厚壳桂种群在不同群落中的分子生态研究

Molecular ecology of Cryptocarya chinensis populations in different communities.

使用AFLP(Amplifiedfragmentlengthpolymorphism)方法对南亚热带演替顶级种厚壳桂在 2个不同群落 ,常绿阔叶林和针阔混交林中的遗传分化进行了研究 ,结果表明 ,种群的大部分遗传变异 ( 89.5 5 % )是由于个体与个体之间的差异造成的 ,有 10 .45 %的遗传变异是由于群落的不同造成的 ,其显著性检测为极显著 .

The amplified fragment length polymorphism (AFLP) method was used to analyze two populations of Cryptocarya chinensis , the succession climax species in lower subtropical broadleaved forest, The across two communities of evergreen broadleaved forest and mixed coniferous broadleaved forest. The analysis of molecular variance (AMOVA) indicated that the genetic variation was mostly due to the difference within individuals of the population (89.55%), with high significant genetic variation (10.45%) due to the different communities. The microenvironment of different communities and population biological characteristics resulted in the genetic divergence.
