Publikasjoner
NIBIOs ansatte publiserer flere hundre vitenskapelige artikler og forskningsrapporter hvert år. Her finner du referanser og lenker til publikasjoner og andre forsknings- og formidlingsaktiviteter. Samlingen oppdateres løpende med både nytt og historisk materiale. For mer informasjon om NIBIOs publikasjoner, besøk NIBIOs bibliotek.

For non-native tree species with an origin outside of Europe a detailed compilation of enemy species including the severity of their attack is lacking up to now. We collected information on native and non-native species attacking non-native trees, i.e. type, extent and time of first observation of damage for 23 important non-native trees in 27 European countries. Our database includes about 2300 synthesised attack records (synthesised per biotic threat, tree and country) from over 800 species. Insects (49%) and fungi (45%) are the main observed biotic threats, but also arachnids, bacteria including phytoplasmas, mammals, nematodes, plants and viruses have been recorded. This information will be valuable to identify patterns and drivers of attacks, and trees with a lower current health risk to be considered for planting. In addition, our database will provide a baseline to which future impacts on non-native tree species could be compared with and thus will allow to analyse temporal trends of impacts.

Rapporten omhandler arbeid som NIBIO har utført på oppdrag fra Mattilsynet vedrørende et overvåking og kartleggingsprogram for Phytophthora ramorum. Rapporten omtaler også resultat av Mattilsynets tilsynsprøver i planteskoler og prøver tatt ut av NIBIO i samarbeid med Mattilsynet i lerkplantasjer....

Secured supply of apple fruit for industrial use, especially for production of cider was investigated. The research questions were; is it more land to be used for apple growing in the Hardanger region?, is it possible to develop an own growing concept for fruit for industrial use?, how is the economy in an own concept? And what quality demands for the raw material is needed? More land is available in the region and how much is dependent on which quality the producers demand. The input factors in a growing concept were evaluated for economically impact and price level for the different classes were the most important. Fruit of different origin (discarded at picking or at grading) were compared. Yield level was most likely the most important factor for the differences found. Prognose of amount available for industry was calculated based on models from other countries and found to have potential. Knowledge gaps were identified, and further work is needed to determine quality demands.
