Description
Summary:The results of laboratory studies on the toxin-forming genus Fusarium fungi are presented in the article. Fungal toxins are metabolites of various chemical nature, usually non-protein, often secondary, having more or less specific pathological effects on the human body, higher animals, plants and microorganisms. The toxins of the genus Fusarium fungi affecting cereal plants are well known. However, the ability to toxin formation varies among different populations of species in this genus. The high degree of cereal infection rate in Siberia with soil phytopathogens can be the reason for their low yield, as well as pose the danger when using cereals affected by toxin-forming fungi in the food industry and in the animal feed preparation. Therefore, the study of toxins produced by Siberian strains of the genus Fusarium fungi is a necessary step for certification of the seed fund in Siberia. The analysis of the obtained materials shows that the most toxic are the metabolites of Fusarium strains 2, 3, 4, 5, T13m, Z2-04, T2ec, J1kc, B-7.1(b), B-1.2, B-3.2(C), B-6.1, B-4.2, since less than 25% of barley seeds germinated when they were processed with these metabolites. The metabolites of j7ec, B-7.1(K) strains are not toxic to barley seeds.
