Prevalence of major wood-decay Agaricomycetes in artificial, managed near-natural and undisturbed forests of South Moravia, Czechia

Popis výsledku v původním jazyce

Most wood-decay fungi contribute to the healthy functioning of forest ecosystems, whereas others cause infectious diseases of woody plants and high economic losses for forest management. In this study, we pursued the hypothesis that pathogenic wood-rotting Agaricomycetes occur less frequently in undisturbed forests than in managed stands, especially artificial monocultures. The prevalence of two important pathogens, Armillaria spp. and Heterobasidion annosum s.l., was assessed in managed and unmanaged beech, oak and mixed forests, and spruce plantations in South Moravia, Czechia. In addition, the presence of saproparasitic fungi in decayed wood was examined. Identification of fungal species from wood, soil, basidiome and rhizomorph samples was performed by DNA-based methods. Possible ecological patterns in the distribution of fungi were investigated. Armillaria spp. were ubiquitous; A. cepistipes seems to act as a decomposer, A. gallica is potentially hazardous to oak stands, while A. ostoyae threatens spruce plantations. Basidiomes and epiphytic rhizomorphs of Armillaria were absent in unmanaged stands. Heterobasidion annosum s.s. and H. abietinum basidiocarps were present in 21% and 4% of managed stands, respectively, mostly on conifer stumps. Fomitopsis pinicola, Schizophyllum commune and Stereum spp. were detected in a wide range of hosts and stand types. The results indicate that near-natural forests are less endangered by root rot disease than monoculture plantations.
