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.

The paper analyses and discusses possible impacts on Norwegian agriculture of an EU membership based on the regionalized agricultural sector model CAPRI. Norwegian agriculture is characterized by a small-scale farming structure and high levels of support. Previous analyses have shown that Norwegian agriculture is expected to undergo dramatic changes because of EU membership in terms of farm income, production and structural change. Our study indicates that a substantial share of the agricultural production can be maintained at the national level. Milk and crop production may remain largely unaffected, while meat production decreases in the range of 10–20% compared to a reference run without membership. However, a reduction in total farm income by about 40% indicates that structural adjustments will follow EU accession. The results are discussed in view of the pattern of adjustments observed in Finland and Austria after EU accession in 1995. The need for the dairy industry to take advantage of the improved market access is stressed. Attention is also called to some strengths and limitations of the CAPRI model to analyse large-scale policy changes and to identify model improvements as an area of future research.
