Abstract

Potato mop-top virus (PMTV) is the type member of the genus Pomovirus. PMTV is one of the most damaging potato infecting viruses due to the symptoms induced in the tubers. The symptoms caused by PMTV can be similar to the ones induced by another potato infecting virus, Tobacco rattle virus (TRV). Both viruses are known to generate great economic losses in Norway. Since the beginning of 2005, NCRI has as one of its objectives to enhance research on PMTV and will subsequently initiate studies on TRV as well.

Abstract

Organic farming movements have traditionally aimed at a harmonious balance between animal husbandry and crop production on the farm. We bring scientific evidences that this is a prerequisite to maximize the efficiency of nitrogen use. The use of imported feed increases the total nutrient losses to the environment per litre of milk produced.

Abstract

The effect of plant age and cold hardening on resistance to pink snow mould caused by Microdochium nivale was studied in perennial ryegrass. Resistance to M. nivale was estimated as relative regrowth after inoculation and incubation under artificial snow cover at 2 degrees C. Resistance increased with increasing plant age. Cold hardened and unhardened plants of the same age displayed identical resistance. Preliminary studies indicate that expression of genes coding for the PR proteins chitinase and PR-1a increased during incubation of inoculated perennial ryegrass, but no clear difference in expression of these genes was found between plants of different ages, or in hardened versus unhardened plants.
