In this study, the difference between the resistance of wheat plants (c3) and maize (c4) the salinity was investigated. Research on environmental stresses (Hakimi, 2008) show thatstresses are considered as Limiting factors in crop production.and some phenolic compounds such as salicylic acid are used to improve or alleviate the negative effects of stress. In this study, plants were grown in plastic pots and the plants treated with salicylic acid, after two weeks and seven days later salinity was exerted.The effect of salinity treatmenton both plants, for some morphological and biochemical characteristics were studied. In biochemical tests, lipid peroxidation under salinity and salicylic acid treatments has increased for weat which represents the effect of salinity on the plant and the activetion of the defense mechanism, Howweverthese factors have reduced formaize. Moreover, the increase in total chlorophyll and flavonoids in wheatchlorophyll in wheat and maize shows the role of these pigments in quenching hydrogen peroxide and other active Oxygen types. This increases has not been concideralle in maize. The effect of treatment on the weight of … and root of both plants differed under the investigated concentration.

Keywords: Biochemical parameters, Morphological, Salicylic acid, Salt.
