Fresh-stem bending of silver fir and Norway spruce.
The bending and growth characteristics of large fresh stems from four silver fir (Abies alba Mill.) and three Norway spruce (Picea abies (L.) Karst.) trees were studied. Twenty logs taken from different stem heights were subjected to four-point bending tests. From the bending test records, we calculated stress-strain curves, which accounted for detailed log taper, shear deformation and self wei...
متن کاملStorability and freezing tolerance of Douglas fir and Norway spruce seedlings grown in mid- Sweden
Climate change provides new challenges to Nordic forestry. Use of non-native species, such as Douglas fir, can be a means of mitigating the effects of climate change and meeting the growing demand for biomass. When Douglas fir is grown in Sweden, it is several degrees of latitude north of its normal range, which can affect timing of growth cessation, hardening of seedlings, and seedling storabi...
متن کاملCytokinins in Norway Spruce Seedlings and Forest Soil Pollution
KRAIGHER H. & HANKE D.E. 1996. Cytokinins in Norway spruce seedlings and forest soil pollution. Phyton (Horn, Ausrtia) 36 (3): (57) (60). Cytokinins can correlate with pollution damage in spruce trees and also with different strains and species of their mycorrhizal symbionts. In our study, Norway spruce seedlings were grown in vitro on sterilized or nonsterile soil substrates from two different...
متن کاملTemporal Stability and Dendroclimatology in Silver Fir and Red Spruce
SMITH K.T., ČUFAR K. & LEVANIČ T. 1999. Temporal stability and dendroclimatology in silver fir and red spruce. Phyton (Horn, Austria) 39 (3): (xxx) (xxx). Dendroclimatology uses precisely dated tree-ring series and climate measurements to reconstruct climate for periods prior to instrumented records. Dendroclimatology requires a predictable, relationship between growth and climate. Tree-ring se...
متن کاملSignificant Mean and Extreme Climate Sensitivity of Norway Spruce and Silver Fir at Mid-Elevation Mesic Sites in the Alps
Climate forcing is the major abiotic driver for forest ecosystem functioning and thus significantly affects the role of forests within the global carbon cycle and related ecosystem services. Annual radial increments of trees are probably the most valuable source of information to link tree growth and climate at long-term time scales, and have been used in a wide variety of investigations worldw...
