Jelen munkánkban somogyi kocsánytalan tölgyek és csertölgyek (Quercus petraea, Q. cerris) aszályra adott növekedési reakcióját vizsgáltuk, egy csapadék gradiens mentén. Az értékeléshez 136 évgyűrűmintát használtunk fel, valamint az aszályérzékenység meghatározásához dendroökológiai számításokat végeztünk. A vízhiányt a talaj vízháztartásán alapuló nedvesség-stressz index felhasználásával becsül...

A silane-siloxane based water-repellent substance (S-WR) was used as an impregnation material for Scots pine (Pinus sylvestris L.), black nigra Arnold), sessile oak (Quercus petraea Liebl.), and cedar (Cedrus libani A. Rich). In the process, immersion method carried out various periods (30 min, 3 h, 24 h). Following impregnation, physical properties of wood (retention, contraction, expansion, w...

We investigated light acclimation in seedlings of the temperate oak Quercus petraea (Matt.) Liebl. and the co-occurring sub-Mediterranean oak Quercus pyrenaica Willd. Seedlings were raised in a greenhouse for 1 year in either 70 (HL) or 5.3% (LL) of ambient irradiance of full sunlight, and, in the following year, subsets of the LL-grown seedlings were transferred to HL either before leaf flushi...

The need to understand the carbon sequestration ability of trees under current and future climatic scenarios is fundamental predict role forest in counterbalancing global warming. In this study, we investigated Pinus sylvestris L. a setting pure mixed forests with Quercus petraea (Matt.) Liebl. Central Poland. Beside traditional growth measures, i.e., Ring Width, Basal Area Increment, wood dens...

General Context: Climate change can positively or negatively affect abiotic and biotic drivers of tree mortality. Process-based models integrating these climatic effects are only seldom used at species distribution scale. Objective: The main objective this study was to investigate the multi-causal mortality risk five major European forest across their range from an ecophysiological perspective,...
