Abstract
The aim of the investigations was to determine the differences in colonization of grains of naked and husked oats dependent on the system of plant protection during plant vegetation. The grains of naked oat var. Akt and husked oat var. Hetman were harvested in the field experiments conducted at the Experimental Station in Swadzim in the years 2000–2001. The grains were germinated on Petri dishes with PDA medium. Fungal colonies grown on the grains were examined to identify the species and evaluate a number and type of the colonies. Both the energy and capacity of germination of husked oats were higher than those of naked oats. Saprophytic fungi were found to be in the prevalence (60–80%) among the isolated ones. Pathogenic fungi occurred more frequently on husked oat grains. A significant interaction was stated between presence of husk and system of plant protection
