Seed germination and growth parameters response of mungbean influence by biogenic fe 3 o 4 nanoparticles

Biotechnology and nanobiotechnology combined may result in rapid and significant development in the area of agricultural industry for their efficient delivery and production of copious nutritious food. Engineered iron oxide nanoparticles have been used extensively for environmental remediation. Plants are an important component of ecosystems and can be used for the evaluation of overall fate, transport and exposure pathways of iron oxide nanoparticles in the environment. In this work, the effect of engineered iron oxide NPs on the germination and growth of mungbean is studied. The influence of graded concentrations (0, 50, 100, 150 and 200 mg.L-1) of nanosize iron oxide were studied on seed germination parameters including germination percentage (GP %), Fresh Biomass Weight (FBW), Fresh Shoot Weight (FSW), Fresh Root Weight (FRW), Dry Shoot Weight (DSW), Dry Root Weight (DRW) of mungbean plant. Results indicated that significant differences in examined traits were found among the plant species and also among the employed iron oxide concentrations. The highest GP (90%) was observed in 100 mg.L-1 concentration, however, the lowest GP (80%) it was obtained at control. In conclusion, application of iron oxide stimulated the seed germination of mungbean plant. However, this response was dependent on the concentration of applied iron oxide and way of treatment.
