A factorial experiment was conducted in the seed technology laboratory, department agronomy of agriculture, Omar El Mokhtar University during season 2023 to study response of two Lentil varieties (Brisch and Shawish) to germination and seedling growth when treated using different concentrations of sodium chloride salt NaCL (control, 25 Mml,50Mml and 75Mml)in a randomized complete block design. The results indicated that the brish variety was superior to the shawish variety in average traits (germination percentage, shoot length, root length, shoot wet weight, root wet weight, shoot dry weight, germination rate (GR), germination index(GI), tolerance index (TI) and seedling vigour index (SVI). Increasing sodium chloride salt levels up to 100 mML led to a decrease in the germination rate and most of the studied traits, as the lowest values were recorded when treated with 100 Mml sodium chloride salt concentration of (2.280 cm ,0.767 cm, 0.0103 g, 0.522,0.931 and 0.273) for the characteristics of shoot length, root length, root wet weight, root dry weight, germination rate(GR), germination index(GI) and tolerance index (TI), respectively, compared to the control treatment.
