This study aimed to investigate the seed priming effects on the quality of tomato seeds under salinity and nonsalinity conditions. The factorial design was carried out in the form of completely randomized design (CRD) with four replications. The treatments included priming (Control, tryptophan, proline and arginine with five mM concentration) and levels of salinity (0, 30, 60mM NaCl). As salinity increased, means of germination percentage, germination rate, length of radicle, plumule and seedling, and seedling dry weight decreased. Seed priming with proline compensated radicle length reductions caused by salinity. Seed priming had an improving effect on seedling dry weight and increased germination percentage, germination rate and length of radicle. Prolineprimed seeds improved seed quality better than tryptophan and arginine-primed seeds.
