| 摘 要： | 菊花拥有非常丰富的品种变异,其分类体系众多,所依据的标准不一,对品种分类最具价值的性状尚不清楚。作者在多年大量实地调查的基础上,依据统计学采样方法,选取了400个独本菊品种,对其57个形态学性状进行数据采集和统计分析;通过计算变异系数和R聚类分析,筛选出22个相对稳定的性状。主成分分析发现:影响品种分类的第1主成分主要包含舌状小花数、花瓣长、总苞片基部到花顶部的高度、花瓣形状等花部性状;第2主成分主要为2个花色性状(花瓣表面色彩和花瓣背面色彩);第3主成分主要是筒状花部直径和筒状花长度;第4主成分主要是托叶相关性状。这些结果显示菊花花部性状相对稳定,对品种分类影响较大;其托叶部分也具有一定程度的稳定性,可以作为品种分类的合理补充;而叶部性状稳定性较差,在品种分类中可以作为更次一级的分类依据。

| Abstract: | Chrysanthemum has abundant variation among its cultivars.There are various classification systems according to different criteria and the most valuable characters for their classification have not as yet been found.We collected and analyzed 57 morphological characters from 400 chrysanthemum cultivars which were chosen on the basis of statistical sampling principles.Then 22 stable characters were selected through a uniformity test and R cluster analysis.A principal component analysis showed that the number o... |
