摘　　要：应用数量分类的方法 ,将采自国内 12个省的 37个居群用 31个性状进行 Q、R聚类分析和主成分分析 (PCA) ,探讨了国产菱属植物间的亲缘关系 ,同时对分类性状进行了评价 .结果表明 :国产菱属的37个居群可以划分成细果野菱和野菱两个种 ,栽培类型由于受人为影响较大 ,不能作为种一级来处理 .31个性状中以果体大小的性状最为重要 ,可作为种的划分依据 ,而腰角的有无。populations of Trapa L. from the 12 provinces of China were studied by means of numerical taxonomic methods. The results are as follows: ①Q cluster analysis is shown that 37 populations can be divided into 3 groups. The first group have only one species of T. maximowiczii, the second include other wild types except T. maximowiczii, the third are the cultivated kinds.② result obtained through R cluster analysis is conductive to the relationships among the 31 characters.③ result obtained through principal component analysis (PCA) shows the loading of 37 populations is a unanimous conclusion with Q cluster analysis.④ Finally, 37 populations of Chinese Trapa L. are divided into 2 species based on the characters of the size and shape of nuts (T. maximowiczii and T. incisa complex) . the characters of upper horns and the others may be the foundation of divided varieties.
