摘要：This study was carried out in order to test the effect of different salinities co ncentrations on germination and several physiological traits in three Moroccan barleys cultivars including Arig 8, Asni and Tamelalt. Five different salinities concentrations were used (5, 10, 15 and 20 g/L) in the watering against a control (0g/L). The cultivars showed statistically significant (P<0.001) responses to salt stress. The increase of NaCl concentrations reduced significantly every measured traits, as the final germinating percent, roots and shoots lengths, fresh and dry bio mass, relative water content and salt tolerance index, in all the cultivars. The salt tolerance index can be used as an effective criterion to choose tolerant genotypes. Based on this index, these studies led us to conclude Asni (with 42.75%) and Arig 8 (with 47.66%) to be salt-sensitive and moderate salt-sensitive cultivars, respectively, and Tamelalt (with 59.77%) to be a salt-tolerant cultivar; this assertion allowing the last one to be cultivated in saline soil
