Summary: For the first time, tree-ring chronologies of aspen (Populus tremula L.) from different regions of the Russian Plain were compiled: Moscow and the Moscow Region, Kaluga Region, Tver Region, the Republic of Mordovia. Сluster analysis of the chronology similarity, correlation analysis of similarity was performed, as well as the technology of identifying the geographical origin of wood previously developed by scientists of the Moscow State University of Forest was tested. The established patterns can form the basis for the formation of a system of voluntary certification of the legality of wood harvesting using cluster methods of analysis of dendrological chronologies. The main algorithm for identifying the place of origin of wood can be taking into account the correlation coefficient of local sites of indexing chronologies. By itself, the value of this indicator can be any, but in the sample of such values, the maximum will characterize wood samples that have a single group affiliation. This technology has previously been widely tested in identifying the place of origin of pine and spruce. In this study, it is confirmed by the material of the chronologies of aspen and thus we can say that it is quite general and has broad prospects. © Petrozavodsk State University |
