摘要: 应用随机扩增多态DNA(RAPD)标记方法检测了广东南昆山和车八岭、广西靖西和海南霸王岭等4个观光木种群的遗传多样性。利用45个10聚寡核苷酸引物共检测出224个位点,其中多态位点175个,占78.13%,4个种群的遗传多态位点百分率分别为47.89%(海南)、53.96%(靖西)、55.00%(车八岭)和56.35%(南昆山)。观光木的遗传多样性分析结果显示,Shannon 指数为0.3565,其中36.58%来自种群间, 63.42%来自种群内; Nei指数为0.2597,种群间的遗传分化系数(GST

Abstract: Genetic diversity of four populations of Tsoongiodendron odorum, Nankunshan and Chebaling of Guangdong Province, Jingxi of Guangxi, and Bawangling of Hainan Province was examined by Random Amplified Polymorphic DNA (RAPD). A total of 224 sites were detect
