Tomato seeds of cv. Quadrado Mix, Calmec VFN and Topmec were classified by sieves of 3.5mm and 4.7mm diameter and submitted to osmotic conditioning. The experimental design was the completely randomized as a factorial 2x6 (osmotic conditioning x lot), for storage period, with four repetitions. The seeds were immersed in solutions supplied with air at 20ºC in PEG 6000 solutions at 0.0 and -1.0 MPa, during seven days. The results led to the conclusion that immediately after the treatment and up to 30 storage days, the conditioned seeds showed larger germination and vigor, independent of cultivar and diameter. However, after 120 storage days, the conditioned seeds of cv. Quadrado Mix showed larger germination and vigor than non-conditioned seeds.
