Aims: To study the effect of salinization levels on four cultivars of wheat plant, Gimiza 11, Sakha 94, Gimiza10 and Giza 186 the effect of salinization levels on the germination percentage, growth parameters at seedling stage (length, fresh and dry matter and water content of shoot and root. Study design: Experimenal. Place and Duration of study: Minia University, Faculty of Science, Botany and Microbiology Department, El- Minia University. between September, 2013 to January 2014. Methodology: Grains of each cultivar were germinated under different osmotic stress levels 0.0, 50mM, 100mM, 150mM, 200mM, 250mM and300mM NaCl levels. Results: The result indicated that Skha94 was the most sensitive, the most tolerant was Giza168 and the Gimiza 11 following Gimiza 10 were the intermediate cultivars. Conclusion: It can be concluded that the tolerance strategy was different according to speies and the stages of grains development.
