Cytokinin promotes
WebCytokinin generally induces the shoot proliferation and produces flower buds, and possesses the property of apical dominance, with auxiliary bud growth. They also promote leaf senescence, whereas auxins produce a root system. In general, cytokinins are of three types such as kinetin, zeatin, and 6 benzyl amino purine (BAP).

Cytokinins (CK) are a class of plant hormones that promote cell division, or cytokinesis, in plant roots and shoots. They are involved primarily in cell growth and differentiation, but also affect apical dominance, axillary bud growth, and leaf senescence.
