Salinity is one of the major environmental problems facing many countries in the agricultural sector, affecting the growth and productivity of agricultural crops such as wheat, which is one of the most important staple food crops, especially in Libya This study was conducted in the laboratory of the Department of Botany, Faculty of Arts and Sciences, Qaminis, Benghazi University. The aim of the study was to evaluate the effect of salinity on seed germination and early vegetative growth of two local wheat cultivars (Kassi and Buhuth 210) under four concentrations of sodium chloride (300, 200, 100, and 50 mM), in addition to distilled water (control). The results showed that increased salinity negatively affected most of the studied germination parameters and led to a decrease in germination capacity by (25.3 and 21.4%) for the Kassi and Buhuth 210 cultivars, respectively. The study revealed that increasing salinity concentration significantly reduced germination rates in the studied wheat varieties, decreasing the germination index (GI) by 29.3 and 42.3%, the germination rate index (GRI) by 31.1 and 25.41%, and the coefficient of germination velocity (CVG) by 46.1 and 32.1%. It also increased the mean germination time by 1.22 and 0.92 days for the Kassi and Buhuth 210 varieties, respectively, at a concentration of 300 mM. Furthermore, the study found that a gradual increase in salinity concentration affected the seedling growth characteristics of both varieties, reducing shoot and root length and decreasing fresh and dry weights. The results of the experiment also indicated that both varieties exhibited tolerance to high salinity, especially during the germination stage, indicating their suitability for cultivation. It is recommended that they be used in soils most affected by salinity.................. Keywords:...........Salinity, Wheat, Kassi, Buhuth210, Germination parameters. المقدمة
