摘要/Abstract

摘要： 使用AFLP(Amplified fragment length polymorphism)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(89.55%)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.这种结果是由于群落的微环境不同和种群生物学特性造成的

关键词: 厚壳桂, AFLP, 遗传分化, 群落, 种群

Abstract: 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.

Key words: Cryptocarya chinensis, AFLP, Genetic variation, Community, Population
