Disease symptoms and fungi occurring on overground organs of Quercus petraea

Krystyna Przybył


The observatins of Quercus petraea trees growing in mixed forests of Wielkopolska National Park and Wolin National Park were carried out in 1994 and 1995. The fungi were isolated from dead sections of twigs and branches and from trunks exhibiting necrosis in secondary bark and discolorations of sapwood. Thirty one fungal species were identified on the organs studied. They belonged to saprophytes and to the group of fungi secondarily colonizing tissues of weakened trees.
