Cytokinins are plant growth promoters that promote cytokiness or cell division, promote nutrient mobilisation and control apical dominance.
Apical dominance is a phenomenon in which the growth of the maincentral stem of the plant is more as compared to the others.
Auxin inhibits the growth of axillary buds and restricts lateral branching. However, cytokinin acts antagonist to auxin in this regard and promotes lateral shoot growth which makes the plant bushy.
