摘 要:
选取30个主要性状,对薄荷属6个种38个居群进行了数量分类研究。Q型聚类分析结果表明,叶的平或皱是较稳定的,可以作为薄荷属植物分类的主要标准。按照“欧氏距离远近”原则,Q型聚类分析可以比较理想地将38个居群在L3=0.618水平上分为5个系,即日本薄荷系、灰薄荷系、薄荷系、唇萼薄荷系、椒样薄荷系,其中日本薄荷系又可分为日本薄荷亚系和皱叶留兰香亚系,椒样薄荷系又可分为椒样薄荷亚系与留兰香亚系。R型聚类分析基本上能反映性状间的相关性,可以为今后进一步进行性状的取舍和观测提供定量化的依据。[著者文摘]

Abstract:
Based on 30 main characters, 38 populations belonging to 6 species of Mentha L. were numerically classified. The Q cluster analysis results showed that the flatness or crinkle of leaf was genetic stabile, which could be used as major classification criteria of Mentha L.. According to the principle of ＂Europe distance＂, 38 populations were clustered into 5 series by Q cluster analysis at the level of L3=0.618, which were M. arvensis, M. vegans, M. haplocalyx, .M. pulegium. and M. piperita. Among them, Ser. M. arvensis could be divided into Subser. M. arvensis and Subser. M. crispata. And Ser. M. piperita could be divided into Subser. M. piperita and Subser. M. spicata. The results of R cluster analysis showed the correlation among these characters, which offered references for the further character selection and observation in further research work.[著者文摘]
