The commercial applications of cytokinins are:
-
Auxins and cytokinins together encourage cell division.
-
Cytokinins induce bud and root formation in callus.
-
It has important role in morphogenesis so very useful in tissue culture.
-
Cytokinins promote the growth of lateral buds but the presence of auxins in the shoot apex results in apical dominance. Apical buds are removed in tea plantation to obtain short branched tea plants.
-
It retards the senescence of plant parts.
