Flavonol glucosyltransferase from norway spruce needles

Phytochemistry, 1991
Abstract 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

1996
In 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, 2008
Strength 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, 1996
Summary 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 ...

Norway Spruce (Picea abies (L.) H.Karst.)

2013
Norway spruce (Picea abies (L.) Karst.) is one of the most important coniferous species in Europe both from an economic and ecological point of view. Solid wood products and pulp and paper products have the largest economic value. The patterns of variation observed in Norway spruce provenance trials show geographic variability on a large scale. Genetic

Norway Spruce Picea abies (L.) Karst

2018
The increasing use of wood as a source of bioenergy, bio-products and conservation of more natural (old) forests with high biodiversity, compel us to find means to increase forest productivity. Using the best quality regeneration material can increase the economic gain obtained from future silvicultured forests.

Norway Spruce Function in Polluted Environments

2007
The economic importance of Norway spruce (Picea abies) is a key reason why this species has been the subject of numerous studies of the impacts of toxic pollutants on forest trees (Bennett and Buchen 1995). Experiments with Norway spruce are also justified owing to a large intraspecific variation in tolerance to environmental pollutants.
