The video explains plant growth regulators, including auxins, cytokinins, gibberellins, ethylene, and abscisic acid. Auxins promote cell growth and apical dominance, while cytokinins aid in cell division and delay leaf senescence. Gibberellins enhance stem elongation and seed germination. Ethylene, a gaseous hormone, influences fruit ripening and leaf senescence. Abscisic acid acts as a growth inhibitor, inducing dormancy and reducing transpiration.
