摘要: 对我国泡桐属15 个植物种类作了叶绿体DNA 的RFLP 分析, 根据估算的相似系数, 用平均链锁聚类方法构建树状图, 结果可将研究材料分为南方泡桐组、毛泡桐组和白花泡桐组。种间相似系数多在0.70 以上, 说明各种类间亲缘关系较近, 尤其是台湾泡桐和海岛泡桐, 相似系数接近1.00。最后讨论了一些泡桐种类的分类问题。

Abstract: RFLPs (Restriction Fragment Length Polymorphisms) was used to analysis chloroplast DNA of 15 paulownia species. Based on the estimated values of genetic distance, the dendrogram was constructed using UPGMA (Unweighted pair group method of arithmetic clustering), and three groups can be classified. Since most of the values of genetic distance are over 0.70, especially for P. taiwaniana Hu et chang and P. kawakamii Ito, which is 1.00, close relationship among the species could be concluded. At the end of this paper, the taxonomy for some of the paulownia species was discussed.
