该研究利用ISSR分子标记,对分布于福建省内5个样地(邵武、建阳、建瓯、周宁和屏南)的61个野钩锥(Castanopsis tibetana)单株的遗传多样性进行了分析,并采用聚类分析方法探讨了它们的遗传关系。结果表明:用10条ISSR引物从61个单株的基因组DNA共扩增出158条带,包含145条多态性条带,多态性条带百分率达91.77%,其中引物UBC817、UBC819与UBC842的多态性条带百分率(PPB)为100.0%。各居群的多态性条带百分率(PPB)、有效等位基因数(Ne)、Nei's基因多样度(H)和Shannon's多样性指数(I)等各遗传指数差异较大,其中各项遗传指标中最高的为邵武居群,而周宁居群则最低。5个居群的基因分化系数和基因流分别为0.1...

Castanopsis tibetana is an evergreen hard wood tree of red Castanopsis, which is one of the excellent commer￣cial tree species. C. tibetana has great development prospect and ecological value in China. In this paper, the genetic di￣versity of 61 individuals of C. tibetana collected from five plots (Shaowu, Jianyang, Jianou, Zhouning and Pingnan) in Fujian Province of China was analyzed by means of inter￣simple sequence repeat( ISSR) marker, and the genetic rela￣tionship among these individuals also was discussed by cluster analysis method. ...
