     A plant hormone is commonly defined as an organic substance that is produced in one part of a plant and translocated to another part where, at very low concentrations, it stimulates a physiological response. Plant hormones may promote or inhibit growth depending on the specific hormone involved, the concentration, the time, and the plant part it is acting on. Plant hormones occur naturally. When they are synthesized chemically, they are known as plant growth regulators, or PGRs. Some PGRs mimic the natural plant hormones, and others act by blocking either the synthesis or the activity of plant hormones. 

Gibberellins

Gibberellins also promote growth. They are produced in very young leaves, developing seeds, fruit, and roots. Gibberellins cause cell elongation during shoot growth, and are involved in regulation of dormancy. Commercially, gibberellins have been used to improve fruit size, prevent fruit russeting, and induce lateral branching.
