This study was conducted to determine the effects of various pre-treatments on germination percentage (%) and mean germination time (days) in safflower seeds. The experiment was established in 2025 at the Ege University Seed Technology Application and Research Center (TOTEM) laboratories in Completely Randomized Plot Design with three replications. In the study, GA₃ (500 mg L⁻¹), NaCl (10 g L⁻¹), PEG 6000 (300 g L⁻¹), and their combinations (PEG 6000 + GA₃, PEG 6000 + NaCl) were applied as pre-treatments to the seeds. Following the treatments, germination tests were conducted in accordance with ISTA rules; the data obtained were subjected to analysis of variance (ANOVA), and the means were compared using the LSD test. The results revealed statistically significant differences among treatments in terms of both germination percentage (%) and mean germination time (days). The highest germination percentage (90.00%) was obtained from the PEG 6000 + GA₃ treatment. In terms of mean germination time, the shortest duration was determined in the PEG 6000 + GA₃ treatment (3.72 days). In conclusion, the combination of PEG 6000 and GA₃ was found to be the most effective pre-treatment in enhancing and accelerating germination in safflower seeds under laboratory conditions.
