| 摘 要： | 以文冠果花为研究对象,调查了试验区内40株文冠果花的9个表型性状,利用变异系数和方差分析研究了分布区内的变异情况。结果表明,试验区内文冠果花的不同表型性状差异明显,表型性状在不同个体之间存在着较大的变异幅度,其变异系数大小依次为顶花序不孕花数(65.16%)>顶花序孕花数(45.26%)>侧花序长度(32.29%)>顶花序长度(29.28%)>侧花序不孕花数(24.55%)>花瓣横径(20.22%)>花瓣纵径(11.76%)。

| 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%). |
