| 摘 要： | 用R聚类分析和主分量分析,定量研究了湖北菱科5种8变种37个形态和生态性状的变异及分类学价值。结果表明,植物体大小变异是形态演化的主要方向之一。形态演化的同时,也发生生态分化。除少数性状例外,形态演化与生态分化在相当程度上是独立的。

| Abstract: | Taxonomic values of 37 morphological and ecological characters of 5 species and 8 variaties of Trapa were evaluated by means of R cluster analysis and principal component analysis(PCA). Results have shown that the sizes of plants have played an important role in the classification of Trapa. It has also been revealed that the variation of plant sizes is one of the main aspects of morphological differentiation. Interspcifie ecological differentiations have also occurred. Except a few characters such as leaf and stem color, however, there are not much indication that morphological differentiations are dependent upon ecological differentiations. |
