The tolerance of two durum wheat varieties was tested under different levels of salinity using an experimental approach in the laboratory. The results show that the Vitron variety performs significantly better than the Simeto variety despite the fact that the tolerance threshold of both varieties to NaCl is lower than 2 gr/ l. The germination capacity of the Simeto variety was significantly lower than that of the Vitron variety which germinated in a relatively average time of 4 days and recorded the highest germination rates, 73% for seeds watered with distilled water, 53% at 2g/l , and 33% at 5g/l  of NaCl , a significant decrease in coleoptile and root length was recorded for both varieties, the Simeto variety recorded significantly higher levels of proline than the Vitron variety, 0.346 µg/ml vs 0.280 µg/ml under 2 g/l , respectively.
