中国淫羊藿属植物的数量分类研究(英文)

A numerical taxonomy of the genus Epimedium (Berberidaceae) native to China

研究选择了原产中国17种淫羊藿属(Epimedium)植物41个形态学、细胞学等性状指标,根据种间欧氏距离,利用NTSYS-pc Version 2.10e软件中的UPGMA聚类分析方法和主成分分析方法,首次对该属进行数量分类研究。结果表明:被研究的17个种的各居群在UPGMA聚类中很好的分开。数量分类研究支持Section Diphyllon中的Series Brachycerae的划分。

In the present paper, numerical taxonomy of 56 accessions, belonging to 17 species of ge- nus Epimedium native to China were carried out using 41 morphological and cytological characters. The principal components analysis （PCA） and UPGMA cluster analysis of NTSYS - pc （ Version 2.10e） were performed to analyze the Euclidean distance of the relationship of the species in the genus. Re-suhs indicate that 17 species DiphyUon （native to China）, by the numerical taxonomy. in this study all were se Series Brachycerae in the parated easily in the dendrogram. In Section dendrogram was supported as a distinct groupby the numerical taxonomy.
