摘要: 居群遗传学在珍稀濒危植物保护研究中有着重要的应用价值。本文首先介绍了居群遗传学中的几个重要概念——有效居群大小、近交繁殖、遗传漂变和基因流,然后详细叙述了居群遗传学原理在珍稀濒危植物保护中的应用途径和前景。

AbstractPopulation genetics is of great value in the study on the conservation of rare and endangered plants.The authors introduced some important concepts in population genetics,including effective population size,inbreeding,genetic drift and gene flow,and then proposed some areas in which population genetics can be used for the conservation of rare and endangered plants.
