摘　　要：种子老化是影响种子贮藏的关键问题。活性氧(reactive oxygen species,ROS)非酶促清除剂能延缓种子的老化,但其含量会因种子老化而下降。因此,合理添加ROS非酶促清除剂协助其内部酶系统共同清除种子内ROS,抑制种子的老化,从而延长种子的贮藏寿命,这将成为种质资源迁地保存研究的一个必然发展趋势。本文重点综述了ROS非酶促清除剂的种类及其对种子老化过程的影响,并系统分析了ROS非酶促清除剂在种子老化过程中的研究现状、存在问题及其研究前景,以期为研究种子老化过程中ROS非酶促清除剂的作用机理提供理论基础。Seed ageing was the pivotal problem to influence their storage,which could be delayed by the non-enzymatic scavenging agents of reactive oxygen species（ROS）.However,the content of non-enzymatic scavenging agents reduced during seed ageing.Therefore,it was necessary that non-enzymatic scavenging agents were applied to extend the life span in seeds by eliminating ROS during storage,which would be an inevitable development tendency in ex-situ conservation of germplasm resources.This papermainly reviewed the types and their influences of non-enzymatic scavenging agents on aged seeds,and systematically analyzed their research status,existing problems,and future prospects during seed ageing.This paper might provide a theoretical foundation to study the mechanism of non-enzymatic scavenging agents during seed ageing.
