Karyotype of Norway spruce by multicolor FISH
Theoretical and Applied Genetics, 2003The 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

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.

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 ...

Diversity of Norway spruce needle endophytes in various mixed and pure Norway spruce stands
Mycological Research, 1998Norway 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.

The oldest fossil remains of spruce are described under the name Picea protopicea, and originate in the upper Cretaceous epoch. Additional fossil specimens of spruce occur in the sediments of the Tertiary (P. engleri in Paleogenian Baltic amber), and particularly the later Neogene, spanning the Miocene and Pliocene.

Distortion of Norway spruce timber
Holz als Roh- und Werkstoff, 2001This paper clarifies the extent to which models based on two- and three-dimensional material descriptions can predict bow and spring deformation. Changes in longitudinal shrinkage and swelling and their variations over cross-sections of studs cause these studs to develop distortion in terms of spring and/or bow.

Vegetative Propagation of Norway Spruce
Journal of Forestry, 1940Abstract 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 ...

Cytology of Norway spruce needles
European Journal of Forest Pathology, 1987AbstractThe structural changes in the albuminous, endodermal and mesophyll cells in the ageing needles of different aged healthy spruces (Picea abies [L.] Karst.) were studied on material collected in Germany and in Finland in winter. The results are considered as background information for the studies dealing with the structural changes in spruces ...

The Solling Norway Spruce site
Ecological Modelling, 1995Abstract 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 ...

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.
