In this study, the effect of different doses (0 (control), 50, 100, 200 ppm) gibberellic acid (GA3) treatment on the germination properties of Arısoy (C1), Crawford (C2) and Samsoy (C3) soybean cultivars were investigated. The experiments were factorial arranged in a completely randomized design with four replications. As a result of this study, final germination percentage (FGP), mean germination time (MGT), germination index (GI) value, germination energy (GE) value, seedling vigor index (SVI) value, seedling fresh weight (SFW), seedling dry weight (SDW) and seedling length (SL) were determined between 82-93%, 3-4.43 days, 27.8-37.3, 72-93%, 533-988, 0.57-0.71 g, 0.13-0.21 g, 6.5-10.6 cm, respectively. In terms of FGP, MGT, GI, GE, SVI, SL, SDW properties, a significant difference (P<0.01) was determined between cultivars, GA3 doses and cultivar x GA3 doses. Among the GA3 dose treatmens, FGP, GE, SVI, SL values with 100 ppm GA3 treatment and GI values with 150 ppm GA3 treatment reached the highest levels. MGT value was determined at the lowest 150 ppm GA3 treatment dose. Germination parameters were negatively affected with 200 ppm GA3 treatment dose. Responses of cultivars to GA3 doses were variable. In conclusion, seed priming with gibberellic acid (GA3) can be used to enhance germination properties of soybean cultivars.
