植物对盐碱胁迫的响应

Responses of Plants to Salt-alkali Stress

土地盐碱化是制约农林业生产和生态环境建设的严峻问题。研究盐碱胁迫下植物的抗性效果,为开发利用盐碱化土地及培育优良抗盐碱的植物品种有很重要的意义。本文简要综述了盐碱胁迫下植物的形态、生理、生化方面的响应,以期揭示植物的抗性机理。

Soil salinization has been a severe problem which restricts the production of agro-forestry and the ecological environment improvement. Hence, studying the plant resistance to salt-alkali stress has an important significance upon how to develop and utilize salinized soil and how to produce new varieties which can resist salt-alkali stress. In this article, a summary description is given of plant responses to salt - alkali stress in morphology, physiology and biochemistry, aiming to reveal the mechanism of plant resist- ance to the stress.
