IN P. nigra Arnold| Pathogenicity of selected fungal species isolates on Pinus sylvestris L. and P. nigra Arnold|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)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.
