Abstract—The aim of our work is to study the response of the barley plant (Hordeum vulgare L.) to salt stress, at different NaCl concentrations (0, 50, 100, 150 and 250 mM) and follow its growth over time in the effect of salt stress . The control is based mainly on measurements of biometric parameters: length of the aerial and underground parts, fresh biomass, dry biomass and leaf area. The results clearly show the influence of salt stress on these parameters. The variety of barley, studied, showed good resistance to the phenomenon at concentrations not exceeding 150 mM salt. The study of the variance of the different parameters with ANOVA revealed no significant differences in the length of the ground aerial part and fresh biomass variations, the latter is very highly significant at a concentration greater than 150 mM of salt. Dry biomass showed no significance for concentrations less than 150 mM, while it is very highly significant for 250 mM NaCl. With regard to the leaf surface, the variations are significant for less than 100 mM and very highly significant beyond 250 mM of salt.
