WebMar 30, 2006 · Cytokinins are implicated in a wide variety of plant growth and development processes including cell division, organ formation and regeneration, apical dominance, vascular development, nutrient mobility, and senescence ( Mok 1994 ). 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
