Abstract
Results of our investigations of gas content in rings of tree discs have shown that a significant part of CO2 generated under cell respiration remains in tree stems. Content of this CO2 exceeds the atmospheric CO2 content in most cases and forms the annual distribution over a disc. For these investigations, for the first time we use the method of laser photoacoustic gas-analysis. In this work, some features of the obtained chronologies (year-to-year distributions) of gas probes are discussed.
