Hormones are a unique class of chemical compounds that regulate and coordinate plant growth, development, and responses to the environment.
A part of the plant produces hormones, which are then transported to all the areas that require them.
The five main categories of phytohormones are ethylene, auxins, gibberellins, cytokinins, and abscisic acid.
These phytohormones are either growth promoters or growth inhibitors, including auxins, gibberellins, cytokinins, and ethylene.
