چکیده مقاله:
Today, nanotechnology has affected all fields of science, especially plant science, and has gained a special status in improving the quality of human life. The role of iron in reducing non-biological stresses has not been widely evaluated despite the fact that it is considered an essential element for plant growth. In this study, the effect of foliar application of iron oxide magnetic nanoparticles (Fe۳O۴) in five concentrations (۰, ۱۰, ۲۰, ۵۰ and ۱۰۰ mg/L) on tomato plant subject to three concentrations of CdCl۲ (۰, ۱۰۰ and ۲۰۰ μM) was assessed. The results showed that cadmium had a negative impact on plant growth and nutrients uptake, so that increasing cadmium concentration led to further reduction in growth parameters; however, ۲۰ mg/L concentration of Fe۳O۴ improved this condition by augmenting nutrient absorption and reducing cadmium uptake. In general, accumulation of nutrients, which is associated with an increase in biomass and subsequent dilution of heavy metal in plant structure, leads to a reduction in the toxicity of heavy metals
