Quality of winter wheat grain depending on the development of pathogenic mycoflora

One of the main conditions for cultivating grain crops is the production of high yields of high quality grain. However, even well-formed healthy-looking seed are not always of good quality. Wheat grain infestation with mycoflora occurs at different times, e.g. in the period of vegetation, during harvesting, especially in conditions of high humidity, during threshing, during storage of seeds with high humidity. Mycoflora on the seeds can be saprophytic (penicillas, mucor, alternaria, aspergillas, etc.) and pathogenic (helminthiosporium, fusariosis, septoriosis, etc.). The purpose of our research was to study the level of winter wheat infestation with pathogenic microorganisms, to determine their species composition and to investigate whether the level of grain infestation affects protein and gluten content. The species composition of the epiphytic mycoflora of winter wheat grain during the harvesting period and its influence on the food quality of grain are studied, measures are taken to limit its harmfulness.
