Which of these is not a growth promoter? (RJ AA0 2012)

✅Explanation: Abscisic acid is a plant hormone that acts as a growth inhibitor. It plays a role in processes like dormancy and stress response.

📌 Other Options Explanations:

✏️Auxins:
-Promote cell elongation and growth.
-Involved in apical dominance and root formation.
-Stimulate fruit development and inhibit abscission (dropping off).

✏️Gibberellins:
-Promote stem elongation and seed germination.
-Break dormancy in seeds and buds.
-Stimulate flowering and fruit development.

✏️Cytokinins:
-Promote cell division and shoot development.
-Delay leaf senescence (aging).
-Involved in nutrient mobilization and tissue growth.

• Other Important Plant Hormones:

✏️Ethylene:
-Regulates fruit ripening and flower wilting.
-Promotes leaf abscission and senescence.
-Involved in responses to stress and pathogen resistance.

✏️Abscisic Acid (ABA):
-Induces stomatal closure during water stress.
-Promotes seed dormancy and inhibits germination.
-Involved in stress responses and regulation of growth.
