Abstract
Salinity is a major constraint for mungbean seedlings establishment. Salicylic acid (SA) is an endogenously synthesized signaling compound contributes to regulate physiological processes in plants as well as biotic and abiotic stress responses. Effect of SA seed priming of mungbean in developing resistance under salt stress was investigated. The seeds of mungbean varieties (NM-2016 and NM-20-21) were soaked in 0.01% and 0.02% of SA while, no priming and hydropriming was taken as control. Seeds were sown in washed river sand with two salinity (0, 80 mM NaCl) levels. The results showed that priming with 0.01% SA improved plant height and dry biomass as compared with hydropriming and non-priming plants under salt stress. Meanwhile, 80 mM salt stress notably decreased the concentrations of Ca2+, N, P, and K+ while Na+ and Cl- contents increased in leaves as compared to control plants. But 0.01% SA improved the concentrations of almost all nutrients except Mg2+ under salt stress as compared to hydropriming and control. Collectively, NM-20-21 variety performed better than that of NM-2016 and seed priming with 0.01 % SA was found more effective in improving growth and nutrient uptake of mungbean seedlings
