In article for the first time investigated influence of nanocomposites of selenium in matrixes of an arabinogalaktan (Se/Ag) and starch (Se/St) on vegetation of in vitro plants potatoes, peroxidase activity and reactive oxygen species. Earlier it was shown that these nanocomposites of selenium have antimicrobial effect to a phytopathogenic bacterium of Clavibacter michiganensis ssp. sepedonicus (Cms). In this real work it is shown that the Se/Ag (6,4% of Se) and Se/St (12% of Se) have no negative impact on the healthy and infected with Cms potatoes, stimulating its growth, quantity of leaves and mass of a vegetative part. NC Se/Ag has a positive effect on potato plants by increasing its immune status by increasing ROS content and increasing peroxidase activity. With application of the element analysis it is shown that the studied nanocomposites do not collect in potatoes fabrics after its processing by them. The Se/Ag and Se/St as potential agents for improvement of potatoes from pathogenic bacteria allow to consider the received results.
