20.500.12556/DiRROS-15505 First report of Diplodia fraxini and Diplodia subglobosa causing canker and dieback of Fraxinus excelsior in Slovenia Over the last decades the vitality and productivity of European ash trees in Slovenia has been seriously impacted by the onset of canker and dieback disease symptoms on young and old trees, primarily identified as ash dieback caused by Hymenoscyphus fraxineus. Given the limited information available about the aetiology of this emerging disease, a study was carried out to isolate, identify and characterize the fungal species involved in the observed ash symptoms. Field surveys were conducted in five forest sites where 50 symptomatic branch samples were collected. All samples were inspected and used for fungal isolation. Based on morphology, colony appearance and DNA sequence data of the internal transcribed spacer region (ITS), 125 fungal colonies belonging to five species were isolated and identified. Only a few symptomatic ash samples yielded colonies of H. fraxineus, whereas Botryosphaeriaceae species were isolated with a high frequency, with Diplodia fraxini as the dominant species. A pathogenicity test proved that all isolated species were pathogenic on European ash, causing bark lesions and wood discoloration. All Botryosphaeriaceae species isolated in this study are reported for the first time on European ash in Slovenia. emerging disease invasive species Botryosphaeriaceae pathogenicity invazivne vrste prvo poročilo Botryosphaeriaceae patogenost varstvo gozdov true false true Angleški jezik Slovenski jezik Neznano 2022-09-15 09:27:23 2022-09-15 09:27:23 2022-09-16 03:36:01 0000-00-00 00:00:00 2022 0 0 Avtorji iz Slov.: Ana Brglez, Barbara Piškur, Nikica Ogris; str. 26-29 iss. 1 Vol. 106 2022 0000-00-00 PostprintKoncna Objavljeno NiDoloceno 0000-00-00 0000-00-00 2022-01-01 2023-01-22 630*44 0191-2917 10.1094/PDIS-06-21-1204-SC 77954563 https://apsjournals.apsnet.org/doi/10.1094/PDIS-06-21-1204-SC 1 1b954f18-34b7-11ed-bea5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20513 RAZ_Linaldeddu_Benedetto_Teodoro_2022.pdf RAZ_Linaldeddu_Benedetto_Teodoro_2022.pdf 1 4920A87BD0D85571246B702CE7E63AB5 3a8797c3e3b18fbdcb5a9673dd0503a716c18a674add4031e007e45cf2bcad56 7b61178d-34b7-11ed-bea5-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=20515 Gozdarski inštitut Slovenije 0 0 0
