Abstract :In this study, the germination and early seedling growth, biochemical and antioxidant enzyme activities insert ignore into journalissuearticles values(CAT, SOD, POD, and APX); of one-year, broad-leaved Linas safflower belonging to the Compositeae family were investigated at different salt concentrations insert ignore into journalissuearticles values(0, 50, 100, 150 and 200 mM);. With increasing salt concentration, a 68.83% decrease in seedling length, 71% in stem length, 34% in germination rate, and 77% in fresh plant weight were determined. In addition, total phenolic content insert ignore into journalissuearticles values(267%);, total flavonoid content insert ignore into journalissuearticles values(904%);, CAT insert ignore into journalissuearticles values(462%);, SOD insert ignore into journalissuearticles values(56%);, POD insert ignore into journalissuearticles values(100%);, and APX insert ignore into journalissuearticles values(381%); antioxidant enzyme activities were increased in parallel with the salt concentration. In addition, it was determined that as the salt stress increased, the water-soluble protein content decreased by 48%. In the study, it was determined that the seeds were relatively resistant to 100, 150, and 200 mM NaCl salt concentrations, and germination continued. As a result, it has been understood once again that our country has been feeling a negative impact lately, and the determination of alternative plants for growing oily plants has gained more importance in these days. Safflower, which is one of these plants, is a strategically important species both in terms of its oil content and being a source of biodiesel. This study carried out in this context will be a resource for our farmers regarding future studies on safflower seeds and which salt concentrations can be used for cultivation.
