WebStatement I : Cytokinin is a hormone that promotes cell division and delays the onset of senescence. Statement II : Cytokinin is a term used for cell division. Statement III : Cytokinin helps in breaking seed dormancy. Statement IV : Cytokinin promotes lateral bud growth and control apical dominance. A. WebCytokinins are plant-specific chemical messengers (hormones) that play a central role in the regulation of the plant cell cycle and numerous developmental processes. Cytokinins were discovered by F Skoog, C Miller, and co-workers during the 1950s as factors that promote cell division (cytokinesis).
