It was aimed to determine the effects of gamma rays (25, 50 and 100 Gy) in Gina and Romano cultivars under restricted irrigation conditions. Control (100%) and 50% water deficit were subjected to the seedlings grown in the climate room conditions at 23±2 °C temperature and 16:8 light:dark period. At the end of the study, seedling growth parameters such as shoot length and diameter, number of leaves, shoot and root fresh-dry weights, root-shoot ratio of were measured. Also leaf rational water content (LRWC), photosynthetic pigment content, lipid peroxidation (Malondialdehyde (MDA)), membrane damage and index, and nutrient content in shoot were examined. Gamma irradiation applications increased approximately 49% in shoot length in Gina cultivar, and increased by 13% and 6.5%, respectively, in 25 and 50 Gy stress conditions compared to non-irradiated plants. It was observed that root length decreased in water deficit with increasing radiation dose, especially in Romano cultivar, but increased by 88% in Gina variety. It was found that lipid peroxidation decreased by 7.7-32.5% in both cultivars. It was determined that 100 Gy radiation doses were more prominent in morphological features and 50 Gy in physiological features and nutrient intake.and 50 Gy gamma rays were found to be more effective in both Gina and Romano cultivars.
