摘要
将数量分类方法应用于蜡梅品种的分类,选取14个形态性状,对45个蜡梅品种进行数量分类研究。结果表明,中被片长度和内被片紫纹是蜡梅品种分类的两个重要性状,笔者提出应以内被片紫纹作为划分品种群的标准。
A quantitative taxonomic study was conducted on cultivars of Chimonanthus praecox using cluster analysis. The selected 14 morphological characters of 45 cultivars were investigated. The results showed the length of the middle whorl of petals and the purple texture of the inner whorl of petals were important characters. In this paper, it was suggested that the purple texture of the inner whorl of petals could be used to divide Chimonanthus praecox cultivar group.
