Question

List out two sets of plant growth regulators having antagonistic action.​

Answer 1

The two sets of plant growth regulators having antagonistic action are as follows:

• Gibberellic acid (GA) and abscisic acid (ABA) are two phytohormones that are generally recognised as key endogenous regulators that play antagonistic roles in plant developmental processes and environmental reactions.
• Abscisic acid (ABA) and gibberellins (GA) work in opposition to each other to regulate a variety of plant developmental processes, including seed maturation and seed dormancy and germination, primary root growth, and flowering timing.
