Аннотация: Differences in terms of depth of dormancy have been revealed in the provenace trial of Scots pine based on an analysis of parameters of the zero fluorescence level, as well as the content of chlorophylls and abscisic acid, which corresponds to the results of studying the pine-needle morphological traits and phenological observations. Trees of the southern climatype different in terms of needle morphological traits and the length of phenological stages are characterized by a deeper dormancy than those of the northern climatype. It is assumed that, due to climate change, northern climatypes would be more vulnerable during winter-spring thaws, which were not typical of these regions in former times.
