Abstract:Anatomija lesa in floema drevesnih vrst, ki sobivajo, ponuja dragocene informacije o tem, kako se različne drevesne vrste soočajo s podnebnimi spremembami in prilagajajo strukturo prevodnih tkiv lokalnim vremenskim razmeram. V obdobju 2019–2021 smo proučili in primerjali širino letnih prirastkov lesa in floema in velikosti prevodnih elementov ranega lesa in ranega floema pri listavcih, ki sobivajo na Podgorskem krasu: mali jesen (Fraxinus ornus), puhasti hrast (Quercus pubescens) in črni gaber (Ostrya carpinifolia). Ugotovili smo, da analizirane spremenljivke lesa in floema pri preučevanih drevesnih vrstah kažejo različne sezonske trende glede na lokalne vremenske razmere. Med vrstami so bile v vseh letih opažene statistično značilne razlike v velikostih prevodnih elementov lesa in floema, kar kaže na velike razlike v izračunani hidravlični prevodnosti med drevesnimi vrstami. Visoka medletna variabilnost in vrstno specifična občutljivost ksilema in floema na padavine in temperaturo potrjujeta visoko plastičnost in različne strategije debelinske rasti preučevanih drevesnih vrst, ki zagotavljajo optimalno delovanje v lokalnih vremenskih razmerah.

Abstract:The xylem and phloem anatomy of co-existing tree species provides valuable information on how different tree species face climate change and adjust their vascular structure to local weather conditions. We examined and compared annual ring widths and conduit size in earlywood and early phloem in Fraxinus ornus, Quercus pubescens and Ostrya carpinifolia in a sub-Mediterranean site Podgorski kras in the period 2019–2021. We found that phloem increment widths and conduits in earlywood and early phloem in the studied tree species showed different trends in terms of interannual variability and in relation to local weather conditions. Statistically significant differences were observed among species across all years for the size of xylem and phloem conduits and the hydraulic conductivity of earlywood vessels, which indicates great differences in the calculated hydraulic conductivity among the tree species. High interannual variability and species-specific sensitivity of xylem and phloem traits to precipitation and temperature confirm high plasticity and different radial growth strategies of the studied tree species to ensure optimal functioning under local weather conditions
