WebCytokinin is a plant hormone. It promotes cell division. It also delays the destruction of chlorophyll and protein. It shows delay of senescence in leaves. It is mostly produced in the root apex. When an excised leaf is induced to root, it does not turn yellow because root apex synthesizes cytokinin hormone. WebCytokinins can stimulate the synthesis of nitrate reductase in dark-grown leaves, which suggests that the light requirement for the induction of this enzyme can be partly substituted by cytokinins. It has been further observed that along with the induction of nitrate reductase by cytokinin, there is a corresponding increase in nitrate reductase ...
