摘要
选取了35个主要性状,对30个桂花品种进行数量分类,结果表明:开花季节为桂花品种分类的主要标准,是稳定的,作为一个比较高级分类标准是比较适宜的;花色作为一分类标准亦是可行的;四季桂品种与秋桂类品种最后相聚,反映了四季桂与秋桂关系较远;金桂和丹桂关系较近;支持向其柏等的分类系统 R型分析基本上反映了性状间的相关性,为今后进一步进行性状的取舍和观测提供了定量化的依据
Based on 35 main characters selected from 50 characters, 30 Sweet Osmanthus(Osmanthus fragrans)cultivars were studied in the paper. Following results were obtained: The bloom color and blooming season are of genetic stability. It can be used as higher criteria of classification. Fragrans Division cultivars and Autumn Division cultivars are clustered lastly,which the both means that are more different. Thunbergii Group and Fragrans Group are more similar. The classification system of Xiang Qi-bai etc. is supported by this study. The results of R cluster analysis reflect the relations among these characters by and large. It offers us quantitative basis for further selection and observition of characters.The relations between bloom color and other characters,had been studied by stepwise regression and correlation analysis .
