Özet

We investigated an Armillaria root disease centre in a 60-year-old, naturally regenerated Pinus sylvestris stand located at 1250m altitude in Sinop province in northern Turkey. Based on sequence analysis of the internal transcribed spacer region of the rDNA, the mycelial fans sampled from the infected trees were Armillaria ostoyae. Multilocus genotyping indicated that the fans belonged to a single genet, at least 0.2ha in size. Drought as a predisposing factor is discussed. The study area received 50-70 and 25-50% of the normal precipitation in May, June and August in 2009 and in August and September in 2010, respectively. Moreover, earlier excavation work to prepare a forest road had probably disrupted the water table in the affected stand. © 2012 Blackwell Verlag GmbH.
