Evaluation of the effect of SiO2 and Fe3O4 nanoparticles on Pisum sativum seeds in laboratory and field experiments

Abstract

The present study assessed the toxic effects and prospects of using nanoparticles of SiO2 and Fe3O4 by studying the influence of pre-sowing priming of Pisum sativum L. seeds with a suspension of nanoparticles of SiO2 and Fe3O4 in a concentration range of 10-2 to 10-5 mg/l. The results demonstrated the stimulating effect of the SiO2 suspension (10-3 mg/l and 10-4 mg/l) and the mix of Fe3O4+SiO2 at the corresponding concentrations of 10-3 mg/l and 10-4 mg/l on the length of roots and seedlings, and the increase in the viability of plant cells under the influence of a stress factor (based on Evans blue staining). Field experience has shown the ambiguous effect of nano-printing of seeds on plant productivity.
