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.

  Det ble gjort gjødslingsforsøk i tre felt (Innvik i Stryn, Saltermark i Brønnøysund, Alvestad i Harstad) i 2009. Det er brukt fastgjødsel [AgromarinTM (Agromarin AS), Marihøne Pluss (Norsk Naturgjødsel AS)] og flytende gjødsel [OaseTM 8-2-10 (Nordisk Miljøteknologi AS)]. Dyrking av økologiske bringebær i tunnel har gitt gode avlinger også i ugunstige klimasoner. I prosjektet er det gjort en rekke klimaregistreringer

Phytophthora cactorum causes crown rot in strawberry (Fragaria x ananassa Dutch.), which is characterized by wilting and eventually collapse of the plant. An efficient control measure is the use of resistant cultivars, however most commercial cultivars are susceptible to the disease. The aim of our work is to generate basic knowledge about P. cactorum resistance as well as to develop genetic markers that can be used as tools for development of resistant cultivars. The genetic complexity of the octoploid cultivated strawberry, has led to development of the diploid wild strawberry (F. vesca) as a model system for Fragaria. We have identified suitable parents after screening accessions of diploid Fragaria sp. for resistance [1], and generated a mapping population which we are currently characterizing. In order to study the plant-pathogen interaction in detail we have identified and characterized resistance genes from diploid strawberry and effector genes from P. cactorum using different transcriptional analysis techniques; nucleotide-binding site (NBS)-profiling for resistance genes, and suppression subtractive hybridization (SSH) as well as a designed effector-specific differential display (ESDD) for genes involved in pathogenicity.   This work is supported by The Research Council of Norway.   [1] Eikemo H, Brurberg MB, Davik J (2010).

Smak og ulike kvalitetsdimensjoner hos grønnsaker påvirkes av flere abiotiske vekstfaktorer som lys og temperatur. Disse vekstbetingelsene er særegne i nord på grunn av forholdsvis lave dyrkningstemperaturer og lange dager. I dette prosjektet sees det nærmere på ulike helsegode innholdsstoffer i tillegg til smak i brokkoli for å dokumentere den nordlige kvaliteten.

At present the development of a modern life-stile in the Barents region has become not only a medical, but a social and economic problem as well. To prevent organism from unfavorable factors of the North and life-stile diseases much attention is paid now to the application of adaptogenic plants. "Herbs in the Barents region - a natural resource that improves health and creates business" is a title of the joint project of Norwegian, Finnish and Russian scientists on the adaptogenic plants. The project main goal is to create job opportunities in the Barents region based on the natural resources of adaptogenic herbs. This shall be done by the development of cultivation techniques for the adaptogenic pants Rhodiola rosea, Rhaponticum carthamolides and Serratula coronata. The industry will develop new herb products that will improve health conditions in the region. In order to promote adaptogenic products made from local plant raw material we have investigated the effect of the climate and geographical location on the level of active substances. Gene banks of plant species studied are established in all countries-participants. Experiments conducted in phytotrone showed that all three plant species like long days (northern conditions) and the levels of adaptogen"s substances are highest at the low and intermediate temperatures. Cultivation techniques are developed. To ensure the best quality of the raw material the methods of harvesting, drying and storing of plants are optimized.  New methods for extraction from fresh raw material of R. rosea are developed. Fields at growers are established. The project was financing by Interreg IIIA, Norwegian Barents Secretary and agricultural offices of the counties Troms and Finnmark.

Målet med gjødslinga i potet er å oppnå et høyt avlingsnivå og riktig kvalitet til potetene. Gjødselpraksisen må være til minst mulig belastning på miljøet. Dette må ikke gå på bekostning av kvalitetskravene de ulike produksjoner har. En nøye gjennomtenkt gjødselplan er det beste verktøyet for å oppnå dette.
