1. Patogenost izolatov izbranih vrst gliv na Pinus sylvestris L. IN P. nigra ArnoldAna Brglez, Barbara Piškur, Nikica Ogris, 2023, izvirni znanstveni članek Povzetek: 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).

2. Description, identification, and growth of Tuber borchii Vittad. mycorrhized Pinus sylvestris L. seedlings on different lime contentsTanja Mrak, Tine Grebenc, Silke Friedrich, Babette Münzenberger, 2024, izvirni znanstveni članek Povzetek: Tuber borchii forms ectomycorrhiza with oaks, hazel, and pines, including Pinus sylvestris. However, its ectomycorrhiza morphotype with P. sylvestris was not comprehensively described so far, and molecular analyses are missing despite a high danger of misidentification of T. borchii ectomycorrhiza with other closely related and less valuable truffle species. We described for the first time the morphology and anatomy of T. borchii-P. sylvestris ectomycorrhiza using differential interference contrast technique and semi-thin sections in combination with molecular confirmation of identity. Color of ectomycorrhiza is reddish to dark brown, and morphotypes are unevenly but densely covered by warts-bearing pin-like cystidia. All layers of the hyphal mantle are pseudoparenchymatous with outer mantle layer formed of epidermoid cells. T. borchii ectomycorrhiza was identified by a molecular comparison with fruitbodies used for inoculation and its respective ectomycorrhizae. T. borchii has a wide ecological amplitude. To get a better insight in mycorrhization requirements, we investigated growth of P. sylvestris and its ectomycorrhiza infection rate with T. borchii in substrate with different lime content. The mycorrhization of P. sylvestris with T. borchii in the mycorrhization substrate and cultivation in greenhouse conditions was successful, with colonization of P. sylvestris varying between 36.5 and 48.1%. There was no significant correlation of mycorrhization to applied lime contents, and consequently to pH in substrate, while the increased levels of lime improved growth of the P. sylvestris seedlings.

9. Local site conditions reduce interspecific differences in climate sensitivity between native and non-native pinesMarcin Miroslav Klisz, Radosław Puchałka, Marcin Jakubowski, M. Koprowski, Maksym Netsvetov, Yulia Prokopuk, Jernej Jevšenak, 2023, izvirni znanstveni članek Povzetek: Two European pine species, Pinus sylvestris and Pinus nigra, are experiencing dieback as a result of the increasing frequency and intensity of extreme climatic events. Recent species distribution models predicted shrinkage of ecological niches in the near future and shifted their habitat range towards the northeast. Consequently, P. sylvestris may contract its range and P. nigra may expand in Central Europe. To test whether native pine species have an advantage over introduced pine species in acclimation to a novel climate in Central Europe, we investigated the climate sensitivity and vitality of P. sylvestris, P. nigra and P. rigida. We sampled mature stands of each pine species at three sites in Central Europe, for which we determined climate–growth relationships: temporal stability of temperature and precipitation correlations with tree-ring width and resilience indices. Based on remote sensing data, we assessed differences in surface reflectance and photosynthetic activity obtained from the normalised difference vegetation index (NDVI). Our analyses revealed that the climate sensitivity and surface reflectance of pines are not due to their nativeness in Central Europe but better explained by local site conditions. The specificity and variability of drought events may determine both the homogeneous and diverse susceptibility of species to a negative water balance. Therefore, the character of future climatic extremes seems to be the key to understanding the acclimation of native and non-native pine species in Central Europe. Because our study do not provide evidence of the superiority of non-native pine species over P. sylvestris, and the potential impacts of introduced species on local habitats seem poorly understood in the face of climate change, we urge particular caution in introducing species with unrecognized invasive potential.
