Genetic Diversity and Population Differentiation of Cephalotaxus mannii Hk.f.Populations

Genetic diversity and population differentiation among 5 Cepha lotaxus mannii Hk.f.populations were investigated using the assay of vertical slab polyacrylamide gel electrophoresis.Cephalotaxus mannii Hk.f.maintained relatively low level of genetic variation with P =0.33, A =1.33, He =0.135 and Ho =0.139.Genetic differentiation (Gst) was low among populations, Gst was 0.123,and the means of genetic identity and genetic distance were 0.9719 and 0.0288 respectively.The greatest differentiation between Mt.Limu population and others may be attributable to the prevalent wind direction in the season of pollination.
