Temperate tree species show cross‐tolerance to heat, drought, and late spring‐frost stress

open access: yesNew Phytologist, Volume 251, Issue 4, Page 1625-1630, August 2026.
Significant cross‐tolerance of leaf traits to heat, drought and late spring‐frost were found. (a) Turgor loss point vs lethal spring‐frost temperature. (b) Heat thermal threshold temperature vs lethal spring‐frost temperature. (c) Heat thermal threshold temperature vs turgor loss point.

Assessing crown reduction as a strategy to mitigate drought stress during initial development of sessile oak and Norway spruce saplings

open access: yesCentral European Forestry Journal
Droughts, amplified by climate change, pose a significant threat to the success of both artificially and naturally regenerated forests. Understanding how these changes affect the initial stages of saplings development is crucial for forest establishment,

The diffusion of Norway spruce in the beechwoods of

open access: yesForest@, 2008
During the last decades, in the previously coppiced beechwoods of "Dolomiti Bellunesi" National Park, an unprecedented diffusion of Norway spruce occurred; possible silvicultural options to cope with this new condition are outlined here.

Spiral Grain in Norway Spruce

open access: yes, 2002
Wood is a major construction material that is used in many contexts, and for different purposes. Serious problems may arise, however, when moisture related deformations as twist occur in wood used in different types of building structures, joinery and furniture.

Physiology of young Norway spruce

Environmental Pollution, 1990
In the Hohenheim experiment young spruce (Picea abies L. Karst.) were exposed to low levels of SO(2) and/or O(3) and acid precipitation. At the end of a five-year experimental period (1983-88) the following physiological parameters were examined: water soluble thiols, ascorbic acid, glutathionereductase activity and pigment content.

Oligolignans in Norway spruce and Scots pine knots and Norway spruce stemwood

Holzforschung, 2004
Abstract Oligolignans present in substantial amounts in Norway spruce and Scots pine knots were characterised. The hydrophilic knotwood substances were extracted and different chromatographic methods were applied to obtain fractions for analysis by GC, GC-MS, HR-EI-MS, LC-ESI-MS, NMR, and FTIR.

Afforestation of Lutz Spruce, Sitka Spruce, and Norway Spruce in the Vesteraalen Islands, Norway

1993
Tree species from Alaska and Canada have been used for afforestation in northern Norway since the late 1920s. Afforestation projects were small in the beginning because the performance of foreign species far north of their natural range was unknown.
