Green house experiment was conducted to investigate the effect of growth regulator on physiological and biochemical changes in mothbean irrigated with saline water. The experimental design was factorial completely randomized design with two level of irrigation to induce salinity stress i.e. tap water (S1) and 4 EC saline water (S2) and different eight (T1 to T8) treatment combinations. The plants were sprayed with indol acetic acid, gibberellic acid, salicylic acid and their combination treatment after 15 and 25 DAS (Days after sowing) and samples was drawn after 20 and 30 DAS for the analysis. The observations were recorded for the parameters viz., relative water content, membrane stability index, leaf pH, total soluble sugar, reducing sugar, proline, glycine betaine, ascorbic acid. The results suggest that the collected samples of the mothbean that was irrigated with salt stress it shown decreased in the physiological parameters viz.; relative water content, membrane stability index but leaf pH showed reverse trend and it was increased in case of high salt concentration. The decreased in relative water contents in present experiment was low may be the effect of accumulation of osmolytes viz.; reducing sugar, total soluble sugar, proline and glycine betaine. Higher concentration of salt that increase total soluble sugar, reducing sugar, proline, glycine betaine and ascorbic acid content with increasing salt concentration. The leaf sample treated with growth regulators and their combination at different concentration that was increased physiological parameters viz.; relative water content, membrane stability index, escape leaf pH also regulate various plant metabolic process and modulate the production of varied osmolytes viz.; total soluble sugar, reducing sugar, proline, glycine betaine and ascorbic acid content This investigation has proved growth regulators (Indol acetic acid, Gibberellic acid, Salicylic acid) and their combination as a potential biomolecules in reducing the adverse effect of salt stress in plant. A growth regulator (Indol acetic acid, Gibberellic acid, Salicylic acid) has been showed to be beneficial for plant in growth and development under salinity stress.
