Salinity is the most detrimental stress which impairs growth and development of plants. Seven days old seedlings two contrast genotypes maize (Zea mays L.), tolerant (9120 Super Gold) susceptible (Pacific 984 PS999), were subjected to 12 dSm-1 salinity for five contents chlorophyll (Chl), carotenoid (Car), methylglyoxal (MG) as well activities glyoxalase I (Gly I) II II) investigated in fully expanded leaves. Loss Chl Car higher compared those genotypes. Production MG was also genotypes, Pacific PS999, that ones under stress. Under salinity, showed 105 91% over 9120 Gold, respectively, while PS999 75 63% respectively. On other hand, both Gly played important role reducing cytotoxic
