Abscisic acid, a plant hormone, plays a key role in regulating various physiological processes throughout the plant's development. It aids in leaf shedding, inhibits growth, and promotes dormancy. Additionally, it triggers stomatal closure, influences seed embryo development, and boosts the plant’s ability to withstand harsh conditions like drought, low temperatures, and salinity. This versatile hormone finds extensive use in agriculture, ecological vegetation projects, and other related areas.
