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.
