Plant dry weight, leaf CO2 assimilation, and root respiration were reduced significantly under moderate saline stress (40mM NaCl) but application of either urea or MeJA maintained growth, gas exchange parameters, and leaf N-NO3 − concentrations at values similar to those of non-salinized plants. Additionally, when these two foliar treatments were applied leaf Na+ concentration was reduced compared with control plants grown at 40mM NaCl. However, at a higher salt concentration (120mM NaCl), no effect of the foliar applications was found on these parameters. Salinity also decreased leaf δ15N but increased δ13C. Our study shows the feasibility of using foliar urea or MeJA to improve tolerance under moderate saline stress.
