WebSep 9, 2024 · Cytokinins are known to alleviate the damage engendered by different abiotic stresses ( Bryksová et al., 2024) and it also has wide application in plant tissue culture due to its stimulatory impact over the regeneration of plants ( Grzegorczyk-Karolak et al., 2024 ). WebThus cytokinin has been documented as a permissive agent in germination by antagonizing the inhibitor action — a case of cytokinin-inhibitor antagonism. In bud growth also, inhibitor (preventive) and cytokinin (permissive) show opposite effects. Thus inhibitor-induced bud dormancy can be overcome by cytokinin. (vii) Apical Dominance:
