Read the following statements regarding the physiological effects of plant growth regulators: (A) Gibberellins speed up the malting process in the brewing industry. (B) Spraying juvenile conifers with gibberellic acids hastens the maturity period. (C) Gibberellins promote bolting in beet, cabbages and many plants with a rosette habit. (D) In most situations, abscisic acid acts as an antagonist to gibberellins. How ma

Step-by-step solution

Statement (A) is correct as GA3 is used to speed up the malting process in the brewing industry. Statement (B) is correct because spraying juvenile conifers with GAs hastens the maturity period, which leads to early seed production. Statement (C) is correct as gibberellins promote bolting (internode elongation just prior to flowering) in beet, cabbages and many plants with a rosette habit. Statement (D) is correct because in most situations, ABA acts as an antagonist to GAs (for example, in seed dormancy where ABA
