Influence of Nanocompositions Based on Light Fullerene Derivatives on Cultural Plants under Favorable and Stress Conditions of Their Habitat.

The relevance of the new forms of ecologically safe, stable in composition, in functional activity, biodegradable preparations development with a complex positive effect on plants remains high and the presented work is devoted to acquaintance with the generalized results of interdisciplinary studies for the effect on the system of soil (soil substitute)—cultivated plants by nanocompositions created based on carbon (water-soluble polyhydroxylated, carboxylated and amino acid derivatives of fullerene C60) nanostructures with additions of trace elements in certain concentration ratios. Based on the previously identified concentration ranges of the tested fullerene derivatives with a positive effect on plants when treating their seeds, introducing them into the soil, other root habitats and foliar exposure, their compositions with salts of trace elements were developed and in a series of vegetation and field experiments under controlled favorable conditions and when modeling oxidative stress caused by UV-B irradiation, deficiency of soil moisture, deficiency of nutrients, phytopathogens, as well as in the natural conditions of the Leningrad region, the main mechanisms of positive impact (regulatory on vital systems, adaptogenic, immunomodulatory, protective) of the created nanocompositions on plants and the prospects of their application in plant growing are shown.
