摘要
选取 33个形态学性状 ,应用不加权算术平均配对法 ,对收集到的 3种菟丝子的 2 4个居群进行了数值分类学研究 ,结果表明 :(1)日本菟丝子与大花菟丝子亲缘关系较近 ,两者与中国菟丝子之间关系较疏远 ,聚类结果支持Yuncker对菟丝子属的分类处理 ;(2 )日本菟丝子和大花菟丝子种内都存在遗传多样性 ,根据聚类结果将日本菟丝子分成 2个变种 ,将大花菟丝子分成 3个变种。
A numerical taxonomy study of 24 populations of three dodders was studied by choosing 33 morphological characters and using the UPGMA. The result is shown as follows:(1) Cuscuta japonica Choisy is close to C. reflexa Roxb., while C. chinensis Lam. is alienated from them.(2)There are rich genetic both in C. japonica Choisy and in C. reflexa Roxb.. It is suggested that C. japonica Choisy could be divided into two varieties, and C. reflexa Roxb. into three varieties.
