Due to a late harvesting season compared to that found in other European countries, the sweet cherry industry in Norway is now expanding, aiming for export markets. Cultivars producing high quality fruit that ripen late (late July and throughout August) and that are suitable to grow in high density production systems are sought. In addition, early ripening cultivars are sought for local marketing in early and middle July. Testing cultivars and advanced selections has been carried out at Ullensvang Research Centre since 1959. During the last decade, 130 cultivars and advanced selections have been included in the testing program. Important parameters like fruit size, fruit firmness, low fruit cracking, high and precocious yield, fresh appearance and good flavour have been evaluated. Based on the results from this testing program, the following cultivars are currently recommended: a) for early season: `Burlat", `Moreau" and `Merchant", b) for mid-season: `Giorgia", `Chelan", `Samba", `Techlovan" and `Van", c) for late season: `Lapins", `Kordia", `Regina" and `Sweetheart".

Some high density sweet cherry orchards in Norway suffer from decay of trees resulting in death or reduced vigour of trees. A survey monitoring healthy and infected trees from several orchards found differences between cultivars and rootstocks in sensitivity of tree decay. In order to investigate this cherry tree decay further, new field trials were established in 2002 with trees of the cultivar Van grafted on the two rootstocks Prunus avium seedling and Colt and trained as central leader trees. Two parallel trials were planted; one in the soil of an old cherry orchard and the other in the soil from agricultural land where no fruit production had been conducted in advance. During the first years significant larger annual vegetative growth measured as trunk girth, annual shoot growth and leaf areas were registered from the trees growing in the virgin soil. In the replanted cherry soil, trees grafted on the rootstock Colt grew more vigorously than the seedling rootstock based on leaf areas and shoot growth measurements. The rootstock Colt may be the answer for avoiding cherry replant diseases.

‘The Symposium on Climate Change and Variability – Agro Meteorological Monitoring and Coping Strategies for Agriculture’ is organized by the Management Committee of COST734’ Impact of Climate Change and Variability on European Agriculture’ and the Commission for Agricultural Meteorology (CAgM) of WMO. The content of the symposium is closely connected to the themes of the working groups of COST734 and the term of reference of the ‘WMO Expert Team on Climate Risks in Vulnerable Areas” The symposium is devoted to the very important issue of agricultural crop production and climate change. The discussion is placed in the light of agro meteorology, in Europe and in the rest of the world. The event will serve as a meeting place between meteorologists and agronomists. The cooperation between these two groups of researchers is important to find optimal mitigation and adaptation strategies with respect to impacts of climate change/variability on agriculture. The book of abstracts for the symposium contains altogether 52 contributions. 26 of the abstracts are oral contributions, and 26 of the abstracts will be presented as posters.

An infectious cDNA clone of a Norwegian isolate of Poinsettia mosaic virus (PnMV) was generated. It consisted of 6,098 nucleotides and encoded a polyprotein of 219.5 kDa. Sequence comparisons indicated that this isolate shared 98.6% (nucleotide) and 97.1% (amino acid) identity with the previously sequenced isolate from Germany. RNA transcripts derived from this cDNA were infectious in Nicotiana benthamiana. However, plants did not present typical PnMV symptoms. Furthermore, RNA transcripts from this cDNA clone were not infectious in poinsettia. Serial propagation of this cDNA clone in N. benthamiana plants restored symptom induction in this host but did not re-establish infectivity in poinsettia.

Under de tørre og vanskelige forholda våren 2008 fikk vi bedre mindre ugras og bedre etablering av sauesvingelen ved ei forsiktig behandling av det falske såbedet med med "crossboard" før såing. Såing med Stokkland såmaskin med frøapparat og slepelabb gav bedre oppspiring enn såing med Underhaugs direktesåmaskin eller Väderstad Rapid direktesåmaskin. Fjellrapp (Poa alpina) spirte raskere enn smyle (Avenella flexuosa) og tålet derfor tidligere sprøyting med ugrasmidlet Hussar (jodsukfuron).

Det er nå mulig å søke etter artikler i Norsk frøavlsnytt på internett. Søkefeltet finner du på frøavlssida til Bioforsk Landvik med adressen: http://www.bioforsk.no/froavl. Dette er samme side hvor du også finner oppdaterte dyrkingsveiledninger til alle gras- og kløverarter som frøavles i Norge. Både dyrkingsveiledningene og artiklene i Norsk frøavlsnytt er lagt ut i PDF-format. I databasen kan du til sammen søke etter om lag 400 artikler i fra perioden 1996 og fram til i dag. Du kan for eksempel søke etter aktuelle artikler ved å skrive inn emneord som gjødsling, etablering, ugras, sopp, vekstregulering, økonomi, økologisk etc i søkefeltet, og gjerne kombinere søket med engvekst eller forfatter, årstall etc. En søkekombinasjon kan for eksempel være: ugras timotei.

Bortsett frå litt mjøldogg, er søtmispel (Amelanchier spp.) som regel svært friske planter både som hekk og frittståande buskar, men i 2007 vart det observert sølvglanssopp (Chondrostereum purpureum) på eldre planter i ein hekk på Ås. I tillegg var det mykje raud vortesopp (Nectria cinnabarina).
