Summary. Interest in the use of ultrafine particles in crop production and agricultural practice is associated primarily with their unique properties. The presented work evaluates the impact of ultrafine particles of silicon dioxide in various concentrations on Solanum tuberosum. The objects of the study were potato tubers of the "Tarasov" variety and silicon dioxide UFPs. The samples were treated with a suspension of SiO2 UFPs at concentrations: 0.03, 0.09, 0.18, 0.21, and 0.36 g / kg of potatoes. During the experiment, the peroxidase activity (according to Boyarkin's method), cell viability according to the manufacturer's protocol (WST-8 patent No. 2.251.850, Canada) and the integrity of the DNA molecules of Solanum tuberosum plants (from plant cells by phenol-chloroform extraction) were determined. According to the results of the study, nanosilica at a concentration of 0.21 and 0.36 g/kg had a statistically significant effect on the number of living cells (there was a decrease to 17.1%). It was revealed that the silicon dioxide UFPs at a concentration of 0.09 and 0.18 g/kg had a significant effect on the peroxidase activity in Solanum tuberosum plants. The results of the studies carried out confirmed the decrease in the intensity of the DNA luminosity peaks by a temporally calculated linear profile at a maximum dilution of 0.36 g/kg.

Key words: potato, silicon dioxide, nanoparticles, potato stress resistance, cell viability, integrity of DNA molecules.
