摘要
以果实形态特征和生长特性等８个指标为基础，运用主成分分析和系统聚类的方法，对取自河南的３１个枣品种进行了数量分类研究。这些品种被分为４个类群，其中包括６个亚类，与传统的分类结果基本一致。
A quantitative
taxonomic study was conducted on jujube cultivars,Zizyphus ju ju-ba,in Henan Province,using
principal component analysis and cluster analysis.Thirty one culti-vars grown in different localities
were clustered into four groups which were further divided intosix subgroups,according to the fruit
form and the growth habit. The classification thus set up hasembodied many improvements on
traditional classifications.
