摘要:

近年来全球气候变化异常,极端天气和农业气象灾害频发,突发性低温胁迫已经成为农业生产中最常见的非生物胁迫之一。低温胁迫影响植物生长发育,对植物的生理机能、细胞膜组分及结构可产生直接或间接影响,降低作物产量和品质,严重制约农业生产。合理施用外源脱落酸(ABA)能够缓解低温胁迫对植物理化进程的影响。本综述系统阐述了低温胁迫对植物理化过程的影响,分别从光合生理、逆境生理、细胞膜组分及细胞结构、激素水平及基因表达等方面阐明了植物对低温胁迫的应激反应,分析了外源ABA缓解低温胁迫的积极效应。本课题论述了外源ABA缓解低温胁迫的研究现状和发展趋势,对农业稳产保产具有重要意义,也为今后植物抗冷研究提供理论依据。

Abstract:

Global climate change is producing abnormal, extreme weather and agricultural meteorological disasters linked to climate change now occur frequently. Sudden low temperature stress has become one of the most common abiotic stresses in agricultural production, and low temperature stress more generally has become one of the most common abiotic stresses in agricultural production in recent years. Low temperature stress interferes with plant growth and development, and can directly or indirectly affect physiological functions, cell membrane components and structure of the plant, thus reducing yield and quality, and seriously restricting agricultural production. Application of exogenous ABA at appropriate rates can alleviate the effects of low temperature stress on physicochemical processes. Here we systematically expound the effects of low temperature stress on the physicochemical processes of plants and clarify the mechanisms of plant responses to low temperature stress, including aspects of photosynthetic physiology, stress physiology, cell membrane components and cell structure, hormone levels, and gene expression. Furthermore, the positive effects of exogenous ABA in alleviating low temperature stress are analyzed. This paper discusses the research status and development trends with respect to the use of plant growth regulators for alleviation of low temperature stress. This topic is of great significance for stable production and preservation of agriculture, and also provides a theoretical basis for future research on plant cold resistance.
