Solution
Plant growth promoters:
Plant growth promoters are plant hormones that lead to the development and growth of plants.
Three prominent plant growth promoters are Auxins, Gibberellins, and Cytokinins.
Auxins induce cell differentiation, cell division, and elongation.
Gibberellins induce seed germination, cell division, elongation, and root growth.
Cytokinins promote shoot initiation and growth, leaf senescence, and apical dominance.
