摘要:

盐碱土壤对水稻不同生长发育时期均形成盐胁迫,进而导致水稻产量降低。耐盐水稻选育是提高水稻产量的有效途径。本文分析了盐胁迫对水稻不同发育时期农艺性状的影响,并从渗透调节、离子应答、激素调控和活性氧清除四个方面综述了近年来水稻耐盐分子机制的研究进展。最后,本文总结了水稻耐盐育种现状,并对耐盐水稻新品种的选育和推广进行了展望。

关键词: 水稻, 盐胁迫, 渗透调节, 离子应答, 耐盐育种

Abstract:

Saline-alkali soil hinders the growth and development of rice at different stages, resulting in the decrease of rice yield. Salt-tolerant rice breeding is an effective way to increase rice yield. In this paper, the effects of salt stress on agronomic traits at different rice developmental stages were reviewed, and the recent research progress in molecular mechanism of salt tolerance in rice was summarized from four aspects: osmotic regulation, ion response, hormone regulation and active oxygen scavenging. Finally, the breeding status of salt-tolerance rice was summarized, and breeding prospects and promotion of new salt-tolerant rice varieties were discussed.

Key words: rice, salt stress, osmotic regulation, ion response, salt-tolerant rice breeding
