摘要
干旱胁迫能够明显影响植物光合、代谢、渗透调节等相关生理过程,进而影响植物经济性状指标。外源脱落酸能够缓解干旱对植物生长发育的影响。本研究阐述了外源脱落酸提高作物抗旱性的生理机制,介绍了外源脱落酸对光合生理的调控,分析了干旱条件下外源脱落酸在诱导基因表达、调节植物激素水平、调控渗透调节物质含量及提高保护酶活性等生理生化过程中的重要作用。以外源脱落酸调节作物干旱为出发点,讨论了脱落酸在植物抗旱领域的研究现状和发展趋势,对植物节水抗旱增产具有重要意义,也为今后农业生产抗旱研究提供理论依据。
Drought stress can significantly affect plant photosynthesis,metabolism,osmotic regulation and other related physiological processes,and then affect plant economic traits.Exogenous ABA can alleviate the effect of drought on plant growth.We selected the exogenous ABA as the main discuss basis,this paper expounds the exogenous ABA increase crop physiological mechanism of drought resistance.The regulation of photosynthetic physiological by exogenous ABA in drought stress was introduced,and the induction of gene expression,the regulating the osmotic regulation substances content and the activity of protective enzyme and the important role of physiological and biochemical process.Taking exogenous ABA as the starting point to regulate crop drought,this study discussed the current situation and trend of ABA research in the field of plant drought resistance,which is of great significance for water-saving,drought resistance and yield increase of plants,and also provides theoretical basis for future studies on agricultural production drought resistance.
