The treatments included aging seed in two levels (unaged seeds and aged seeds) and priming at seven levels (control, distilled water, 25, 75, 50, 100, 125 mg/L with ellagic acid). A pilot study as a factorial experiment with a completely random-base design (CRD) in three replications was carried out under a germinator environment in accordance with standards. To prepare aged seeds in the laboratory, the seeds were incubated at 41°C and 95% relative humidity for 72 hours. Seed priming was soaking with ellagic acid for 6 hours in accordance with the principles of seed aeration. The aging reduced Vigor Index, Allometric Growth Ratio and Seed Reserves Use Rate. The increasing of the malondialdehyde had a negative effect on germination percentage through the influence of Vigor Index and α-amylase activity enzyme. The application of ellagic acid increased the germination percentage in unaged seeds and aged seeds through increasing the activity of α-amylase activity enzyme. The priming of seeds with ellagic acid reduced the malondialdehyde and electrical conductivity. Based on the results of research, the application of 50 mg/L of ellagic acid can be introduced as the best concentration of this material. It can also be suggested that the use of ellagic acid as a seed priming improves the effects of seed aging on soybeans.
