Stress Bioindicators in Norway Spruce

1992
At 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.

On the formation of lignin polysaccharide networks in Norway spruce

Phytochemistry, 2015
In this study we were mirroring suggested in vivo phenomena of lignin-hemicellulose complex formation in vitro, by cross-linking Norway spruce (Picea abies) galactoglucomannans, xylans and lignin moieties to high molecular weight complexes by laccase treatment.

Somatic Embryogenesis in Norway Spruce (Picea abies)

1995
The 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.

Regulation of Somatic Embryo Development in Norway Spruce

2020
Somatic embryogenesis in Norway spruce combined with reverse genetics can be used as a model to study the regulation of embryo development in conifers. The somatic embryo system includes a sequence of developmental stages, which are similar in morphology to their zygotic counterparts. The system can be sufficiently synchronized to enable the collection

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 ...

Structure of lignins in developing xylem of Norway spruce

Plant Physiology and Biochemistry, 2006
The developing xylem in a Norway spruce (Picea abies) clone was investigated during a growth season and compared to lignin from sapwood of the same tree clone. Klason and acid-soluble lignin contents were determined as well as the carbohydrate monomer distribution and protein content.
