“…Fifteen solitary trees at least 100 years old, denoted WO1 to WO15, were selected according to the ECO strategy described by Zielski and Krąpiec (2004), which partially limits the infl uence of non-meteorological factors on TRWs (Bronisz et al, 2012). After drying and planing, the stem discs were used to measure ring widths along two paths, each from bark to pith, by means of LINTAB TM Kalbarczyk and Ziemiańska (2016). The two tree-ring paths were cross-dated and averaged so that one tree-ring series was available for each of the 15 study trees (WO1 to WO15).…”

“…In parks, the health of this tree species is mainly impacted by three factors: distance from the city center, proximity to thoroughfares, and emissions from the combustion of fossil fuels (Krzyżaniak et al, 2013;Krutul et al, 2014). The correct primary and secondary growth of oak trees in an urban space is also infl uenced by underground technical installations, typology of residential architecture, salinity associated with road maintenance in winter (Čermák et al, 2013;Ziemiańska and Suchocka, 2013), as well as the altered course of meteorological conditions under the infl uence of the "urban heat island" in relation to non-anthropogenic ecosystems (Szymanowski and Kryza, 2012;Majewski et al, 2014;Kalbarczyk et al, 2016).…”

The goal of this work was to study the temporal stability of the climate/growth relationship of 15 pedunculate oak trees in Wrocław, SW Poland. Furthermore, pointer years were defi ned and the span of their meteorological conditions was assessed. The tree-ring widths were measured with an accuracy of 0.01 mm using LINTAB TM 6 and the TSAP-Win software. The site chronology covered 128 years from 1887 to 2014. The tree rings were on average 3.56 mm wide and ranged from 2.10 to 5.43 mm. Their variation was signifi cantly infl uenced by temperature and precipitation. Tree-ring widths from 1965 to 2014 were most infl uenced (positively) by June precipitation in the year previous to the formation of the rings. From 1915 to 1964, the tree-ring widths were most strongly and negatively infl uenced by November precipitation recorded in the previous year. Ten pointer years were identifi ed, three of which were positive and seven negative. Both in the group of positive pointer years (

In this study, the growth and physiological performance of four newly bred black locust (Robinia pseudoacacia L.) clones (‘NK1’, ‘NK2’, ‘PL040’, ‘PL251’) together with one registered in Hungary (‘Üllői’) were monitored and compared in a field experiment located in the dry temperate climatic zone of Eastern Central Europe. Tree height and diameter at breast height were measured monthly during May–August 2022, an extremely dry period. Ecophysiological parameters such as leaf temperature, vapor pressure deficit, intercellular carbon dioxide level, transpiration and assimilation rates, and stomatal conductance to water and CO2 were measured in situ. There was a high clonal effect on survival rate and growth of the trees and on the physiological parameters. ‘NK1’ performed best regarding height (1.88 m), while ‘PL040’ (23.76 mm) had the highest diameter increment (n = 16–26). The highest carboxylation efficiency was found in ‘NK2’ (0.077 µmol m−2 s−1), while the lowest was in ‘NK1’ (0.035 µmol m−2 s−1), not showing a significant difference from the ‘Üllői’. Water-use efficiency values were found to be the highest in ‘NK2’ and ‘Üllői’ (4.92 and 4.78 kg m−3, respectively). Ci was found to be maximum in ‘NK1’ and ‘PL040’ (286.15 and 287.37 µmol mol−1, respectively), while it was minimum in ‘Üllői’ (248.30 µmol mol−1). Physiological parameters were found to be significantly different in the clones due to their genetic differences. A strong positive correlation was found between the transpiration and the assimilation rates (r = 0.843–0.994). Within the growing period, the loss of leaves due to abiotic stress was 0 for ‘NK1’ and negligible for the others. ‘NK2’ stood out among the other clones in most of the parameters tested (height, thickness, assimilation, WUE). In addition to its high photosynthetic intensity, its water-use efficiency was also high.
