摘　　要：采用数量分类的方法,将大花君子兰7个品种22个形态学性状分为定量性状、定性多态性状和定性二态性状进行量化处理,探讨了大花君子兰品种数量分类和植物学性状描述的主要特征。结果显示:R型聚类表明所选22个性状具有相对的独立性,Q型聚类将大花君子兰7个品种分为3组;主成分分析选出了18个性状作为鉴别大花君子兰品种及品种描述的重要特征。With seven types of Clivia miniata varieties as materials,twenty-two morphological traits have been investigated and classified into quantitative trait,qualitative polymorphic trait and qualitative dimor-phic trait by numerical classification .The main features of description of botanical traits and numerical classification of Clivia miniata varieties have been explored .R-cluster analysis suggested that the twenty-two selected traits have relative independence .Q-cluster analysis classified the seven types of Clivia miniata varieties into three groups .By principal components analysis,eighteen traits have been selected as important features for identifying Clivia miniata varieties and describing the varieties .
