The results of this study showed that different levels of osmotic stress significantly affected the germination percentage, germination rate, germination index and coefficient of velocity of germination. The highest germination was observed at cultivar F135ST, even at the highest PEG concentrations, meanwhile Sugargraze II was the most affected by the increase of osmotic stress. Considering the germination rate, the highest mean values at V0 were registered at Sugargraze II and F13ST cultivars, but in the same time Sugargraze II was seriously affected by the increase of PEG concentration. The highest germination speed at V2 was at F135ST cultivar. Germination index presents very high variability amongst the cultivars and PEG concentrations. Thus F135ST cultivar has an average germination index at Vo variant above 600, and at V2 variant, the values decrease below 500. The Sugargraze I cultivar has slightly lower values of germination index than F135ST, but the mean values vary similarly. Instead, at Sugargraze II we could observe a more drastic decrease of germination index, from 575,33 at V0 variant, to 244 at the highest PEG concentration of V2. Very similar to this index is the variation of coefficient velocity of germination
