Abstract

The article presents the study of the effect of nanocomposites (NCs) based on selenium (Se), copper (Cu), and manganese (Mn) nanoparticles (NPs) embedded in a matrix of natural polysaccharides—arabinogalactan (AG), carrageenan (CAR), and starch (ST)—on the content of chlorophylls (Chls) and carotenoids in potato tissues in vitro. Potatoes were grown for 28 days on Murashige-Skoog (MS) medium with the addition of a NC, then pigments were isolated from leaf tissues, and their content was determined spectrophotometrically. Both a stimulating effect and an inhibitory effect of different NCs on the pigment content were found. Se and Cu NCs in the AG matrices (Se/AG and Cu/AG NCs) increased the Chl content both in the leaf tissues of healthy potato plants and plants infected with the phytopathogenic bacterium Clavibacter sepedonicus (Cms). Mn NCs increased the content of carotenoids and Chls in potatoes infected with Cms. A decrease in the pigment content was detected when growing potatoes on a medium with the addition of Cu NC based on a ST matrix (Cu/ST NC), which is probably due to the high content of NPs in this NC (20%). It was concluded that NCs based on an AG matrix are capable of exerting a stimulating effect on the content of potato pigments, which can be used to increase the yield of this crop.
