摘要
利用 1 3个 1 0 mer的随机引物对中国泡桐属的 7个种进行了 RAPD分析 ,对扩增形成的谱带进行了对比 ,发现 7个种间存在较丰富的多态性带纹。经用 UPGMA法聚类结果说明可把研究的 7个种分成 2个类群。其中白花泡桐与川泡桐亲缘关系最近 ,二者与揪叶泡桐、南方泡桐、山明泡桐归为 1个类群。毛泡桐与兰考泡桐亲缘关系也较近 ,二者在系统演化上比较原始 ,归为 1个类群。
The genomic DNA of seven species in Paulownia was amplified with 13 primers of 10 mer length. Abundant polymorphic DNA makers were detected among seven species, when compared the bands amplified. The cluster analysis with UPGMA suggested that the seven species studied belong to two lineages. Of which, the relationship between P. fortunei(Seem.)Hemsl. and P. fargesii Franch. is the closest. These two species, along with P. australis Gong Tong and P. lamprophylla, belong to one clade, P. tomentosa(Thunb.)Steud. and P. elongata S. Y. Hu have closer relationship, which are relatively primitive, belong to the other clade.
