Abstract
The article is devoted to identification of the features of seasonal sap flow dynamics in the trees of Siberian larch (Larix sibirica Ledeb.). Trees under examine were cultivated from the Motyginsky District of the Krasnoyarsk Krai to the Pogorelsky Bor research station (56.36° N, 92.95° E) in 1970. Stem sap flow was measured in the trees during the growing seasons of 2014 and 2015. The phenological phases of development in these larches are not synchronous. The applied method and field equipment allow to get detailed data on sap flow dynamics including the beginning and end of the vegetation season.
