Which hormone is considered a growth-inhibiting hormone in plants?
Answer and explanation
Correct answer: Abscisic acid
Abscisic acid, commonly abbreviated as ABA, is generally described at this level as a growth-inhibiting plant hormone. It promotes dormancy and helps plants respond to stress, such as water shortage, partly by causing stomatal closure. Auxin, gibberellin, and cytokinin are chiefly associated with growth promotion and development, although hormones can have context-dependent effects. Therefore, option A is correct.
