摘要: 本文运用电子计算机进行了荷花品种的数量分类研究。结果表明: 1. Q型聚类分析有助于揭示品种间的亲缘关系。2. R型聚类分析说明了性状间的生物学距离。3. 主成分分析初步反映了各性状所占的信息比例。Abstract: The present paper deals with the numerical classification of the cultivars of lotus(Nelumbo).1. Results obtained through Q cluster analysis are conductive to the revelation of inter-relationships among the cultivars.2. Results obtained through R cluster analysis indicate the biological distances in the characters.3. Results obtained through principal component analysis (PCA) show the ratio of information possessed by each character.
