Low-Temperature Germination of Rice Seeds: Research Progress

doi:10.11924/j.issn.1000-6850.casb20200300238

Abstract

Abstract:

The poor germination of rice varieties at low temperature limits the development of direct seeding rice. In order to promote the development of low-temperature resistant rice breeding and cultivate new rice varieties with low-temperature germination ability suitable for direct seeding, this paper outlined the evaluation methods of low-temperature germination ability of rice seeds and summarized the changes of cell membrane properties, reactive oxygen metabolism, energy supply, hormone content and other related physiological metabolism of low-temperature germination in rice. The molecular regulation mechanism of rice seed germination at low temperature was also generalized, including ABA-dependent signal transduction and ABA-independent signal transduction, at the same time, the genetic studies of QTL mapping and genome-wide association analysis (GWAS) related to low-temperature germination in rice were reviewed. On this basis, the existing problems in current research on low-temperature germination of rice were analyzed and suggestions were proposed, aiming to provide a reference for the research on rice low-temperature germination and the cultivation of new varieties.

Key words: rice, seed, low-temperature germination, physiological metabolism, heredity
