摘要: 在同一栽培条件下,对采集自四川省各地区的22个野生扁穗牛鞭草[Hemarthria. compressa(L. F.)R. Br.]居群的15个形态学性状进行了模糊聚类分析,在置信水平λ=0.8197时将22个居群划分为4个类型,说明四川野生扁穗牛鞭草存在较为丰富的形态多样性,并分别讨论了各类型的主要特点和利用价值。

Abstract: populations of H. compressa(L. F.) R. Br. originated from different habitats in Sichuan province were collected and cultivated in the experimental farm of Sichuan agricultural university with the same cultural method in November of 2002, of which 15 morphological characters were observed and classified with fuzzy cluster analysis. When the confidence level(λ) is 0.8197, 22 populations can be divided into four groups with significant difference from each other. It approves that there is rich morphological diversity of wild populations of H. compressa collected in Sichuan province. The appearance of principal characters and the utilization potential in each group are also discussed in this paper.

Key words: Hemarthria R. Br., population, morphological differentiation, fuzzy cluster
