| 摘 要： | 对52个大丽花品种的20个形态学特征进行Q型聚类分析。结果表明:株高应作为大丽花分类的一级标准,依此标准可将大丽花分为两大类;花径应作为大丽花分类的二级标准;叶片大小、花瓣大小和花瓣多少作为大丽花品种分类的三级标准。

| Abstract: | Q-cluster analysis was used to study the 20 characteristics of 52 dahlia cultivars.The results showed that plant height should be served as the first classification criteria,and based on it,the dahlia cultivars could be grouped into two categories.Flower diameter should be served as the second classification criteria,while size of leaves,size of petal and amount of petal should be the third one. |
