Popis: | The aim of the research was to check whether the healing of bark-stripping wounds of the silver fir tree trunks reduces the share of wood-decomposing fungi, which may be the result of inter-species interactions. The study carried out in Gorce National Park in Polish Western Carpathians analyzed drill holes of sapwood from three types of wounds (fresh, healed and old) on fir trunks with a diameter at breast height (DBH) of 4.0–16.9 cm as a result of bark-stripping by red deer (Cervus elaphus). In the wood of fresh wounds Alternaria alternata (Fr.) Keissl. and Arthrinium arundinis (Corda) Dyko & B. Sutton had the largest share in mycobiota. Phompsis spp. and the species Sydowia polyspora (Bref. & Tavel) E. Müll. and Epicoccum nigrum Link were also isolated. The dominants in old wounds were Eutypa spp., Phomopsis spp. and Cylindrobasidium evolvens (Fr.) Jülich. Healed wounds were dominated by Trichoderma atroviride P. Karst, a fungus antagonistic to many fungal pathogens. Such properties are shared by A. arundinis, especially common in fresh wound wood. It seems that these fungi support the process of wounded tree regeneration (healing of wounds) and limit the activity of wood-decaying fungi in old age, which makes fir survival very high. Thus, even a strong red deer pressure cannot be considered the basic factor determining the dynamics of fir in this part of the Carpathians. |
