Natural and anthropogenic salinization through intense and progressive periods of drought, as well as due to the use of fertilizers or the soil parental material, leads to degradation of soil quality. In this context, wheat, one of the most important crops, is threatened. Specific objectives include measuring chlorophyll content and morphological parameters such as grain number, fresh and dry biomass for stems and spikes. The experiment was set up in field conditions, in mesocosms, under six saline doses of 15-30-45-60-75 mM NaCl and a control without salt, in five replicates. The results highlighted different effects depending on the tested variety and the applied salinity doses. The most concentrated dose of 75 mM NaCl drastically reduced the values of almost all morpho-physiological parameters in all varieties. Transilvania, Arieșan, Faur, Ciprian, Pădureni, and Bezostaia had higher morpho-physiological parameter values. Otilia is the wheat variety most sensitive to salinity stress. Different tolerance patterns and trends were observed based on the interaction between the variety and salinity dose.
