o:6859 THE MOST COMMON FUNGI ASSOCIATED WITH A DECLINE OF TURKEY OAK (QUERCUS CERRIS L.) IN URBAN CONDITIONS IN SERBIA NAJČEŠĆE GLJIVE POVEZANE SA PROPADANJEM STABALA CERA (QUERCUS CERRIS L.) U URBANIM PODRUČJIMA SRBIJE en sr Turkey oak (Quercus cerris) is one of the most important tree species in park forests and parks in Serbia. Despite this, there has been no available information in domestic literature about the parasitic fungi that affect Turkey oak in urban areas. Research carried out between 2016 and 2023 identified 19 taxa of parasitic and saprotrophic fungi that colonize Turkey oak in urban conditions: one on the roots, two on the leaves, two on the bark, seven on the trunk, two on the branches, two on the fruits, two on the stumps, and one on both leaves and fruits. The most significant fungi found were Fomes fomentarius, Inonotus nidus-pici, and Fuscoporia torulosa, which cause heart rot and are typically found on individual trees. Most of the fungi identified occurred in succession. Following primary damage, the most frequently occurring fungus was Stereum hirsutum, while after mechanical injuries, Schizophullym commune was most frequently recorded. Alternaria spp. was found on old leaves and heavily damaged leaves. To protect the urban Turkey oak trees, measures should be focused on reducing tree density and preventing mechanical injuries. The findings from this research also contribute to understanding the ecological characteristics of these fungal taxa based on their frequent occurrence in urban conditions Cer (Quercus cerris) predstavlja jednu od najvažnijih vrsta drveća u park šumama i parkovima Srbije. Do sada u domaćoj literaturi nije bilo podataka vezano za parazitski komples gljva koje kolonizuju cer u urbanim uslovima. Istraživanje izvršeno u periodu 2016-2023 je pokazalo 19 taksona parazitskih i saprofitskih gljiva; jedan na korenu, dva na listovima, dva na kori, sedam na deblu, dva nа гранама, dva na plodovima, dva na panjevima i jedan na listovima i plodovima. Najvažnije gljive su bile Fomes fomentarius, Inonotus nidus-pici i Fuscoporia torulosa prouzrokovači centralne truleži, koje su konstatovane na pojedinačnim stablima. Većina konstatovanih gljiva se javljala u sukcesiji. Posle primarnih uzročnika oštećenja, najčešća je Stereum hirsutum, dok je posle mehaničkih oštećenja najčešće konstatovana Schizophyllum commune. Alternaria spp. je zabeležena na starim listovima, kao i posle teških oštećenja listova. Mere zaštite cera treba da budu usmerene u smanjenju gustine i izbegavanju mehaničkog oštećenja stabala. Dobijeni rezultati takođe doprinose poznavanju ekoloških karakteristika taksona gljiva na osnovu njihove česte konstatacije u urbanim sredinama. oak decline, causes, urban areas, first record propadanje hrastova, uzročnici, urbana područja, prvi nalaz 1552101 1821-1046 1552099 10.5937/SustFor2490119V 2025-01-13T13:54:44.985Z 44 yes 46 Aleksandar Vemić 0000-0001-9195-8967 46 Zlatan Radulović 0000-0003-2336-0255 46 Katarina Mladenović 0000-0002-9172-2388 46 Ljubinko Rakonjac 0000-0002-8736-6771 application/pdf 1558464 https://unilib.phaidrabg.rs/o:6859 no yes 16 70 92000001 2024 71A07 Sustainable Forestry: Collection 89-90 119 130 Институт за шумарство, Београд, Србија 2024
