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.

Local climate conditions have a major influence on the biological decomposition of wood. To examine the influence of different temperature regimes on wood decay caused by the brown rot fungus Postia placenta in wood with differing natural durability, sapwood (sW) and heartwood (hW) of Scots pine, inoculated mini-blocks were incubated for up to 10 weeks at temperatures conducive or above optimal to wood decay. We profiled mass loss (ML) and wood composition, and accompanying changes in wood colonization and transcript level regulation of fungal candidate genes. The suppressive effect of suboptimal temperature on wood decay caused by P. placenta appeared more pronounced in Scots pine hW with increased durability than in sW with low decay resistance. The differences between sW and hW were particularly pronounced for cultures incubated at 30°C: unlike sW, hW showed no ML, poor substrate colonization and marker gene transcript level profiles indicating a starvation situation. As brown rot fungi show considerable species-specific variation in temperature optima and ability to mineralize components that contribute to wood durability, interactions between these factors will continue to shape the fungal communities associated to wood in service.

Effects of ripeness (nearly ripe, ripe, fully ripe) and cultivar (‘Blink’, ‘Polka’ and ‘Senga Sengana’) on colour and chemical composition of strawberry fruits and their suitability for jam production, evaluated as stability during storage at 4 and 20 °C for 3 and 6 months, were investigated. Quality traits of fruits and jams were significantly affected by both ripeness stage and cultivar. However, after 6 months of storage, particularly at 20 °C, the effects of fruit ripeness and cultivar were considerably reduced. During jam storage, anthocyanins, ascorbic acid, chroma and hue were least stable in jams made from the least ripe fruits. Quality traits in jams made from ‘Senga Sengana’ were best preserved during storage, while quality and chemical composition in jams made from ‘Blink’ changed the most. In conclusion, fully ripe fruits were best suited for jam processing. Storage at low temperature was preferable and ‘Senga Sengana’ was the most and ‘Blink’ the least suitable cultivar for processing.
