Plant growth is stimulated by the presence of auxins, ethylene, and abscisic acid.

Plant growth regulators are the plant hormones that are responsible for plant growth, Auxins are the weak acidic hormones that promote cell elongation and growth. Ethylene is the gaseous hormone that stimulates transverse growth but inhibits longitudinal growth. Abscisic acid is the stress hormone that inhibits growth and promotes bud dormancy.
