Detailed explanation-1: -(a) Auxins are group of plant hormones synthesized at the shot-tip of the plant. (b) Gibberellins stimulate stem elongation. (c) Cytokinins delay the ageing in leaves. (d) Abscisic acid is a growth inhibitor.
Detailed explanation-2: -They are also referred to as plant growth hormones or phytohormones. Auxin, cytokinin, gibberellins, and abscisic acid are some examples of plant growth regulators. Auxins are a group of naturally occurring and artificially synthesised plant hormones. They play an important role in the regulation of plant growth.
Detailed explanation-3: -The five major phytohormones are – auxins, gibberellins, cytokinins, ethylene and abscisic acid.
Detailed explanation-4: -There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA).
