Germination of pelleted seeds of different lettuce cultivars was evaluated. The experimental design used was completely randomized, with four replications, in a factorial outline 5 x 4. Seeds of 'Elisa', 'Veronica AF 259', 'Vera' and 'Tainá' were tested. The sodium chloride (NaCl) concentrations used were 0; 50 Mm(2,9222 g/L); 100 Mm (5,8443 g/L); 150 Mm (8,7665 g/L); and 200 Mm (11,6886 g/L). Germination percentage, germination rate and number of normal seedling were evaluated. The concentration of 200 Mm of NaCl resulted in the lowest number of germinated plants. 'Veronica AF 259' germinated in the shortest time using a concentration of 150 Mn of NaCl.
