Abstract:Študija je sestavljena iz treh vsebinsko dopolnjujočih sklopov in daje vpogled v najnovejše odzive bele jelke in navadne bukve na okoljske dejavnike ter vključuje napovedi odziva na podnebne spremembe in prispeva pri oblikovanju gozdnogojitvenih usmeritev za gospodarjenje v prihodnje. Vzdolž gorskega masiva Karpatov od smo izbrali osem lokacij v odraslih, optimalno razvitih gospodarskih jelovo-bukovih sestojih in pragozdnih rezervatih nad 800 m nad morjem. Izmerili smo asimilacijski odziv mladja v treh zaporednih rastnih obdobjih in odvzeli izvrtke 15 dominantnih jelk in bukev na izbranih lokacijah za dendrokronološko in lesno-anatomsko analizo. Največjo asimilacijsko učinkovitost jelke smo izmerili v svetlobnih razmerah pod zastorom matičnega sestoja, pri bukvi pa na odprtem. Tako bukev kot jelka kažeta večjo debelinsko rast z več padavinami v juliju in manjšo rast z večjimi povprečnimi in največjimi temperaturami v juniju tekočega leta. Pri jelki smo potrdili statistično značilno pozitivno korelacijo med debelinsko rastjo in temperaturo pozimi, bukev pa negativno korelacijo med debelinsko rastjo in temperaturo poleti. Severna rastišča postajajo za rast obeh vrst ugodnejša, zlasti za jelko. Pri jelki smo potrdili statistično negativno korelacijo med relativno prevodno površino in gostoto celic, povprečno površino celic in gostoto celic ter srednjo debelino tangencialnih celičnih sten in relativno prevodno površino. Izmerjene lastnosti trahej pri bukvi so v korelaciji s širino branik. Bukev in jelka se odzivata na podnebne parametre na izbranih lokacijah različno, pri čemer je jelka bolj odporna na sušo kot bukev.

Title:Growth responses of silver fir (Abies alba) and European beech (Fagus sylvatica) to climatic factors along the Carpathians : doctoral dissertation
Abstract:The study consisting of three complementary parts provides insights into the updated responses of silver fir and European beech, predicting the response to climate change with basis for silvicultural guidelines for future management. Along the Carpathian Mountains eight permanent plots were established in optimally developed, managed and old-growth beech and fir forests above 800m ASL. The assimilation responses of young trees were measured in three consecutive growing seasons; 15 dominant fir and 15 beech trees were double cored at every selected location for dendrochronological and wood-anatomical analysis. The maximum assimilation efficiency of fir was confirmed under the mature canopy light conditions and for beech in the open. Both beech and fir show better radial growth with higher precipitation in July and slower growth with higher average and maximum temperatures in June of the current year. Fir shows a positive correlation between radial growth and temperature in winter, while beech shows a negative correlation between radial growth and temperature in summer. Northern sites are becoming increasingly favourable for the growth of both species, especially fir. For fir, there is a negative correlation between the relative conductive surface and the cell density, the average cell surface area and the cell density, and the mean thickness of tangential cell walls and the relative conductive surface. Measured tracheal properties in beech show correlations with tree ring width. Beech and fir respond differently to climatic parameters at the selected sites, with fir being more drought tolerant than beech.
