摘　　要：通过对白花桔梗和紫花桔梗种质资源的地上部性状的调查分析,结果表明:除了白花桔梗种质资源的茎粗平均值大于紫花桔梗种质资源之外,株高、主茎叶数、分枝数、茎叶鲜重等均小于紫花桔梗种质资源的平均值;紫花桔梗种质资源的分枝数和茎叶鲜重全部高于白花桔梗种质资源;紫花桔梗种质资源和白花桔梗种质资源的株高、茎粗和主茎叶数无明显差异。此结果为白花桔梗和紫花桔梗种质资源的合理利用提供了参考依据。Investigated the on above--grotmd traits of white flower platycodon grandiflorum germplasm resources and purple flower platycodon grandiflomm germplasm resources. The results showed that except average of stem diameter was greater, the others average of plant height, main stem leaf number, number of branches, stem and leaf fresh weight for white flower platycodon grandiflorum were less than purple flower platycodon grandiflorum; purple flower platycodon grandiflorum of branch number and Stem and leaf fresh weight of all the above white flower platycodon grandiflorum; but there were no significance differences in plant height, stem diameter and main stem leaf number between them.
