Study on genetic diversity of mangrove plant Aegiceras corniculatum populations in Guangxi
摘要
Abstract
RAPD-PCR markers were used to investigate the genetic diversity and genetic differentiation among 3 pop ulations with different habitats of Aegiceras corniculatum in Guanxi. The results showed that percentage of polymor phic band was 20. 2%,and genetic distances among 3 A. Corniculatum populations were 0. 195>0. 169 and 0. 26,re spectively , and 0. 208 on average. The percentage of polymorphic band and Shonnon's diversity index among individ uals within the same population had the same trend,and each was 37. 28% and 0. 331,20. 93% and 0. 225,19. 32% and 0. 17. A large proportion of genetic variance(62. 3%)of A. Corniculatum was among individuals within popula tion, while only 37. 7% genetic variance was among populations.关键词
