At present, rapid development of nanotechnology requires assessment of their effects on plants, interaction with plant cells and concentration dependence. The degree of toxicity of nanocompounds affecting plants depends on physical properties of nanoparticles (dimension, shape, catalytic activity, concentration). The research objects were Tarasov potato tubers treated in Fe° (90-110 Nm) and Cu° (50-110 Nm) NPs at four concentrations with a geometric progression (0,0125; 0,025; 0.05 and 0.1 M). The aim of the research is to study the effect of iron and copper metals on the activity of Solánumtuberósum L. antioxidant protection of plants. The Fe 0 NPs caused oxidative stress and decreased the content of MD (1.3 - 26.7%) and phenolic compounds with a simultaneous increase in peroxidase. After exposure to Cu 0 nanoparticles, there was a redox imbalance in the roots and sprouts which manifested itself as a decrease in CAT (7.4-36.7%) and FS (19.1 - 34.0%) activity with a sharp increase in the content of MD and an increase in peroxidase activity.
