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.

Feltinstruksen inneholder retningslinjer, definisjoner og koder for jordsmonnkartlegginga ved Skog og landskap. Sammen med dokumentene ”Norsk Referansesystem for jordsmonn” og ”Seriedefinisjoner” utgjør den det skriftlige grunnlaget for feltarbeidet. Feltinstruksen bygger på tidligere retningslinjer for jordsmonnkartlegging og revideres jevnlig i tråd med endringer av klassifikasjonssystem og rutiner.

Yield in blackcurrant is found to vary significantly between years, and fertilizer rates, methods and timing had only minor effects on this variation. Fertilization was generally most effective when applied during autumn, while fertilization in spring could be omitted or reduced without significant negative effects on the yield parameters studied. This short paper is based on results published by Opstad et al. (2007).

Lammekjøtt produsert ved grasbeite i tempererte klima er påvist å ha relativ høy andel flerumetta omega-3 fettsyre. Denne ernæringsgunstige fettsyretypen dominerer i andel hos planter og er viktig for fotosyntesen ved lave temperaturer. Ved Bioforsk Nord Holt undersøkes temperaturprofilen for fettsyrer i nordlige beiteplanter, for å undersøke om nordlig klima gir en spesielt gunstig fettsyresammensetning.

Models to simulate the fate of pesticides in the environment are frequently used for risk assessments within the registration process. Experimental data are essential for model development, for evaluating the accuracy of models in the description of field behaviour and thus for assessing the confidence that should be placed in model predictions. Various experimental techniques used at Bioforsk Plant Health and Plant Protection Division were described and a short discussion of uncertainty of experimental data given.

We present results from early tests and field trials of offspring from two Norway spruce (Picea abies (L.) Karst.) seed orchards containing clones that have been transferred from high altitudes to sea level and from northern to southern latitudes. Seedlings from seeds produced in the low-altitude seed orchard developed frost hardiness later at the end of the growth season, flushed later in field trials, and grew taller than seedlings from seeds produced in natural stands. They had the lowest mortality rate and the lowest frequency of injuries in the field trials. Similar results were observed in seedlings from seeds produced in the southern seed orchard. We found no adverse effects of the changed growth rhythm. Seedlings from two seed crops in the southern orchard, produced in years with a warm and a cold summer, had different annual growth rhythms. The results are explained mainly by the effects of the climatic conditions during the reproductive phase. Seed crops from different years in the same seed orchard may produce seedlings that perform as if they were from different provenances. It is argued that the effects of the climatic conditions during seed production must contribute to the variation among provenances of Norway spruce.
