Phenotypic variation in the phenology of ascospore production between European populations of oak powdery mildew
Original language description
Oak powdery mildew severity (Erysiphe alphitoides) is usually mild in Europe because epidemics start late in spring, at the end of the first oak growth unit maturation. However, the disease can occasionally be very severe when strong infection occurs early during the development of the first growth unit, suggesting that host-pathogen synchrony in spring could be a critical factor in disease severity. We studied the timing of ascospore production in a given environment for four E. alphitoides populationssampled from SW France to the Czech Republic to determine whether this trait shows variation within Europe. Timing of ascospore production was clearly influenced by environmental factors as chasmothecia from a single origin showed very different dates of optimal ascospore production when transferred for overwintering in locations with different climate. In common garden experiments, no differences were observed between populations for the date of optimal ascospore production. Results su
