Distribution of fungi of the genus Alternaria in Black Point-infected wheat seeds in the Czech Republic

Original language description

The aim was to study the species diversity and ratio of species of the genus Alternaria in wheat seeds with black germ, to determine their potential danger. Identification of fungi of the genus Alternaria was carried out based on the morphological and cultural characteristics of colonies on PCA, the size and structure of conidia, and the sporulation habit. The most frequently identified species were those belonging to the section Alternata, including Alternaria arborescens, Alternaria alternata and Alternaria tenuissima. Their share in the population was 85,8% in 2021 and 96,5% in 2022. The species A. arborescens occupied a dominant position (47-49%) among fungi of this genus in the Alternaria population in the Czech Republic.
