White сedar growth in the N.V. Tsitsin Main Botanical Garden arboretum of Russian Academy Of Sciences according to dendrochronological analysis

The study materials of the White сedar (Thuja occidentalis L.) radial growth (the width of the annual ring) variability in the N.V. Tsitsin Main Botanical Garden arboretum of the Russian Academy of Sciences are presented. The main patterns of short-term and long-term variability of radial growth are established, the influence peculiarities of meteorological parameters on the growth figures are revealed, a yield table of tree growth by trunk diameter is compiled. Based on the results of dendroclimatic analysis, recommendations for the care of plants are given. The results of dendroclimatic analysis were compared with the results of similar studies of White Cedar growth in the Mytishchi branch of the Bauman Moscow State Technical University arboretum.
