| 摘 要： | 目的:通过对药用菊花种质资源的植物学性状观测、统计和分析,以期为药用菊花的遗传改良和种质资源保护提供依据.方法:采用随机区组田间试验设计,对药用菊花的26个形态性状进行测定,结合主成分分析和聚类分析,对药用菊花种质资源的形态差异进行分析.结果:在调查的26个形态学性状中有17个性状变异系数大于20%,前6个主成分对变异的贡献率达77.14%,通过聚类分析将29份药用菊花种质资源分为2类.结论:药用菊花种质资源间存在较大的形态分化.

| Abstract: | Objective : Botanical characters of germplasm resources of Chrysanthemum morifolium for medicine were observed and compared, which could offer reference for its genetic improvement and germplasm resources protection. Method :Based on the random blocks field experiments design, twenty-six morphological traits were observed. The morphological differences among germplasm resources were compared by principal component analysis and cluster analysis. Result :The coefficient of variation values for 17 of 26 traits indicated a high level of variation (above 20%). Six principal components which accounted for 77.14% of total variance were extracted from the principal component analysis. The 29 germplasm resources could be divided into two clusters. Conclusion :There were large morphological variation among germplasm resources on Ch. morifolium for medicine. |
