Review on the non-enzymatic scavenging agent of reactive oxygen species in aged seeds

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.
