Ps. Dyer et al., Development of apothecia of the eyespot pathogen Tapesia on cereal crop stubble residue in England, PLANT PATH, 50(3), 2001, pp. 356-362
A reservoir of infection of Tapesia yallundae may exist after harvest in ba
ses of cereal stems due to the presence of apothecia capable of discharging
infective ascospores. Apothecia of T. yallundae developed in a seasonal pa
ttern on winter barley inoculated with the pathogen, with maximum numbers o
f apothecia produced on stubble 5-7 months after harvest. A similar pattern
of development was observed on infected winter wheat. However, the peak in
numbers of mature apothecia was observed 2 months later than in winter bar
ley. Apothecia capable of discharging ascospores were present for up to 6 m
onths on stubble. Apothecia of T. acuformis were not detected on spring or
winter barley, or spring or winter wheat stubble, despite inoculation of gr
owing crops with isolates of compatible mating type.
