EVALUATION OF THE EFFECT OF SILICON OXIDE NANOPARTICLES OF DIFFERENT ORIGIN ON THE PRODUCTION OF SOME PRIMARY AND SECONDARY METABOLITES IN PLANTS OF THE FAMILIES FABACEAE, POACEAE

Scientists in different countries are conducting research on assessing a possibility of using silicon nanoparticles in various fields: medicine, pharmacy, medicinal crop production, etc. The work presents results of evaluating an influence of nanoparticles of different origin on production of primary and secondary metabolites. Nanoparticles, obtained from monomineral sand of natural origin, have been shown to increase production of primary and secondary metabolites in plants of the Poaceae family, as well as a content of a sum of chlorophylls, carotenoids, flavonoids, hydroxycinnamic acids, α- and β-chlorophylls and a majority of amino acids contained in leaves of Avena sativa (Poaceae) and Triticum aestivum (Poaceae). Nanoparticles, obtained from synthetic quartz glass, influence production of only primary metabolites, an increase in a content of silicon and some amino acids in leaves and stems of Triticum aestivum (Poaceae).An effect of nanoparticles of different origin on a dynamics of accumulating sum of flavonoids and hydroxycinnamic acids by the example of the Fabaceae family has shown their increase in samples, collected at the beginning of a vegetation season. Morpho-structural analysis of nanoparticles of different origin has revealed differences in a morphology of particles, polymerization of silicon-oxygen chains, which probably explains the presence of distinctive features of a structure and peculiarities of their influence on production of metabolites in plants.
