摘要/Abstract

摘要： 总结了作物在水分亏缺下产生补偿效应的类型、机制及条件.补偿效应类型可分为生长补偿、生理生化补偿、代谢及产量补偿等;从渗透调节、脱水保护等方面对补偿效应的生化及分子机制作了探讨,并阐明了作物产生补偿效应的生物学基础,指出了进一步研究的方向.

Abstract: In arid and semi-arid regions,the fact that crops suffering water deficit is unavoidable.Many studies indicated that plants have an ability to compensate the adverse effect of drought when the drought is moderate.But,how the compensation effects take place,and what are the physiological and biochemical mechanisms? This paper summarized the types,mechanisms and conditions of compensation effect that crops have under water deficit.The compensation effect is classified into growth compensation,physiological and biochemical compensation,and metabolism and output compensation.The biochemical and molecular mechanisms were discussed in terms of osmotic adjustment and dehydrate protection,and the biological basis of compensation effect was also elucidated.Finally,the direction for further study is pointed out.
