Advance and Prospect in Regulation Mechanisms of Seed Dormancy and Germination of Rice in China in Recent Years
摘要
Abstract
The dormancy and germination of rice seeds are important agronomic traits to maintain rice yield and quality.Before rice seed harvest,lower dormancy levels easily cause pre-harvest sprouting,resulting in reduced yield and quality.On the other hand,the high degree of dormancy usually leads to a low germination rate and the irregular emergence of rice seeds,which seriously restricts rice's high and stable yield.This paper overall reviewed the research progress of regulation mechanisms of rice seed dormancy and germination in 2020-2023 in China,specifically from the three areas,i.e.,plant hormones(abscisic acid,gibberellin,jasmonic acid,auxin,brassinolide,and the cross talk between different hormones),abiotic stress(low temperature stress,salt stress,flooding stress,heavy metal stress,oxidative stress),and pre-harvest sprouting,briefly introduced the research progress abroad,prospected the research trend and direction,and thus aiming to clarify the genetic characteristics and mechanism of seed dormancy and germination,provide a theoretical basis and elite gene resources for the selection of rice varieties with suitable dormancy level.关键词
