Soil salinity is one of the important and determinant factors in land degradation and desertification. This study was undertaken to investigate salt tolerance in Salsola tomentosa under greenhouse conditions to choose a suitable species for saline conditions. The treatment solutions for salinity tests were different concentrations of NaCl (0, 100, 200, 300, 400, and 500 mM) with three replicates. Fresh and dry weights, relative water content, leaf water potential, proline, soluble sugar and chlorophyll contents were measured. Data analysis was performed by SPSS software and Statistical analysis was done using Duncan for mean comparison. According to the results, fresh and dry weight of organs, chlorophyll content and leaf water potential were decreased with increasing salinity level. However, leaf relative water content, proline and total soluble sugars were increased with increasing salinity levels. Finally, we have to mention that nature is unpredictable and it is not impossible to observe unexpected trends in specific conditions.
