Microscopic observations of germination of teliospores directly after sampling from leaves of two grass species. The grass plants with uredia were labelled in the autumn, 2013 and collected after overwintering in March, 2014. Observations of teliospore germination were performed with a light microscope. a Telial sori on A. cristatum. b Germination of teliospores from A. cristatum. c Telial sori on E. cylindricus. d Germination of teliospores from E. cylindricus. There was no significant difference in teliospore germination of telial samples between A. cristatum and E. cylindricus at the level of 0.05 (P = 0.277)
