Abstract
The tree-ring analysis makes it possible to carry out a retrospective assessment of the influence of various environmental parameters on the growth and development of woody vegetation, as well as to determine their contribution to changes in radial growth in the context of the life cycle. Based on the study of tree rings, the absolute and relative dating of the layers of wood growth is made, and it is also possible to reconstruct the events occurring in a given ecosystem and having an impact on a specific tree or plantation. Various methods and tools based on computer data processing are currently used to measure the width of annual layers, which allow measurements to be carried out in a semi-automatic mode, while saving time and increasing the accuracy of measurements. The article discusses one of such methods for studying wood cores based on digitizing the pattern of tree rings and a program for positioning points, which makes it possible to exclude the use of expensive laboratory equipment, while maintaining the necessary measurement accuracy.
