To study on effect of polyethylene glycol (PEG) and NaCl stress on germination and early seedling stages on two genotypes of wheat, two separated experiment were laid out at laboratory, in Iran in 2010. This investigation was performed as factorial experiment under Complete Randomized Design (CRD) with three replications. Cultivar factor contains of two genotypes (Seimareh and Leucurum) and five levels of stress (0, -2, -4, -6 and -8 bar). Results indicated that significant decrease in percentage of germination, germination rate, length of radicle and plumule and radicle and plumule dry matter. On the basis of the results, NaCl as compared with PEG had more effect on germination and early seedling stage and Seimareh had more resistant than Leucurum in both stress conditions.
