Abstract

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%).
