Abstract:
Plant growth regulators are artificially produced substances in very low quantities normally. They play an important role in earliness, sex modification, increasing the yield, quality, resistant to insect-disease, regulate the growth of plants and are important measures to ensure production. It decreased susceptibility towards biotic and abiotic stress, improved morphological structure, facilitation of harvesting, and modification of plant constituents. The main plant growth regulators are Auxin, Gibberellin, Cytokinin, Jasmonic acid, ethylene, abscisic acid (ABA) and brassinosteroids etc. They have multiple functions and various combinations of them can act either synergistically (auxins and gibberellins) or antagonistically (abscisic acid and auxins) to promote very specific responses.
