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.

Abstract Two field trials are reported on Jerusalem artichoke (Helianthus tuberosus L.). Firstly, twenty genetic variants were compared with respect to crop yield, morphology and content of sugars and FOS in order to find genotypes suitable for Norwegian production. The highest yield and highest number of tubers per plant was obtained in early flowering variants, e.g. the white variant ‘Tysnes" gave 1.72 kg tubers per plant (28.7 t haa-1). Such early variants had markedly lower portion of smooth tubers. Late variants gave the most preferable tuber shape, but the yield was only half of the most productive ones. Dry matter content (%DM) varied from 19.67 to 23.33. Only a weak correlation was found between dry matter content and total content of FOS (r = 0.255) in the tubers. The mean content of FOS including sucrose through all variants was found to be 11.6 g 100g-1 FW or 55.0 g 100g-1 DW by measurement of non-hydrolyzed plant. Average chain length of FOS in the tubers was found to be DP3.9. There was no difference in tuber FOS content between flowering and non flowering variants. A second trial investigated the above ground part of one flowering and two late or non flowering variants during the growing season. Highest biomass was found for the late or non flowering variants when harvested in September. Total dry matter at time of harvest were found to be 0.21, 0.55 and 0,44 kg plant-1 for the variants ‘Dagnoytral", ‘Elverum" and ‘Krogerup" respectively (5.4, 14.1 and 11.3 t haa-1). At time of harvest stalks of ‘Elverum" and ‘Krogerup" contained 1.25 and 0.77 % fructose (DM) and 3.40 and 1.91 % sucrose. The content of soluble carbohydrates was found to be highest in stalks in August (sucrose and FOS major compounds).

The iPOPY conference on Novel Strategies for Climate Mitigation, Sustainability and Healthy Eating in Public Foodscapes was held the 25th – 26thof November, 2010 in the Copenhagen Institute of Technology arranged by the researchgroup Food, People & Design at Aalborg University. The conference attracted over 60 scientists and practitioners and focused on the difference that “outside home settings” can do in order to promote healthy eating, organic consumption and more climate friendly food choices. The conference also attracted considerable attention from news media. The report contains the conference contributions.

I 2009 vart det funne mørke flekkar på stammane på fleire spisslønn, ein bøk og ei bjørk ved Byhaugen i Stavanger. Slike flekkar er typiske symptom ved angrep av Phytophthora-artar, og vert ofte omtala som blødande sår. På dei to førstnemnde tre-artane vart det stadfesta at skadane skuldast rotråte på grunn av Phytophthora plurivora. Sjukdomen er kjent frå fleire land i Europa, der han vert sett på som ein stor trussel både i skog og andre økosystem.
