Abstract

The aim of the studies was determination of the ergovaline content in 71 grass samples collected from 24 grasslands, in which hyphae of endophytic fungi were found. Ecotypes of Deschampsia caespitosa, Festuca arundinacea, F. pratensis, F. rubra and Lolium perenne were identified as the hosts. Determination of ergovaline content in biomass of the endophyte — containing (E+) ecotypes was done using the HPLC method with fluorescence detection. Ergovaline was found in 4 of 5 examined grass species earlier classified as the endophyte — infected. D. caespitosa was the only species in which the E+ ecotypes did not produce ergovaline. The ergovaline production showed high qualitative and quantitative variability even within one grass species. The intensity of pasture usage affected ergovaline production by endophytic fungi from the Neotyphodium genus.
