The intensity of the climatic signal in the dynamics of the inсrement of Scots pine (Pinus silvestris L.) of the Khrenovskii forest (Voronezh region, Russia)

Abstract

Our research was carried out in the center of the Voronezh Region, Russia, in the pine forest "Khrenovskoy forest", located in the forest steppe zone of the Russian Plain. The samples for dendrochronological analysis were collected from 30 trees (1 core per tree). The climatic characteristics are taken from the data of the weather stations "Khrenovskoy forest", for the period 1936-1996 and Voronezh for the period 1862-2015. In accordance with the goal of the research, we identified high correlation coefficients (up to 0.42) and dispersion (up to 0.66) between the radial increment of Scots pine and the climatic limiting growth factors (sum of atmospheric precipitation, hydrothermal coefficient Selyaninova)
