The type of cytokinin cytokinins (cytokinin plant mitogen, CTK) is to promote plant cell division hormone. First discovered and purified natural CTK reported in 1963 Letham immature corn seeds isolated zeatin (ZR), which is separated from the corn and Miller reported in 1961 but not completely purified cell division the same substance. Five plant hormone cytokinin is the youngest member of the plant mitogen sold since 1955, Miller, Skoog et al found from herring sperm DNA degradation in plant mitogen until now, but twenty years. Although kinetin --6- furan diaminopurine was first discovered active substances stimulate cell division mitogen, but so far it has not found naturally in plant cells. But it was discovered from a large number of exploration in many young plant organs, cytokinins stimulate cell division there is substance. 63 years Letham first extracted from sweet corn grain filling stage and crystallized active substance named zeatin (Zeatin).
