Abstract:

China is vigorously developing and utilizing coastal saline-alkaline land to boost rice production. Restricted by freshwater resources and water conservancy foundation, coastal saline-alkaline rice production is very susceptible to composite salt-drought stress, which significantly diminishes rice yield and deteriorates rice quality, and seriously restricts the realization of the goal of abundant production and quality improvement of coastal saline-alkaline rice. This paper summarizes the effects of salt damage, drought and its compound stress on the formation of processing quality, appearance quality, cooking flavor quality and nutritional quality of rice, describes the mechanism of its influence on the formation of rice quality from the aspects of osmotic stress, ionic balance, photosynthesis, antioxidant protection, endogenous hormones, carbon and nitrogen metabolism, metabolites, gene regulation, and so on, and proposes a new method to mitigate salt/drought stress in rice, which is based on the selection and breeding of salt-drought-tolerant varieties, and the cultivation and control of the response to salt/drought stress. It puts forward the control measures to alleviate salt/drought stress in rice, and suggests the next step to carry out the research on the physiological mechanism of the formation of rice quality affected by compound salt-drought stress.

Key words: rice, combined salinity-drought stress, salt stress, drought stress, grain quality

摘要:

我国正大力开发利用滨海盐碱地发展水稻生产。然而,受限于淡水资源和水利基础设施,滨海盐碱地水稻生产过程中极易遭受盐-旱复合胁迫,导致水稻产量和稻米品质显著下降,严重制约了滨海盐碱地水稻丰产提质目标的实现。本文系统综述了盐害、干旱及其复合胁迫对水稻加工品质、外观品质、蒸煮食味品质和营养品质的影响,并从渗透胁迫、离子平衡、光合作用、抗氧化保护、内源激素、碳氮代谢、代谢物及基因调控等方面阐明了其影响稻米品质形成的作用机制。此外,本文还从耐盐耐旱品种选育和栽培调控技术等方面提出了减轻水稻盐/干旱胁迫的调控措施,对下一步深入开展盐-旱复合胁迫影响稻米品质形成的生理机制研究提出建议。
