Growth hormones are naturally occurring or synthetic compounds that regulate plant growth and development. The most common plant growth hormones include auxins, gibberellins, cytokinins, ethylene, and abscisic acid. These hormones control processes such as cell elongation, root formation, flowering, fruit development, and dormancy. Growth hormones are often used in agriculture and horticulture to promote rooting in cuttings, control plant shape, and improve crop yields.
