Influence of selenium and silicon salts and nanoparticles on the growth of <i>Fusarium avenaceum</i> (Fr.) Sacc. and <i>Bipolaris sorokiniana</i> (Sacc.) Shoem. mycelium and grain seeds germination

Abstract

The effect of selenium and silicon in nanoform in comparison with sodium selenite and sodium silicofluoride on the growth of pathogenic fungi Fusarium avenaceum and Bipolaris sorokiniana was evaluated. The influence of nanoparticles on wheat and corn seed germination and seedling growth was also studied. The inhibitory effect of selenium and silicon nanoparticles on the growth of Fusarium avenaceum and Bipolaris sorokiniana was revealed. Nanosilicon at a concentration of 5–50 mg/l inhibited the growth of pathogenic fungi Fusarium avenaceum and Bipolaris sorokiniana to a greater extent than selenium nanoparticles and was more effective than sodium silicofluoride. Fusarium avenaceum was shown to be more resistant to nanoselenium and sodium selenite compared to Bipolaris sorokiniana. Nanoparticles had practically no effect on seed germination and the growth of wheat and corn seedlings, while sodium selenite and sodium silicofluoride at the same concentrations caused a decrease in seed germination energy and dry weight of the shoots and roots of seedlings.
