis and variation coefficient.The results showed that differentiations among various phenotypic traits of flowers were obvious and there had greater variation among different individuals of X.sorbifolia in trial area,and the sequence of variation coefficient of traits was as follows:sterile flower number of top inflorescence(65.16%)>fertile flower number of top inflorescence(45.26%)>length of side inflorescence(32.29%)>length of top inflorescence(29.28%)>sterile flower number of side inflorescence(24.55%)>horizontal diameter of petal(20.22%)>longitudinal diameter petal(11.76%).

Key words: Xanthoceras sorbifolia, inflorescence, phenotypic traits, differentiation
