Abstract: | The distribution of frost injuries in earlywood and latewood, in different zones of stem (with respect to height, diameter, and circumference), and at the bases of large roots has been studied in Siberian spruce (Picea obovata Ledeb.) and Siberian larch (Larix sibirica Ledeb.) at the northern limit of their ranges (the Obsko-Tazovskaya forest-tundra). It has been shown that a high frequency of frost injuries, especially in spruce, is characteristic of the study region. Mass frost injuries occur only in thin trees, mainly in the lower part of stems. Guidelines for collecting and preparing wood samples for the study of frost injuries are proposed. |
