Özet: Along with global warming, serious reductions occurred in water resources. The drought stress resulting from global warming has greatly affected production. As well as reducing yield and quality in production, drought also reduces farmer's income. One of the measures to be taken in order to minimize the damage caused by the effect of drought stress is to determine the tolerance of the genotypes to drought. Accordingly, three hybrids varieties, three standards varieties and three landraces of tomatoes were used in the present study. Tomato seeds were sown in a 2 liters-pot that contains 1:1 mixture of peat + perlite. After the true leaves emerged, the seedlings were irrigated with the Hoagland nutrient solution. While irrigation was carried on the control plants until the end of the application, irrigation was completely terminated during the seedling period in the plants that are exposed to drought. 12 days after the irrigation cut in tomato genotypes, the changes in the level of catalase (CAT), superoxide dismutase (SOD), ascorbate peroxidase (APX), potassium (K), calcium (Ca) and magnesium were examined. It was observed that there were significant differences in these parameters examined for the determination of tomato genotypes that are tolerant and sensitive to drought stress.
