dc.description.abstractObjective: This study was conducted to determine the suitability of drought stress induced by PEG-6000 for rapid screening of tomato genetic resources against drought stress. Material and Methods: Two cultivars; M28 F1 and Alyans F1 known as tolerant and sensitive, respectively; were tested. In seed germination test, two different PEG concentrations (4% and 6%) were compared with the control. The seedling stage test was performed in water culture. In this experiment, (1) bare rooted seedlings of which rooting medium were removed and (2) seedlings with rooting medium were used. Drought dose was ?s= -1.0 MPa (full dose) and gradually increased (-0.25, -0.50, -0.75 and -1.0 MPa) every 48 hours from 7 days after planting. Results: In seed germination test, the decrease in vigour index under drought stress was lower in M28 variety. In water culture, stress symptoms appeared slowly if the seedlings with rooting medium were used. The decrease in plant growth characteristics, and chloropyll, carotenoid and relative water content and increase in proline content under stress were lower in M28 Conclusion: It was concluded that the seed germination test by 4% PEG-6000 and water culture in which the drought stress was created by PEG-6000 (?s= -1.0 MPa) can be used to screen tomato genetic matierials for drought stress tolerance. © 2022 Journal of Agriculture Faculty of Ege University.
