| Abstract: | The genetic diversity and differentiation of three Chinese Bruguiera gymnorrhiza populations are ex-amined. Expected heterozygosity at species and population levels is 0. 293 and 0. 268, observed heterozygosity is 0. 274 5 and 0.270 5, respectively. The genetic diversity between population is 0. 083 0, which shows that among total heterozygositios, 8. 3 % come from inter - population. Gene now is smooth, which is 3. 34. |
