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. There are two types of cytokinins: adenine-type cytokinins represented by kinetin WebCytokinins which promote cell division and cell differentiation of plants are structurally classified into two groups: purine-type cytokinins and phenylurea-type cytokinins.
