| dc.description.abstract | Septoria leaf spot and stem canker, caused by the fungal pathogen Mycosphaerella
populorum Thompson (Anamomorph = Septoria musiva Peck). An efficient greenhouse disease
resistance screening is essential for the development of resistant clones. Fourteen clones of
hybrid poplar were inoculated with spore suspension. A regression model with parameters
(lesion number and proportion necrotic area) is consistently and accurately predicted field
resistance categories of the most resistant and susceptible clones. In second experiments, the
infection biology of S. musiva was examined at several time points by scanning electron
microscopy (6 h, 12 h, 24 h, 72 h, 1-week and 3-week) and histological analysis (3-week, 5-week
and 7-week). Results indicated that there are differences occur following penetration between the
resistant and susceptible. Those differences provide the first clues elucidating resistance
mechanism in hybrid poplar stems. The results from this thesis will be used to improve resistance
to Septoria canker in breeding programs. | en_US |
