Contribution of Xylem Anatomy to Tree-Ring Width of Larch in Permafrost and Non-Permafrost Zone of Siberia
Due to adaptation plasticity to climate conditions, some tree species are widespread. How can mechanisms for adapting to contrasting environmental conditions change the patterns of tree rings formation? In this study, we explored differences in climatic conditions of permafrost and non-permafrost zo...

Due to adaptation plasticity to climate conditions, some tree species are widespread. How can mechanisms for adapting to contrasting environmental conditions change the patterns of tree rings formation? In this study, we explored differences in climatic conditions of permafrost and non-permafrost zones to estimate their influence on radial growth of Larix sibirica L. and Larix gmelinii Rupr (Rupr). We quantified the contribution of xylem cell anatomy to the tree-ring width variability. Comparison of the anatomical tree-ring parameters over the period 1963–2011 shows significant differences ( p < 10 −3 ) in the most characteristics of tree-ring structure between habitats based on non-parametric Mann-Whitney U test. Permafrost zone corresponds to lower cell production (30% difference in absolute average values between sites), smaller lumen diameter (10% difference) and thicker cell wall (50% difference). However, no difference was detected in cell-wall thickness of latewood ( p > 0.05). The generalized linear modeling shows the common dependence between tree-ring width (TRW) and the cell structure characteristics in contrasting environments, which can be defined as non-specific to external conditions.
