Abstract:

The problem of soil salinization is becoming more and more serious in China. The saline-alkali land within the red line of cultivated land is about 9.3×106 hm2. Salt stress is one of the main abiotic stresses that restrict grain production. Rice is a pioneer crop in saline-alkali land improvement. It is of great significance to understand the response of rice to salt stress comprehensively. The effects of salt stress on growth, yield and quality of rice were reviewed. The physiological mechanism of salt stress affecting the growth and development of rice was discussed at the physiological level such as osmotic regulation, ion balance and gene fronts. The regulation measures to reduce salt stress in rice were put forward, as well as the prospects and suggestions for further research on salt stress in rice.

Key words: rice, salt stress, growth and development, physiology and biochemistry, molecular mechanism

摘要:

我国土壤盐渍化问题日趋严重,在耕地红线内的盐碱地约有9.3×106hm2,盐胁迫是制约粮食生产的主要非生物胁迫因子之一。水稻是盐碱地改良的先锋作物,全面深入了解水稻对盐胁迫的响应,对盐碱地水稻生产具有重要意义。本文概述了盐胁迫对水稻生长发育、产量和品质形成的影响;从渗透调节、离子平衡等生理层面以及基因层面阐述盐胁迫影响水稻生长发育的生理机制;总结了减轻水稻盐胁迫的调控措施;对今后深入开展水稻盐逆境的研究进行展望并提出建议。
