Abscisic acid, a plant hormone, plays a key role in regulating various physiological processes during different stages of plant development. It facilitates leaf abscission, inhibits growth, and promotes dormancy. Additionally, it triggers stomatal closure, regulates seed embryo development, and boosts the plant's resistance to environmental stresses like drought, low temperatures, and salinity. It finds extensive applications in agriculture, ecological vegetation restoration, and other sectors.
