摘要
综述了植物有性繁育系统研究中的以下方面:1)从花及花序的设计及展示、性器官的表达、雌雄蕊的运动及随环境变化等方面概述传粉模式的多样性研究;2)植物通过近交来确保繁殖的成功及近交有害性研究;3)异交植物可进行自交,而自交植物也可进行异交,这种混合交配系统的时空动态、维持机理以及进化趋势的研究动态;4)一些分子标记在植物的繁育系统研究中的应用.
In this paper, we give an overview of recent studies of plant breeding systems and address the following four aspects. First, we summarize the studies of the diversity of pollina- tion in floral morphology, the design and display of flowers and inflorescence, the expression of sexual organs, the movement of pistils and stamens and their environment adaptation. Second, we address the studies on the effects of inbreeding, the purpose of which is to ensure the breeding, and hazardousness of inbreeding. Third, Cross pollinated plants can selfing reproduction and vice versa, spatial and dynamic patterns of the mixed mating system and their maintenance mechanisms and evolutionary trends. Fourth, some molecular markers were applied in plant breeding system research.
