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 vert her rapportert frå forsøk med lagring av eple av sorten Aroma i kontrollert atmosfære ved ulike temperaturar og oksygennivå. Det var dårlegare fruktkvalitet og meir alderssamanbrot i eple lagra i vanleg luft samanlikna med lågt oksygennivå. Mengd bitterrote (den mest vanlege lagersjukdomen i forsøka) var også noko påverka av oksygennivået, men resultata her var ikkje heilt eintydige.

Growth, death and N dynamics of leaves, stolons and roots of harvested and unharvested white clover (cv.""Snowy"") were studied in a pot (Sturite et al., 2006) and a combined plot and root window experiment in southeast Norway (Sturite et al., 2007). Leaves of undisturbed plants contained 1.5 g N pot-1 or 6 g N m-2 in late autumn (roughly assuming 4 plants m-2). About 60% of the leaves turned over within the growing season. Thus, in an established, undisturbed white clover stand, leaf turnover would contribute 9 g N m-2 during the growing season. For stolon and root segments tagged during the first growing season, 100% and 91%, respectively, were still present in late autumn. By the end of the second growing season, the corresponding values were 77% and 46%. Thus, dead stolons and roots contributed substantially more to N deposition in the soil in the second than in the first growing season. If taking the turnover of all plant organs into account, the gross N input to the soil-plant system during the two growing seasons would amount to 63 g N m-2. This corresponded to a 2.5-fold increase over the total N in the shoots harvested during the same period.

Modellsimuleringar med utgangspunkt i vêrdata for Sola, Gardermoen, Værnes og Tromsø gir ikkje sikre haldepunkt for at klimaendringar har gitt grunnlag for tidlegare førsteslått. Det var berre på Gardermoen at begynnande skyting hos timoteien har komme stadig tidlegare gjennom førtiårsperioden.

Norwegian onion growers have in recent years complained about bacteria like disease problems of bulb onion, Allium cepa L., both in the field and in storage.  In order to find out which bacteria that are involved in theses rotting symptoms, a small survey was carried out on diseased onions from different parts of the country. Biochemical- and pathogenicity tests and fatty acid profiling showed that there was a lot of different bacteria present in the diseased onions. Many of them were ordinary water- and soil residents, which are not known to cause diseases of onion, such as Enterococcus, Salmonella, Cedecea, Stenotrophomonas, Chryseobacteruim and Curtobacterium. But there were also bacteria present which are known to cause diseases of onion in other countries, such as Burkholderia gladioli pv alliicola, Pseudomonas viridiflava, Enterobacter chloacae and Pantoea agglomerans. This is the first report of Burkholderia gladioli pv alliicola in Norway.
