Variability in wood anatomical characteristics in silver fir and European beech at three different sites in the Carpathian Mountains

Original language description

Although the general anatomical features are species-specific and thus genetically determined, their actual characteristics vary in different parts of xylem rings within internally determined limits due to various external factors (Rathgeber 2017). The structural adjustments of wood to environmental cues play a decisive role in defining wood&apos;s hydraulic and mechanical properties and, consequently, in tree performance and survival (Chave et al. 2009). In addition to dendrochronology, quantitative wood anatomy has been shown to provide valuable information on how trees adjust their anatomical structure in response to changing environmental conditions (von Arx et al. 2016). Variability in wood anatomical traits and their relationships with environmental factors have not been analysed in silver fir. However, similar studies have been carried out on other conifer species; Ziaco et al. (2014) investigated the effect of drought on different pine species and found significant effect of precipitation on cell enlargement and thus on the final size of tracheids. Furthermore, Castagneri et al. (2017) found that the effect of temperature and precipitation on cell morphology (i.e. cell lumen size and wall thickness) changes during the growing season. Variability in beech anatomical characteristics has recently been investigated using data from beech provenance trials (Eilmann et al. 2014; Hajek et al. 2016). Eilmann et al. (2014) confirmed that southern beech proveniences respond differently to drought conditions compared to northern proveniences, suggesting genetic control of xylem performance in beech. Hajek et al. (2016) observed that beech responded to drought by adjusting vessel number, but not vessel diameter. Similarly, Prislan et al. (2018) recorded differences in vessel density between sites with different weather conditions, while differences in vessel dimensions were not significant. Arnič et al. (2021) found differences in growth and wood anatomical characteristics of beech growing in different forest sites in Slovenia. They concluded that changes in temperature and precipitation regimes, as predicted by most climate change scenarios, will affect tree ring growth and wood structure in beech. The aim of the study was to evaluate the effect of site conditions at three different sites in the Carpathian Mountains on wood anatomical characteristics of European beech and silver fir. We hypothesised that wood anatomical characteristics (i.e. cell size, cell wall thickness, density and distribution of water conducting cells) would differ between the eastern and western populations of fir and beech. The assessment of variability in radial growth and wood anatomical characteristics at the selected sites may be crucial in assessing the range of plasticity in the species under different environmental conditions as a first step in predicting their responses to future climate scenarios.
