Read the following statements regarding Plant Growth Regulators (PGRs): (A) Gibberellins promote bolting in beet, cabbages and many plants with a rosette habit. (B) Ethylene delays the senescence and abscission of leaves and flowers. (C) Cytokinins help in overcoming apical dominance. (D) Abscisic acid acts as an antagonist to GAs in most situations. (E) 2,4-D is widely used to kill mature monocotyledonous weeds. Sel

Step-by-step solution

Statement (A) is correct as gibberellins promote bolting (internode elongation just prior to flowering) in beet, cabbages, and many plants with a rosette habit. Statement (B) is incorrect because ethylene promotes senescence and abscission of plant organs, especially leaves and flowers. Statement (C) is correct as cytokinins promote lateral shoot growth and help overcome apical dominance. Statement (D) is correct because abscisic acid (ABA) generally acts as an antagonist to gibberellins (GAs), for example, in seed
