摘要:

为了探测陇西栽培蒙古黄芪的表型多样性及自然类型,对该地栽培蒙古黄芪的11个主要生物学性状进行了主成分分析和Q型聚类分析. 多元统计分析表明,陇西栽培蒙古黄芪在生物学性状上存在较大的变异,尤其在果荚颜色、种子花纹及茎色等性状上显著分化,形成了红色类型、红荚绿茎类型和绿色类型等3个主要蒙古黄芪自然类型,因而该地栽培的蒙古黄芪是一个复杂的异质群体.

关键词: 蒙古黄芪, 主成分分析, 聚类分析, 自然类型

Abstract:

To detect morphological diversity and morphotypes in Astragalus membranaceus var. mongholicus cultivated in Longxi county, 11 main biological characters of 210 individuals were investigated and subjected to principle component analysis and cluster analysis. Multivariate analyses showed that the tested individuals of A. membranaceus var. mongholicus have been divergent in some biological characters, especially in pod colour, seed maculation, and stem colour, which resulted in 3 main morphotypes, namely R type, RG type, and G type. It is suggested that the population of A. membranaceus var. mongholicus in Longxi county is heterogenous.

Key words: Astragalus membranaceus var. mongholicus, principle component analysis, cluster analysis, morphotype
