Abstract: | An analysis was performed of the climatic responses of the radial growth of Larix gmelinii (Rupr.) Rupr. at two sites—both of which included contrasting north- and south-facing slopes—in Tura, central Siberia, with
the development of ring width and maximum-density chronologies for each slope. Both residual and standard chronologies of
ring widths were positively correlated with temperature from late May until mid June on all four slopes. By contrast, standard
chronologies of ring widths were negatively correlated with precipitation during the winter (from October to April) and in
May on the north-facing slope at site 1 and on the south-facing slope at site 2 respectively. The negative correlations with
precipitation during the winter and in May on some of the slopes suggested that delayed snowmelt in early spring might inhibit
the radial growth of L. gmelinii, and the effects of snow are likely to vary with topography. Both residual and standard chronologies of maximum densities
were positively correlated with temperature in early July on all four slopes. Maximum densities were also positively correlated
with precipitation during summer of the previous year on all the slopes. These suggest that no major differences exist in
terms of responses of maximum density to climatic factors between the north- and south-facing slopes. |
