Key Points

To determine how varying doses of gibberellic acid (GA₃) influence seed germination metrics and early seedling development across multiple soybean varieties.
Treated five soybean (Glycine max L.) varieties—Adel, Ataem-7, Cinsoy, Lider, and Umut 2002—with five GA₃ concentrations: 0, 25, 50, 100, and 200 mg L⁻¹.
Evaluated germination percentage, germination index, average germination time, seedling length, plumule length, radicle length, and seed vigor index.
Soybean variety, GA₃ dose, and the variety × dose interaction produced statistically significant differences across germination and seedling growth parameters.
Responses in plumule, radicle, and overall seedling vigor varied significantly depending on the specific combination of cultivar genetics and hormone concentration.
