Phytohormones are chemical substances that induce physiological responses in plants in minute concentrations. Apart from the classical five phytohormones viz., auxins, gibberellins, cytokinins, ethylene and abscisic acid, there are other well-known phytohormones like brassinosteroids, methyl jasmonates, salicylic acid, strigolactones etc., that have a profound role during abiotic stress tolerance. Plants are prone to various abiotic stresses like heat, chilling, freezing, drought, flooding, oxidative, salt, allelochemicals, radiation, light, wind, heavy metals stresses etc. Among the various abiotic stresses in plants, salt stress is an important aspect that hinders growth, metabolism and final yields of plants. The roles of above mentioned phytohormones which can alleviate the salt stress are slowly unfolding. The present review deals with the role of the phytohormones on the alleviation of salt stress in plants.
