History of Abscisic Acid (ABA) In 1963, abscisic acid was first identified and characterized by Frederick Addicott and his associates. They were studying pounds responsible for the abscission of fruits (cotton). Two pounds were isolated and called abscisin I and abscisin II. Abscisin II is presently called abscisic acid (ABA)(Addicot, 1963). Two other groups at about the same time discovered the same pound. One group headed by Philip Wareing was studying bud dormancy in woody plants. The other group led by Van Steveninck was studying abscission of flowers and fruits from lupine. Plant physiologists agreed to call the pound abscisic acid (Salisbury and Ross, 1992).
