禾本科植物生殖生态学研究进展

植物种群生殖生态学是由生殖生物学和生态学相互交叉而形成的一个新兴边缘学科,它主要研究一定时空内植物种群的生殖活动与环境因子间的相互作用关系及其规律.禾本科是单子叶植物中的一个大科,也是在全球分布最广的家族,该科有近700属,约10 000种,遍布全世界.在广泛查阅了国内外相关文献的基础上,对禾本科植物种子库动态、种子萌发的表型可塑性、性系统、生殖分配与生活史对策等几个重要研究领域的成果,进行了比较全面的综述,以期为今后禾本科植物生殖生态学理论及方法的研究提供借鉴.

Advance in the Researches of the Reproductive Ecology of Poaceae

Plant population reproductive ecology is a new and interdisciplinary subject,and consists of reproductive biology and reproductive ecology.It mainly studies the interaction and rule between reproductive activity of plant population and environmental factor in certain time and space.Poaceae is an important and large family in monocotyledon plants,and is one of the largest families and widely grows all over the world.It has about 700 genera,10,000 species.The article,based on literature research,summarizes systematically the achievements in the seed bank trend,phenotypic plasticity of seed germination,breeding system,reproductive allocation and life history strategies of Poaceae.The author expects to provide reference for further research of the theory and method of Poaceae reproductive ecology.
