Primary study on genetic variation and genetic diversity among Castanopsis eyrei populations based on inter-simple sequence repeat(ISSR) markers(甜槠种群遗传多样性的简单重复序列区间初步分析)

应用简单重复序列区间(ISSR)分子标记方法对甜槠种群的遗传多样性和遣传分化进行了初步研究.从100个引物中筛选出12个用于正式扩增的ISSR引物，在9个种群179个个体中共检测到202个位点，其中198个是多态位点，多态位点百分率（P）为98.02%.各种群多态位点百分率在60.40%~70.30%，平均为65.29%.甜槠物种水平的Shannon信息指数（I）为0.532 2、Nei指数(h)为0.359 7.各种群I平均为0.363 5、h平均为0.246 8. AMOVA分子差异分析表明，65.96%的变异存在于种群内，34.04%的变异存在于种群间，种群间的基因分化系数(GST)为0...
