en jämförelse av produktion och potentiell kvalitet hos försöksbestånd i Jämtlands län
Swedish forests are dominated by just two conifer species Norway spruce and Scotch pine. They are not able to achieve the highest possible production or fulfill industry demands for raw materials. The introduction of exotic conifers can potentially meet these shortcomings and …
är gran (Picea abies) viktig i vissa habitat?
… The interesting thing is that this "pine specialist? is also found in spruce (Picea abies) forest habitats where pine is scarce or unavailable. In many studies outside Sweden (primarily Central Europe) spruce is regularly observed in the winter diet, but I have found no reports …
Productivity of Norway spruce (Picea abies) and Scots pine (Pinus sylvestris) was studied on 12 sites in coastal areas of northern Sweden. On each site, sample plots were placed in adjacent Norway spruce and Scots pine stands with similar ages in between. Basal area, tree …
… large scale clonal propagation of Elite clonal material. For Norway spruce (Picea abies L. Karst.), SE procedures suitable for laboratory scale propagation have been available since the mid-1980s. The SE technique has a great potential for mass propagation of conifer species …
Denna studie beskriver effekterna beträffande överlevnad och tillväxt hos gran (Picea abeis L. Karst) vid tillsats av superabsorbent Luquasorb 1280R i samband med plantering under olika betingelser. Plantor i form av täckrot och barrot studerades. Tillsats av superabsorbent …
