Question

What are the effects of cytokinins on plant growth?

Answer 1

The physiological effects of cytokinin which are observed on the growth of plants are as follows:

(1) Cytokinin results in the promotion of cell division.

(2) Along with auxin, cytokinin initiates bud and root formation in the callus tissue in plant tissue culture.

(3) Cytokinin promotes the growth of lateral buds when added in the medium even if the apical bud is intact.

(4) Cytokinin breaks the dormancy of seeds and promotes germination.

(5) Application of cytokinin delays the process of ageing in plants.
