In the present study the two maize cultivars were selected to examine the effect of salinity and the effect of GA3 on the
salinity stressed seeds, the tests were conducted in different conditions with different concentrations. Germination percentage,
vigour index and seedling length, chlorophyll content, protein, total free amino acids, protease activity were investigated. GA3
treatment and combination of GA3 and NaCl increased the germination percentage, vigour index and seedling length in SNL
cultivar and in MYMH cultivar these parameters were reduced
