【摘要】 本文用7属9种铃兰族Tribe convallarieae植物的叶绿体DNA中rbcL基因片段的PCR产物的RFLP结果进行聚类分析。结果表明:开口箭属与蜘蛛抱蛋属关系密切,夏须草属与族内其余各属亲缘关系稍远,与外部器官形态、核型和孢粉学资料所得出的结论基本一致。此外,本文对铃兰属的系统位置也进行了讨论。更多还原

【Abstract】 The evolutionary history of the tribe Convallarieae (s. l. ) is constructed by comparative RFLP of PCR-amplified chloroplast DNA fragment and subsequent phenetic analyses with UPGMA method. The results show that the genus Tupistra and the genus Aspidistra are phylogenetically closely related, and the genus Theropogon may be alien to the other genera of the tribe, supporting the conclusion derived from morphological, karyotypical and palynologictal aspects. In addition, the systematic position of the genus Convallaria is also discussed.更多还原
