Abstract
This research was carried out to determine effects of gibberellic acid (GA) (25, 50 and 100 ppm), kinetin (K) (10, 25 and 50 ppm), ascorbic acid (AA) (0.50, 0.75 and 1.00 mM) and hydropriming on germination of eggplant under salt stress (0 mM, 60 mM and 120 mM NaCl) in Atatürk University, Faculty of Agriculture, Department of Horticulture. Seeds were kept in distilled water, GA, K and AA solutions for 24 h. Then, 50 seeds were put petri dishes with 0 mM, 60 mM and 120 mM NaCl. In the study, it was determined that salt stress negatively affected germination percentage (GP) and mean germination time (MGT) in eggplant. However, it was found that hormone and water treatments significantly improved GP and MGT compared to control and ameliorated the negative effect of salt stress. The best practice for GP and MGT was hydropriming under salt stress. According to the results obtained from the study, hydropriming and hormone treatments can be used as an alternative method in reducing the negative effects of salt stress in eggplant during germination.
