Cytokinins Hormone
In the process of cytokinesis, cytokinins are important. Plants that experience fast cell division, such as those with root apices, shoot buds, early fruits, etc., naturally produce cytokinins. Cytokinins migrate in a polar and basipetal manner.
Natural: Isopentenyl adenine, zeatin (corn kernels, coconut milk).
Synthetic: thidiazuron, kinetin, benzyladenine, and diphenylurea.
Functions of Cytokinins hormone:
(i) It is used to start shoot growth in culture and promotes lateral and adventitious shoot growth.
(ii) helps in combating auxin-induced apical dominance.
(iii) promote the growth of leaves’ chloroplasts
(iv) promotes the mobilisation of nutrients and delays leaf senescence.
