摘要
植物的交配系统在理论上被视为影响种群遗传结构最为显著的因素之一。在具体实践中，指导着遗传育种和濒危植物的保护。本文首先剖析了交配系统及其相关的概念，并简要回顾交配系统研究的历史、重要的理论模型和方法。然后说明交配系统与种群遗传结构的具体关系，进而讨论交配系统在濒危植物进化与适应中的作用。最后说明交配系统的信息在就地与迁地保护中的重要性。
Plant mating system is theoretically considered as a significant factor which has the most apparent effects on population genetic structure.Therefore,it is practically useful in plant breeding and the conservation of endangered species.In this paper,the meaning and definition of mating system was discussed and the past research on mating system was reviewed, including traditional and model methods. The relationship between mating system and genetic structure of population was then discussed in detail. Mating system plays an important role in endangered species evolution and adaptation.Detailed knowledge about mating system is greatly helpful in the conservation and breeding of such species in situ and ex situ.
