Abscisic acid - Flowering hormone

Vedclass · Answer

(D) Abscisic acid $(ABA)$ is a naturally occurring plant growth inhibitor. It is known as a 'stress hormone' because it helps plants cope with adverse environmental conditions. It promotes the abscission of leaves, fruits, and flowers, and accelerates senescence. It does not act as a general flowering hormone; in fact, it often inhibits growth and development. Therefore, the pair 'Abscisic acid - Flowering hormone' is incorrect.
