The hormone cytokinin is found in regions of rapid cell division, like root and shoot tips, promoting growth. The hormone abscisic acid (ABA) inhibits growth and induces dormancy under stressful conditions.

In plants, cytokinin is present in areas of rapid cell division, such as the shoot apex, root tips, and young fruits. It promotes cell division, growth, and delay of aging in leaves. On the other hand, abscisic acid (ABA) acts as a growth-inhibiting hormone, responsible for inducing dormancy in seeds and buds. It also helps plants withstand stress conditions like drought by closing stomata to reduce water loss. Hence, cytokinin promotes growth, while abscisic acid restricts it.
