Plant hormone

Plant hormones (or plant growth regulators, or PGRs) are internally-secreted chemicals in plants that are used for regulating the plants growth. According to a standard definition, plant hormones are signal molecules produced at specific locations, occur in low concentrations, and cause altered processes in target cells at other locations.

It is accepted that there are five major classes of plant hormones:

auxins cytokinins(CK’s) ethylene gibberellins (GA’s) abscisic acid (ABA)
