Ration of cytokinin to auxin controls call differentiation. If there is more cytokinin than axuin, shoot buds develop. Relatively more auxin than cytokinins leads to the development of roots. Abscisic Acid (ABA) is known as natural plant growth inhibitor. Gibberellin stimulates stem elongation, leaf expansion, bolthing, flowering etc. Ethyene is a fruit ripening hormone.
