| Zusammenfassung |
| Tree ring width, density and ratio of stable isotopes (13C/12C and 18O/16O) in wood and
cellulose were determined for larch (Larix sibirica Ledeb.) growing under water deficit
conditions in the forest-steppe zone in Central Siberia. Dendroclimatic analysis of the
chronologies indicated precipitation to be the most important factor determining tree-ring
structure. Precipitation of June is significantly correlated with tree ring width (TRW) and
maximum density (MXD) (r=0.36 and 0.43, p |
