Cloudberries (Rubus chamaemorus L.) contain several phenolic compounds, but ellagitannins and ellagic acid derivatives dominate and are primarily responsible for the antioxidative effects of cloudberry. Generally, antioxidative activities and chemical composition of berries are affected both by the genotype and the environment. The aim of this study was to investigate the role of temperature and the genotypes used in the crossings on fruit quality. Since different genotypes might respond differently to different temperatures, possible interactions between genotype and temperature were also investigated. Plants were grown under controlled temperature treatments (9, 12, 15, 18°C; variation ±0.5C) in 24-h photoperiod. Ripe berries were harvested daily, frozen individually at -100°C and stored at this temperature until chemical analyses. There was a significant effect of female parent on both total phenols and total anthocyanins in the berries. Temperature affected the level of total anthocyanins, while there was no significant effect on the level of total phenols. High through-put MS-based analyses suggested subtle differences in phenolic composition in response to temperature and genotype. The results indicate that there is a need for breeding material with a special adaptation to different climatic conditions.

Tiltaksveilederen for jordbrukspåvirka vassdrag (http://www.bioforsk.no/tiltak) er utarbeidet for å bistå i arbeidet med å gjennomføre EUs Rammedirektiv for vann (RDV) i Norge. Målgruppen omfatter derfor først og fremst fylkesmenn og kommuner, men kan selvsagt benyttes av andre interesserte. Tiltaksveilederen er finansiert av Statens Landbruks Forvaltning (SLF), som også var initiativtager til prosjektet. Den er utarbeidet av Bioforsk, samt SLF (virkemidler) og Universitet for miljø og biovitenskap, UMB (økonomi). I forbindelse med arbeidet ble det opprettet en referansegruppe bestående av representanter fra Fylkesmenn, Landbrukskontoret, Direktoratet for naturforvaltning, Statens forurensingstilsyn og Statens landbruksforvaltning. Den offisielle nettsiden for gjennomføringen av Rammedirektivet for vann (RDV) i Norge er Vannportalen. På Vannportalen er det link til Hovedveilederen for tiltak, som gir en komplett gjennomgang av alle prosedyrer, rollefordelinger og tidsfrister for gjennomføring av tiltaksplaner.

Bilberry (Vaccinium myrtillus), also called European blueberry, is one of the most significant wild berries in the Nordic countries. The berries are recognized for their bioactive properties and distinctive aroma and flavor. The effects of climate on production and the quality of bilberries have been studied in a controlled experiment in a phytotrone using clonal material. In the experiment individual plants from two Northern clones and two Southern clones of bilberry have been grown at 12◦ and 18◦ C. At each temperature 3 different light treatments have been tested; 1) 24 hour (h) natural light (long day); 2) 24 h natural light with addition of red light and 3) 12 h light (short day). All plants were kept outside during flowering to ensure pollination by insects. Berries were sampled when ripe, weighed and stored at -80◦C for later analysis of carbohydrates, acids, phenols, anthocyanins and ascorbic acid. At 12◦C the two Northern clones produced the first ripe berries 5 weeks after pollination, while the two Southern clones needed an extra two weeks to ripening. This difference was most evident at the 24 hour day length treatment. At 18◦C both the Northern and Southern clones had ripe berries from 5 weeks after pollination. The results also indicate that the Northern clones produce better at long days, with and without addition of red light, compared to the Southern clones. The levels of fructose, glucose and sucrose are higher in berries developed at 12 than 18◦ C (means of all treatments and all clones). Also the level of citric acid, quinic acid, myo-inositol, gallic acid, cathecin, epigallocatechin, catechin derivates and quercetin are higher at the lowest temperature.

Plant polyphenolics continue to be the focus of attention with regard to their putative impact on human health. An increasing and ageing human population means that the focus on nutrition and nutritional enhancement or optimization of our foodstuffs is paramount. Using raspberry as a model we have shown how modern metabolic profiling approaches can be used to identify the changes in the level of beneficial polyphenolics in fruit breeding segregating populations and how the level of these components are determined by genetic and/or environmental control. Interestingly the Vitamin C content appeared to be significantly influenced by environment (growth conditions) whilst the content of the polyphenols such as cyanidin, pelargonidin and quercetin glycosides appeared to much more tightly regulated suggesting a rigorous genetic control. Preliminary metabolic profiling showed that the fruit polyphenolic profiles divided into two gross groups segregating on the basis of relative levels of cyaniding-3-sophoroside and cyaniding-3-rutinoside, compounds implicated as conferring human health benefits.

Hykor raisvingel kan nyttast som rein sort eller i blanding med andre sortar. Unntaket er timotei som vil gå fort ut i lag med Hykor. Sorten overvintrar godt og startar veksten tidleg om våren. Førsteslåtten har få aks som skyt tidleg og den raske gjenveksten er kun blad. Stor avling og tidleg slått gjer at det ikkje bør gå meir enn 5-6 veker mellom slåttane, både for å utnytta det store gjenvekstpotensialet og for å oppnå ein akseptabel fôrkvalitet.
