Climatic signal in a radial growth of Canadian and Maximovich poplars in south-western Poland

Abstract

The main goal set by researchers in this article was to gather knowledge on the structure of the basic biometric features of tree-rings of two species of poplars, belonging to different sections of Aegeiros-Populus xcanadensis and Tacamahaca-Populus maximowiczii, and to define and understand the correlation between weather and annual increment. A supplementary objective of the article was to determine pointer years of species found in individual populations. Our research used the standard methodology applied in dendroclimatology. In the analysis of correlation of the tree species studied, stronger statistically significant relationships were obtained in terms of precipitation-increment compared to temperature-increment. The annual increment in the Canadian poplar was enhanced by wet autumns and winters, especially by the rainfall in Oct and Dec in the previous year, as well as in Apr of this year. The tested Maximovich's poplars tested preferred rainfall during spring going into summer, especially in June of this year. Seven specific pointer years were determined for the Canadian poplar, comprising 4 positive

Influence of growth ring number and width on elastic constants of poplar

“…Ziemiańska and Kalbarczyk (2018) reported 5.37 mm GRW for SW of the Populus x canadensis Moench, which is around 3.3 times lower than the average GRW of this study. Remarkably lower averages (6.63 mm and 8.3 mm) were also reported by Ziemiańska et al (2020), including both SW and HW. In contrast, higher means, 19.8 mm (Erten and Önal 1995), 27.8 mm (LeBlanc et al 2020), 28.6 and 28.8 mm (Šēnhofa et al 2016, and 45 to 55 mm (DeBell et al 2002), were also reported for different poplar species.…”

A Comparison of the Chronologies of Introduced versus Native Coniferous Tree Species Growing in Northwestern Poland during the Period of Global Warming

“…Under such circumstances, previously undervalued plant or animal taxa, including uncommon or introduced taxa, may gain ecological or economic significance. To monitor climate changes and their impact on forest ecosystems, the results of dendroclimatological research may be used [7][8][9][10][11][12][13][14][15][16]. Many of the introduced tree species are larger, grow faster, and have better wood value than European species [15].…”
