| Outline of Final Research Achievements |
The growth limiting factors of above- and below ground part of Picea mariana, Larix sibilica and Pinus sibirica trees growing on permafrost and non-permafrost in various site in circumpolar regions were investigated. We utilized dendrochronological techniques, growth patterns of trunk, branch and root observation and stable isotope labeling techniques. The tree growth and carbon balance of forests on permafrost were mainly regulated by low temperature underground which limit the growth and functions of roots. In addition, frozen ground in spring season cause water deficit stress or flooding stress in some sites. The way of influence varies depending on climate and geological conditions as well as tree species.
