摘　　要：种子活力是种子播种质量的重要指标,也是种用价值的主要组成部分,它是一个复杂的综合性状,表现为种子快速发芽、耐逆萌发、幼苗快速建成等性状。种子活力与种子发育、成熟、劣变、萌发和处理等环节都密切相关,且受到各种外界环境的影响。本文重点总结了调控种子活力形成、种子快速萌发、种子耐逆萌发、种子幼苗建成等方面的分子机理研究进展,并对今后研究方向进行了展望。Seed vigor is an important index of sowing quality and a major component of seed value.Seed vigor is a complex trait encompassing attributes such as rapid germination,high stress tolerance,and rapid seedling establishment.The regulation of seed vigor is involved in the processes of seed development,seed maturation,seed deterioration,seed germination,and seed treatments,and it is also influenced by various environment factors.In this review,the recent advances on the molecular mechanism of the regulation on the vigor establishment,rapid germination,stress tolerance,and seedling establishment were summarized,as well as the prospects of future research was discussed.
