•Abscisic acid- This hormone restricts the growth of the plant. It is responsible for the wilting of leaves.

•Gibberellins- It promotes the growth of the stem of the plant.

•Cytokinin- This hormone promotes the cell division process. It is present in those areas where cell division takes place at a higher rate.
