Abstract
Uredospores of a barley isolate ofPuccinia striiformis West. were germinated on glucose peptone agar and the development of colonies was observed with a microscope. A small number (0.1–1%) of germ tubes did not abort during the first 20 h of incubation and either differentiated an infection structure or continued slowly to elongate for several days. In 4 out of 9 experiments some of these sporelings produced colonies that reached maximum size (0.15–0.20 mm) after 3 weeks at 15° C.
