Effects of Accelerated Aging on Soybean Seed Germination Indexes at Laboratory Conditions

Reduction of seedling growth is a consequence of seed deterioration. An experiment was conducted to evaluate the effects of duration of seed aging on soybean seed germination characteristics. Experiment conducted as completely randomized design with 4 replications. The seeds of DPX line of soybean with 15-16% moisture were incubated for 3, 7, 10, 14, 17 day at 40C in sealed containers for ageing treatment and non aged seeds were considered as control. Results showed that rapid aging treatment has a significant effect on studied parameters. Germination percent (GP), means of daily germination (MDG), means time to germination (MTG), coefficient of velocity of germination (CVG) and germination index (GI) decrease significantly. Also, germination uniformity (GU) was affected by deterioration time. Abnormal seedling (ABS) percentage increased. Results shows that rapid aging experiment could be a useful test for determine soybean seed quality
