Effect of Nanopriming with Selenium Nanocomposites on Potato Productivity in a Field Experiment, Soybean Germination and Viability of Pectobacterium carotovorum

In recent decades, the use of nanocomposites (NCs) in crop production has been actively studied. We have previously shown that chemically synthesized selenium (Se NCs) based on natural polymeric matrices arabinogalactan (Se/AG NCs), carrageenan (Se/CAR and starch (Se/ST stimulated growth development potatoes vitro had an antibacterial effect against phytopathogen Clavibacter sepedonicus. It is important to confirm results obtained laboratory are also reproducible field conditions cultivation. addition, applications NCs can be expanded if a wider range their biological activity revealed, other types cultivated plants phytopathogens shown. this regard, purpose research was study nanopriming with Se productivity experiment, germination soybeans, viability Pectobacterium carotovorum under conditions. The included traditional methods conducting experiment growing conditions, using microbiological cultures studying bacterial profile from endosphere potato tubers by imprint method, germinating Glycine max L. soybean seeds after Petri dishes, followed measurement morphometric biochemical parameters such as antioxidant enzymes content diene conjugates. Based experiments, it found preplant treatment Se/AG Se/CAR significant increase number stems per plant, but for NC, observed only 2020 2022, stimulating weight 2020. yield structure, proportion marketable seed increased influence all NCs. Endosphere showed bacteria were present 56% control, while 78% grown treated NC 100% Se/ST contained bacteria. represented both spore-forming Gram-positive Gram-negative various sizes. presented article published data maximum diversity NC. Experiments greatest effect. growth-stimulating these biomass roots seedlings activated reduced level conjugates (DCs), amount which significantly biopriming carotovorum. relation P. reduction culture, biofilm formation, dehydrogenase cells. Thus, agriculturally crops well phytopathogenic
