Cytokinin - Wikipedia
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.
Cytokinin | Definition, Functions, & Uses | Britannica
Cytokinin, any of a number of plant hormones that influence growth and the stimulation of cell division. Cytokinins are synthesized in the roots and travel through the xylem to the leaves and fruits, where they are required for normal growth and cell differentiation.

As one of the classic groups of phytohormones, CKs have long been known for their potent promotion of plant growth. In fact, the original definition of a CK was for a compound which promoted cell division [].Over the decades since their early discovery in coconut milk, herring sperm and corn kernels, the cytokinins have gained a reputation for being involved in almost …
Cytokinin - an overview | ScienceDirect Topics
Cytokinins are compounds with a structure close to adenine. They are usually linked to an isopentenyl side chain. Kinetin was the first artificial cytokinin to be discovered. It was isolated from herring sperm and named after its ability to promote cell division.
