中国菊属植物部分种的数量分类研究

该文运用数量分类学方法对中国菊属植物２８个分类单位进行了系统进化与亲缘关系研究。Ｑ型聚类结果表明：毛华菊（Ｄ，ｖｅｓｔｉｔｕｍ）与菊花亲缘关系最近，野菊（Ｄ．ｉｎｄｉｃｕｍ）次之，紫花野菊（Ｄ，ｚａｗａｄｓｋｉｉ）较远，Ｒ型聚类分析结果表明菊属植物用于形态分类学研究的多数性状具有相对独立性。在此基础上，作者讨论了中国栽培菊花起源的若干问题。

Study on Numerical Taxonomy of Some Chinese species of Dedranthema(DC)Des Moul.

Twenty-eight operational taxonomic units(OTUs)of Dendranthema (DC)DesMoul. from China were studied by means of numerical taxonomic methods,so as to under- stand genetic relationship of them.The result obtained throug Q cluster analysis is anunanimous conclusion with classical classmcation and shows that D.vestitum is most close toD.×grandiflorum,D. indicum is less close to it and D. zawadskii is a little far to it.Resultsobtained through R cluster analysis indicate that most of the characters used for classificationare relatively independent.The authors also discussed the genesis process of cultivatedchrysantliemum.
