Abstract
Some wheat genotypes were evaluated to salt stress during the germination and early seedling growth. Salinity, in general decreased germination percentage and seedling growth characters representing by root and shoot lengths as well as their fresh and dry weight in most studied genotypes depending on the genotypes and the level of NaCl salinity . however, genotypes Gemmeiza 7 and Gemmeiza 10 x C.B.255 showed a stimulation response to NaCl salinity up to 6000 mg/l . The stimulating effect of salinity on the two mentioned genotypes was discussed.
On the other hand, total sugars and proline concentrations were significantly increased in the shoots of all genotypes grown under salt stress. Moreover, Na+ concentration was increased whereas, that of K+ decreased in the shoots.
The data concluded that, cv(s) Gemmeiza  7 and Gemmeiza 10x C.B.255 of wheat were more tolerant to salt stress up to 6000 mg NaCl/l and the former cv proved to be more tolerant as compared to all studied genotypes.
