Interrelation of the Radial Increment of Trees with Various Factors

Radial increment objectively reflects the quality of assimilation apparatus a woody plant. Its features indicate influence various anthropogenic, biotic and abiotic factors as well stability plant under stress. The aim this study was to survey long-term dynamics radial growth six tree species: Betula pendula, Ulmus glabra, Quercus robur, Tilia cordata, Picea abies Pinus silvestris, depending on impact creating reservoir fluctuations water level in it. Additionally, another determine whether there is dependence between annual these species change temperature factor during growing season. We studied cores trees park coast Sheksna river, which regulated by Rybinsk Reservoir changes along with This research presents pendula over 59 years, glabra 50 robur cordata 82 128 years silvestris 125 years. average decreases series > silvestris. increase does not correlate Reservoir.
