dc.description.abstract采用垂直板型聚丙烯酰胺凝胶电泳测定了华东地区6个青冈(CyClObAlAnOPSISglAuCA(THunb.)OErST.)种群的遗传多样性和遗传分化程度以及基因流。青冈种和种群水平都维持有较高的遗传多样性,期望杂合度分别为0.2252和0.2126,观察杂合度分别为0.1661和0.1771。种群间的遗传分化程度较低,分化度仅为5.6%,种群间的遗传一致度和遗传距离的均值分别为0.9729和0.0276。种群间的分化时间为1.4~27万年。基因流分别为4.21和20.49。
dc.description.abstractGenetic diversity, genetic diFFerentiation and gene Flow among 6 Cydobalanopsis glauca (Thunb.) Oerst.populations in East China were investigated using the assay of vertical slab poly-aery lamide gel electrophoresis.C.glauca maintained relatively high level of genetic variation as compared with the average plant species.Expected heterozygosity at species and population level was 0.225 2 and 0.221 6 respectively, and observed heterozygosity were 0.166 1 and 0.177 1 respectively.Genetic diFFerentiation ( GST) was low among populations.GST was 5.6% , and the means of genetic identity and genetic distance were 0.972 9 and 0.027 6 respectively.The divergence times among populations were From 14000 to 270000 years.The gene Flow were 4.21 and 20.49 respectively .
