Sensitivity of the Structural Characteristics of Tree Rings to Climatic Changes in Different Climatypes of Scotch Pine

Radial increment and tree-ring structure were studied in the progenies of 16 climatypes growing in the southern taiga subzone. The coefficients of correlation between tree-ring parameters of the local and other climatypes were as high as 0.7-0.9, and the synchronism coefficients were higher than 0.7...

Description
Summary:Radial increment and tree-ring structure were studied in the progenies of 16 climatypes growing in the southern taiga subzone. The coefficients of correlation between tree-ring parameters of the local and other climatypes were as high as 0.7-0.9, and the synchronism coefficients were higher than 0.7. Climatypes of northern origin were an exception. The sensitivity of the parameters of the tree-ring late wood decreased with an increase in the latitude at which the seeds for establishing the cultures were collected. Estimation of Euclidean distances in the space of tree-ring parameters showed that the northern climatypes differed from the southern taiga types by no more than 15%. The climatypes from the middle taiga and the forest-steppe exhibited smaller differences (10-11%).[PUBLICATION ABSTRACT]
