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.

Hydrological time-series are known to depict long-term structures, and pronouncednonlinearities. Singular System Analysis (SSA) is one way to extract long-term componentsof these data-sets. Classical SSA is a principal component analysis (PCA) inthe time domain...

Fungi of roots of declining pine and spruce seedlings were assessed by pure culture isolations and direct sequencing. The isolation from 1440 roots of 480 seedlings (240 per each tree species) yielded 1110 isolates which, based on mycelial morphology and ITS rDNA sequences, were found to represent 87 distinct taxa.

Resins and oils can easily evaporate during drying processes at high temperatures. The aim of this research was to investigate different drying methods such as oven-drying, vacuumdrying and freeze-drying of resin modified pine-sapwood samples to determine wood moisture content (MC) and weight percent gain (WPG). The results showed that freeze-drying is the slowest process. Vacuum drying of water impregnated samples takes approx. 7 times longer compared to oven-drying. The initial moisture content of wood before impregnation used in this research has only little influence on the WPG.

At least 60–80 Phytophthora species has been described and most of them are soil-borne pathogens causing damping off, root rot, collar and stem rot and foliar blight on different woody plant species. These microbes are sometimes difficult to isolate and even more difficult to identify. A general review of isolation, detection and some newly identified species, including Phytophthora alni complex and P. ramorum, is presented in this article.
