Abstract

Abstract:

Seed dormancy is a self-protection way for plants to adapt to external environments to ensure its survival, reproduction and evolution, which is also directly affect agricultural production. In this paper, the regulation mechanism of rice seed dormancy, including the basics of genetics, respiratory and metabolic pathways, hormones and ecological factors were reviewed. The detection methods of seed dormancy characteristics and its influencing factors such as genetic characteristics, plant endogenous hormone and amylase activity were expounded. Meanwhile, this paper summarized and analyzed the researches on physical and chemical regulation techniques of rice seed dormancy, and the application of some technologies in agricultural production, such as planting management, plume removal, spraying preharvest sprouting inhibitor or dormancy breaking agent. Furthermore, the research direction was discussed in order to provide reference for further research on seed dormancy regulation technology.

Key words: rice seed, dormancy characteristics, genetic characteristics, regulation mechanism, seed dormancy regulation technique
