Norway spruce and spruce shoot aphid as indicators of traffic pollution
Environmental Pollution, 2000Two-year-old Norway spruce (Picea abies (L.) Karst) seedlings were exposed to traffic emissions along roadsides with three different traffic densities and speed limits; highway, street and a quiet local road. The responses of the exposed seedlings as a host plant and those of spruce shoot aphid (Cinara pilicornis Hartig) were studied.

Norway spruce [Picea abies (L.) Karst.] is second only to Scots pine (Pinus sylvestris) as the most important forest tree species in European forestry. It is comparatively easy to cultivate, and its wood products are very valuable for high-quality pulpwood and lumber. Its wood is broadly used in carpentry and as a construction material.

Stress Bioindicators in Norway Spruce
1992At three sites in northern Germany stress bioindicators (acid phosphatase and peroxidase activity) were determined in the needles of healthy and damaged trees. Between heathly and damaged trees at a specific site, differences in the stress bioindicators were shown, but no common pattern between the sites could be found.

Somatic Embryogenesis in Norway Spruce (Picea abies)
1995The genus Picea (family Pinaceae) consists of 36 species and about 100 subspecies and varieties. Picea is widely distributed in the northern hemisphere. Picea abies (L.) Karst, Norway spruce, is widespread in the central and northern parts of Europe and it is the most common tree in Sweden.

Flavonol glucosyltransferase from norway spruce needles
Phytochemistry, 1991Abstract A flavonol 3-O-glucosyltransferase (EC 2.4.1) was purified from Norway spruce needles. The enzyme showed the following properties: Mr of 40 000 (monomeric protein); pH optimum of 8.4 (50% activity at pHs 7.0 and 9.8); isoelectric point of pH 5.0; relative Vmax activities for isorhamnetin, quercetin and kaempferol 100:73:69 (100 = 5.3 nkat mg−

Induced Defense Responses in Norway Spruce
1996In an effort to characterize induced defense responses in Norway spruce (Picea abies), we have developed an infection system that is reproducible, do not require advanced growth systems or large space, plants for experiments is accesible all the year, and the experimental time is short.

Reliability of proof-loaded Norway spruce
Holz als Roh- und Werkstoff, 2008Strength grading of structural timber is a prerequisite for the use of timber in load-bearing constructions. The grading methods used in production today are mainly based on estimation of the modulus of elasticity (MOE) determined from measurements of either flatwise bending stiffness or resonant vibrations. By using proof-loading techniques, the yield

Photoinhibition in Situ in Norway Spruce
Journal of Plant Physiology, 1996Summary Photoinhibition, expressed as the decay of the Fv/Fm ratio during sunny days, has been found in situ in a canopy of Norway spruce ( Picea abies (L.) Karst). For the investigation of photoinhibition the chlorophyll fluorescence method was used combined with parallel continuous measurements of photosynthetically active radiation inside and ...
