Background and Objective: There is an urgent need to pre-soaking in hormonal substance (GA3) and choosing the most tolerance cultivars to minimize the decreases of wheat germination characters and seedling parameters due to the high levels of salinity in either soil or water irrigation. Therefore, this experiment aimed to study the performance of some wheat cultivars under seed soaking in GA3, salinity stress levels and their interaction. Materials and Methods: A laboratory experiment was applied at Research Institute of Nyiregyhaza using Factorial Experimental based on Randomized Complete Block Design (RCBD) with four replications. Factors under study were six of wheat cultivars containing three Algerian cultivars i.e., Semito, Geta and Cirta and three Hungarian wheat cultivars i.e., Mikebudai, Komlo and Elet in relations of seed germination characters and seedling growth parameters were tested under seed soaking in gibberellic acid (GA3) at two levels of GA3 0 and 150 ppm and at six salinity stress levels 0, 3.5, 7.0, 10.5, 14.0 and 17.5 dS m–1. Results: Seed soaking before sown at 150 ppm of GA3 significantly affected germination characters and seedling properties and produced the highest values of germination characters as compared with non-soaking. Mikebudai cultivar exceeded all studied cultivars in all studied traits and recorded the highest values of tolerance index (TI) and the lowest values of seedling height reduction (SHR). Increasing salinity levels from 0, 3.5, 7, 10.5, 14 and 17.5 dS m–1 significantly affected all studied characters. Conclusion: Mikebudai, Cirta and Komoli cultivars clearly showed best cultivars with under seed soaking at 150 ppm of GA3 and the highest levels of salinity stress as compared with other six wheat cultivars under study.
