Vegetative Propagation of Norway Spruce

Journal of Forestry, 1940
Abstract A study of some of the factors that control the vegetative propagation of Norway spruce indicates that this species can be conveniently reproduced by stem cuttings during the winter. A large percentage of the cuttings made in winter rooted satisfactorily and were ready to be transplanted to the outdoor nursery early in the ...

The Solling Norway Spruce site

Ecological Modelling, 1995
Abstract The Solling F1 site is a typical Norway Spruce (Picea abies) plantation forest on acid soil, with a well-developed mor humus layer, low soil biological activity and sparse ground vegetation. Inputs, outputs and internal transfers of chemical constituents have been measured continuously for more than twenty years, and were complemented by ...

Ground vegetation composition and heterogeneity in pure Norway spruce and mixed Norway spruce - birch stands

Canadian Journal of Forest Research, 1997
Les auteurs ont examine l'effet sur la vegetation au sol de l'introduction d'arbres decidus dans un peuplement pur d'epicea. L'abondance et la composition de la vegetation au sol, dans des peuplements purs d'epicea commun (Picea abies (L.) Karst.) et mixtes d'epicea commun et de bouleaux (Betula pendula Roth et Betula pubescens Ehrh.), ont ete ...

Karyotype of Norway spruce by multicolor FISH

Theoretical and Applied Genetics, 2003
The chromosomes (2n = 2 x = 24) of Norway spruce are very large since their size reflects the huge amount of genomic DNA (2C = 30 x 10(9) bp). However, the identification of homologous pairs is hampered by their high degree of similarity at the morphological level. Data so far presented in the literature were not sufficient to solve all the ambiguities

Diversity of Norway spruce needle endophytes in various mixed and pure Norway spruce stands

Mycological Research, 1998
Norway spruce needles were sampled from two series of stand areas located in southern Finland. Both series consisted of five sampling areas in mature managed stands and one in a mature virgin stand. The proportion of spruce varied from 8 to 100% of the basal tree area and the major other species were pubescent birch and Scots pine.

Norway spruce and spruce shoot aphid as indicators of traffic pollution

Environmental Pollution, 2000
Two-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.

Silviculture of Norway Spruce

2007
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

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.

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.
