Abstract :This study was carried out in laboratory conditions of Ordu University to determinate responses of oil-sunflower germination to different salt stress and GA3 at germination time in University of Ordu. The laboratuary experiment was set up completely randomized design with 3 replications in 2016. In the study, four NaCl doses insert ignore into journalissuearticles values(0, 25, 50 and 100 mM); and five GA3 doses insert ignore into journalissuearticles values(0, 50, 100, 150 and 200 ppm); were used to sunflower plumula length, radicula lenght, germination time and percentage of germination. At this study; plumule length of sunflower seeds at different NaCl and GA3 ranged between 3.31-5.70 cm and 3.33-5.63 cm respectively. By increasing NaCl concentration, seed germination delayed and decreased. Radicula lenght of sunflower seeds at different NaCl ranged between 2.29-5.54 cm. In the study, a significant effect on the properties of sunflower seeds to germinate is unprecedented dose of NaCl and GA3.
