THE IRON OXIDE (FE2O3NPS) AND GRAPHENE OXIDE (GONPS) NANOPARTICULES PRIMING TREATMENTS ALLEVIATE THE EFFECTS OF SALINITY DURING GERMINATION OF THE SOYBEAN

Nanoparticles containing essential plant nutrients, including micronutrients, can be effective in improving germination characteristics. In the present study, the aim was to evaluate seed germination characteristics by priming application. The study was conducted at the Field Crops Laboratory, Faculty of Agriculture, Adnan Menderes University. For this study, the germination characteristics of soybean seeds were investigated in four different priming treatments (control, Fe2O3NPs, Graphene oxide, Potassium humate) in both saline and non-saline conditions. The results of the study showed that Fe2O3NPs, graphene oxide, and potassium humate had positive and significant effects under both conditions. It was also determined that saline conditions caused a decrease in the observed properties. Among these priming treatments, almost all traits, such as germination percentage (77.19%), root length (31.74 mm), and hypocotyl length (67.01 mm), were observed in the Iron oxide NPs treatment. The study revealed a significant and positive effect of priming applications on the germination percentage and the examined characteristics in both environments.
