Comparison of Residual Gas Characteristics in Annual Rings of Scots Pine Trees

Comparison of Residual Gas Characteristics in Annual Rings of Scots Pine Trees

In this work, we compare the chronologies of H 2 O and CO 2 , and total pressure in the vacuum-extracted annual ring disc gas samples of six Scots pine discs in a single region of tree growth; and analyze the results. It is shown that the discs have different annual CO 2 distributions, the H 2 O dat...

Zusammenfassung:In this work, we compare the chronologies of H 2 O and CO 2 , and total pressure in the vacuum-extracted annual ring disc gas samples of six Scots pine discs in a single region of tree growth; and analyze the results. It is shown that the discs have different annual CO 2 distributions, the H 2 O data weakly correlate with precipitation, but the detected cyclicity is common to all the chronologies analyzed.
