20.500.12556/DiRROS-17988 Patogenost izolatov izbranih vrst gliv na Pinus sylvestris L. IN P. nigra Arnold Pathogenicity of selected fungal species isolates on Pinus sylvestris L. and P. nigra Arnold Na sadikah rdečega in črnega bora smo testirali patogenost osmih izbranih izolatov gliv (Corinectria fuckeliana, Diaporthe eres, Diplodia pinea, Fusarium sp. 1 in 2, Fusicolla sp., Nectria dematiosa in Tympanis sp.), ki smo jih izolirali iz obolelih borovih dreves v Sloveniji v letih 2020 in 2021. Inokulirali smo skupno 115 sadik borov (vključno s kontrolo), periodično smo preverjali njihovo zdravstveno stanje in ob prvih znakih sušenja opravili reizolacije iz robov nastalih nekroz. Reizolacije so bile uspešne le v primeru inokulacije z vrstami gliv Diplodia pinea, Diaporthe eres in Fusarium sp. 2. Povprečna dolžina nekroz sadik rdečega bora, inokuliranih z D. pinea, Di. eres in Tympanis sp., se je statistično značilno razlikovala od kontrolnih sadik (p < 0,05). Pri sadikah črnega bora pa so se za statistično značilne izkazale povprečne dolžine nekroz pri kontroli in inokulacijah z glivama D. pinea in Tympanis sp. (p < 0,05). The pathogenicity of eight selected fungal isolates (Corinectria fuckeliana, Diaporthe eres, Diplodia pinea, Fusarium sp. 1 and 2, Fusicolla sp., Nectria dematiosa and Tympanis sp.), isolated from diseased pines in Slovenia in 2020 and 2021, was tested on seedlings of Scots and Austrian pine. We inoculated a total of 115 pine seedlings (including the control group), regularly checked their health status and performed re-isolations from necrotic margins at the first signs of desiccation. Re-isolations were successful only when inoculated with Diplodia pinea, Diaporthe eres and Fusarium sp. 2. The average length of necrosis in Scots pine seedlings inoculated with D. pinea, Di. eres and Tympanis sp. was significantly different from that of the control group (p < 0.05). In Austrian pine seedlings, the average length of necrosis differed significantly between the control group and seedlings inoculated with the fungi D. pinea and Tympanis sp. (p < 0.05). test patogenosti reizolacije Pinus sylvestris rdeči bor Pinus nigra črni bor pathogenicity test reisolations Pinus sylvestris Scots pine Pinus nigra Austrian pine true false true Slovenski jezik Angleški jezik Neznano 2024-01-25 12:37:15 2024-01-25 12:37:15 2024-01-26 03:50:48 0000-00-00 00:00:00 2023 0 0 str. 1-12 Vol. 132 2023 0000-00-00 Zaloznikova Objavljeno NiDoloceno 0000-00-00 0000-00-00 0000-00-00 630*44:630*17(045)=163.6 2335-3112 10.20315/ASetL.132.1 180298499 https://doi.org/10.20315/ASetL.132.1 1 17a044ef-bb76-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24405 RAZ_Brglez_Ana_2023.pdf RAZ_Brglez_Ana_2023.pdf 1 3110653B0D7A667368D55E2F733DE06D 60faa84772522e89fc1c74c56ce67792c93db822386bef1c513104560f70a21b 3d3b9ce1-bb76-11ee-b0d4-001a4af901a5 https://dirros.openscience.si/Dokument.php?lang=slv&id=24407 Gozdarski inštitut Slovenije Acta Silvae et Ligni 0 0 0
