WebMar 28, 2024 · Cytokinesis or cell division is the process of cell proliferation and differentiation. Apical dominance, axillary bud growth, senescence of flowers, etc. are functions of cytokinin. It plays an important role in primary plant growth as it affects the cell division rate in the plant. Benzyl-aminopurine and kinetin are examples of cytokinins. WebCytokinins are utilized in tissue culture to stimulate cell division, adventitious shoot formation, and embryogenesis [121].
