摘　　要：植物繁殖性状间的权衡关系反映了植物在产生子代过程中资源获取与分配的生态策略,这影响植物子代萌发、生长及竞争能力。草地植物具有重要的生产和生态功能。草地植物繁殖性状的生态策略研究发现,营养生长和繁殖、繁殖方式以及植物花性状间存在普遍的权衡关系,而缺乏对植物自身繁殖性状间权衡关系的关注。本文综述了草地植物繁殖特征权衡关系的研究进展,从有性与无性繁殖、花部性状、种子大小和数量,到地下芽库与土壤种子库之间的多层面权衡,发现种群内个体和花序水平性分配方面鲜有关于权衡关系研究,揭示了繁殖体权衡如何塑造植物的繁殖策略和生存适应性的机制。通过深入分析权衡机制在植物生长、种群动态和生态系统多样性中的关键作用,阐述了其在理解全球变化背景下植物生长、繁殖及胁迫响应方面的理论价值,旨在为未来草地植物繁殖性状权衡关系研究提供不同角度的参考。The trade⁃offs among reproductive traits reflect the ecological strategies of resource acquisition and allo⁃cation in plant reproduction,which affects the germination,growth and competitiveness of offsprings.Plants play a crucial role in both productivity and ecological functions in grasslands.The studies on the ecological strategies of reproductive traits in grassland plants have found that there are trade⁃offs between vegetative growth and reproduction,reproductive mode,and floral traits.In contrast,less attention has been paid on the trade⁃offs among reproductive traits.Here,we review the progress of research on trade⁃offs among reproductive traits in grassland plants from the perspectives of sexual and asexual reproduction,floral traits,seed size and number,and trade⁃offs between the un⁃derground bud bank and soil seed bank.Few studies have focused on trade⁃off relationships at the level of individual plants and inflorescences within populations.We revealed how reproductive trade⁃offs shape plant reproductive strat⁃egies and the mechanisms of survival adaptability.Furthermore,by delving into the critical role of trade⁃off mecha⁃nisms in plant growth,population dynamics,and ecosystem diversity,we elucidated their theoretical significance in understanding plant growth,reproduction,and stress responses under the background of global change.This review would provide diverse perspectives for future research on the trade⁃offs of plant reproductive traits in grasslands.
