摘要
果实与种子的形成是相关又不相同的两个过程,在不确定的传粉和母本环境中,常出现果实或种子的"过量分化".败育的花或胚珠具潜在的生殖功能.在那些生殖资源受限的植物上或者以提高后代适合度为选择力时,果实和种子败育是选择性败育,此现象在被子植物中比较普遍,尤其在豆科植物中开展了较多的研究.本文在介绍国际上有关植物选择性败育研究的基础上,重点介绍了豆科植物种子的选择性败育类型及其影响因素,并讨论了植物选择性败育的生态学意义.这为豆科牧草或农作物种子产量研究,以及种子植物选择性败育的生态学研究提供了理论依据.
The formation of fruit and seed are two definitions which are both related and different.'Excessive differentiation'of fruit or seed are often found in the uncertain pollination and maternal environment.Abortive flowers or ovules have potential reproductive function.In those plants,fruit and seed abortion are selective abortion based on limited reproductive resources or the selection pressures to improve the fitness of the offspring.This phenomenon is more common in angiosperms,especially in leguminous plants with more research.We review recent advances in selective abortion research in angiosperms,with emphasis on selective abortion and related influencing factors in leguminous plant.We also discuss the ecological significance of selective abortion.This provides a reference for the study of legume forage or crop seed yield and the ecological study of seed plant selective abortion in angiosperms.
