Abstract: 

This experiment was conducted to evaluate seed size (large, medium and small) and salinity (0, 30 and 60mM and 0, 9×10-4 and 18×10-4pa) effects and their interactions on germination traits and seedling growth of soybean cv. KATUL. It was done as factorial experiments in the base of completely randomized design with three replications in seed physiology and technology laboratory of Mohaghegh Ardabili University in 2011. In this experiment coefficient of velocity of germination (CVG) and germination percentage, homogeneity, seedling dry weight, reserve mobilization and its efficiency were examined. According to results, by increasing seed size, germination uniformity decrease significantly. Salinity decreased seedling dry weight, mobilized reserves and its efficiency, significantly. But it didn't have any significant effect on germination percentage, uniformity and CVG. Furthermore, interaction effect of salinity and seed size had significant effect on germination uniformity, seedling dry weight, mobilized reserves and its efficiency. This experiment showed that small seeds had better germination uniformity and getting reserves more and faster than larger ones to seedlings.
