Abstract :Objective: Global climate change has negative effects on plants. Also, abiotic stresses, especially water stress, have negative effects on plants. The aim of the study is to determine the responses of different tomato varieties in terms of plant development at young plant stage and different water levels. Materials and Methods: The study was carried out in the climate chamber of the Department of Horticulture, Sirnak University. F1-Seminis and SVTD 8008 F1-Hazera 5656 and tomato variety were used as materials and vermiculite as substrate and Hoogland nutrient solution for irrigation. The experiment was conducted under five irrigation levels: 15%, 25%, 50%, 75%, and 100% (control).. Evaluation with 0-4 (score) Scale in green shoot , leaf number, plant height, plant stem, fresh and dry weights, leaf area, leaf relative water content (RWC), chlorophyll density (SPAD) in leaves, mineral elements (K, Ca), chlorophyll and carotenoid concentrations, total phenolic and total flavonoids were made. The trial was conducted according to the randomized plot design. Results: According to the measurement results in the experiment, Plant Height, Plant Stem, Fresh and Dry Weights, Leaf Area, Leaf Relative Water Content, Mineral Element (K, Ca), Total Phenolic and Total Flavonoids were found to be statistically significant. Conclusion: In water stress conditions, significant problems are experienced in plant production. Significant decreases are known, especially in plant growth and cell division. As a natural result of this, there are decreases in the number of leaves, plant height, leaf area, stem diameter, leaf relative water content and dry matter content rates. In the study, it was determined that the F1-Hazera 5656 variety, which was subjected to water stress, was more tolerant to water stress than the F1-Seminis 8008 variety.
