Application
As a crucial phytohormone, abscisic acid participates in regulating numerous physiological activities during the entire growth cycle of plants. It promotes defoliation, suppresses plant growth, and induces dormancy. Moreover, it stimulates stomatal closure, affects the development of seed embryos, and enhances plant tolerance to adverse environments such as drought, low temperature and salt stress. This multifunctional hormone is widely applied in agricultural production, ecological restoration and other related fields.
