• Variation of wood density of Norway spruce in Baden-Württemberg under different site conditions and climate. Statistical analysis and models of wood density
  Description of the project:

  Dendroclimatic studies have shown that wood density is highly sensitive to climate variations at the inter-annual time scale. However, inter-annual studies to date have mainly considered only minima and maxima wood density values or values averaged over parts of early- and latewood and entire annual rings, respectively. Little information is provided so far on the effects of climate on wood formation at the tree-ring scale. The hypothesis that variations in climate are reflected in the intra-annual density pattern and not solely in averaged or extrema density values will be investigated in this project. The intra-annual variation of wood density of Norway spruce of six different Level II-plots in Baden-Württemberg will be studied. Significant variations of wood density may be due to specific growth conditions and may contain information on influence of external factors such as climate on wood formation. The detailed analyses will increase our understanding of the relation between the environmental conditions and the density profil and will enable us to built more reliable models to predict wood density in Norway spruce.
