20.500.12556/RUL-173125 Vpliv poudarjenosti socialnih funkcij in drevesne sestave gozda na donose trosnjakov izbranih vrst gliv na območju južnega Pohorja The influence of social functions and tree species composition of forests on yield of selected fungi species in the southern Pohorje region Raziskava obravnava vpliv poudarjenosti rekreacijske funkcije in drevesne sestave gozda na donose trosnjakov treh tržno zanimivih mikoriznih gliv poletnega gobana (Boletus reticulatus), jesenskega gobana (Boletus edulis) in navadne lisičke (Cantharellus cibarius). Raziskava je bila izvedena na območju Južnega Pohorja, kjer je bilo postavljenih 42 raziskovalnih ploskev v gozdovih z različno poudarjenostjo rekreacijske funkcije in različnimi prevladujočimi drevesnimi vrstami (bukev, smreka, rdeči bor). V rastni sezoni 2024 je bilo sistematično beleženo število nabranih trosnjakov, iz česar so bili izračunani masni in vrednostni donosi, slednji ovrednoteni z upoštevanjem aktualnih tržnih cen. Analiziran je bil tudi vpliv padavin in luninega cikla. Skupni povprečni masni donos je znašal 29,0 kg/ha, vrednostni pa 469 €/ha. Rezultati raziskave niso pokazali statistično značilnega vpliva rekreacije na donose gliv, so se pa nakazali trendi, da poletni in jesenski goban slabše uspevata na območjih s poudarjeno rekreacijsko funkcijo, medtem ko se je navadna lisička pogosteje pojavljala prav tam. Donosi so se razlikovali tudi glede na drevesno sestavo. Jesenskemu gobanu so najbolj ustrezali smrekovi sestoji, poletnemu gobanu in lisički pa bukovi in sestoji rdečega bora, vendar tega nismo uspeli statistično potrditi. Vpliv padavin se je izkazal kot pomemben pri navadni lisički, medtem ko je polna luna statistično značilno vplivala na donos jesenskega gobana. Ugotovitve prispevajo k razumevanju vpliva socialnih in naravnih dejavnikov na rast mikoriznih gliv in poudarjajo njihov ekonomski potencial kot postranski gozdni proizvod v okviru trajnostnega gospodarjenja z gozdovi. The research investigates the impact of forest recreational function and tree species composition on the yield of fruiting bodies of three economically important ectomycorrhizal fungi summer cep (Boletus reticulatus), porcini (Boletus edulis), and chanterelle (Cantharellus cibarius). The study was conducted in the southern Pohorje region, where 42 plots were established in forest stands with varying levels of recreational use and different dominant tree species (beech (Fagus sylvatica), spruce (Picea abies), Scots pine (Pinus sylvestris)). During the 2024 growing season, fruiting bodies were systematically recorded. Mass and value yields were then calculated based on current market prices. The influence of precipitation and the lunar cycle was also analyzed. The average yield was 29.0 kg/ha, with an estimated value of 469 €/ha. Although no statistically significant effect of recreation was found, trends indicated lower yields of Boletus species in highly visited areas, while, on the contrary, chanterelles were more abundant there. Tree species composition also affected fungi yields. Porcini thrived in spruce stands, while summer cep and chanterelle performed better in beech and Scots pine stands, though differences were not statistically significant. Precipitation significantly influenced chanterelle yield, and a full moon had a positive effect on porcini yield. The research contributes to a better understanding of how social and environmental factors affect the fruiting of the studied mycorrhizal fungi and highlights their economic potential as non-wood forest products within sustainable forest management. mikorizne glive gozdne funkcije drevesna sestava donos trosnjakov južno Pohorje mycorrhizal fungi forest functions tree species composition fruiting body yield Southern Pohorje true false false [F.
