Abscisic acid (ABA) is an inhibitory hormone in plants that helps a plant adapt to stress. It also plays a key role in the closure of the plant’s stomata, bud development, and seed dormancy. The hormone not only allows the plant to survive during times of adversity, but also assists the plant in adapting to the changing seasons.
Abscisic acid was first discovered in the cotton plant during the early 1960s by F.T. Addicott and his associates. It occurs in a plant’s leaves, green fruits, stems, and in the roots.
