摘  要:
采用数量分类学方法对27个垂丝海棠品种的19个性状进行了聚类分析。R型聚类分析结果表明垂丝海棠品种用于形态分类学研究的多数性状具有相对独立性和稳定性。Q型聚类分析结果表明:枝条直立或下垂应作为垂丝海棠品种分类的第一级标准,花径、花型应作为第二级标准,叶色、花期等应作为第三级标准。

摘  要:
The paper made the cluster analysis on 19 characters of 27 varieties of Malus halliana by means of numerical classification methods.The result of the R cluster analysis is that the most varieties of M halliana which is used in the study of the classification of appearance are independence and stability.According to the Q cluster analysis,the first degree standard which is used to classify the cultivars of M halliana is straight or droop branch,the second is the form and radius of flowers,the third is leaf colors and flower season.
