The growth and development of plants are inhibited by abiotic stress, which is one of the factors limiting crop yield increase. Abscisic acid (ABA) is an important plant hormone and plays a key role in plants' response to abiotic stress. This study summarized the role of abscisic acid in abiotic stress of plants, introduced abscisic acid from its discovery, distribution and transportation, discussed the role of abscisic acid in abiotic stress from three aspects: drought stress, salt stress and high temperature stress, and prospected the application prospect of abscisic acid in agriculture, in order to lay a foundation for further research on abiotic stress of plants and provide theoretical reference for workers engaged in agricultural production and related research.
