Abstract

Morphological variation of germ tubes originating from aeciospores of Peridermium pini and Cronartium flaccidum populations on Pinus sylvestris was investigated in rust populations from Finland, the United Kingdom and Italy. The observed morphological variation was generally higher among than between these rust populations. The variation in germ tube length of the rust samples was high over the incubation period. Peridermium pini could not be distinguished from C. flaccidum based on its germ tube morphology.
