Norske forbrukere velger jordbær først og fremst etter smak. Nå viser ny forskning at nettopp norske lys- og temperaturforhold kan være en viktig forklaring på smaken mange forbinder med norske jordbær – kunnskap som kan bli viktig når produksjonen moderniseres.

The sensory appeal of strawberry (Fragaria × ananassa) depends on its chemical composition, including sugars, organic acids, and aroma-active volatiles. To investigate the effects of temperature and light conditions on fruit quality, strawberry plants (cv. Sonsation) were grown at six temperature regimes (9, 12, 15, 18, 21 °C, and 21/9 °C-day/night) and four combinations of light intensities (150 and 300 μmol/m2/s) and photoperiods (12 and 24 h/day). Yield, °Brix/acidity ratio and volatile compounds were assessed. °Brix increased with light intensity and photoperiod, while higher temperatures (15–21 °C) correlated with acidity. A favorable °Brix/acidity ratio correlated with both continuous light and high light intensity, as well as low ripening temperature. Volatile content peaked at 15 °C, and declined at 9 °C, proportionally elevating acids and reducing terpenoids. The findings indicate that extended high-intensity light can optimize sweetness and aroma in cv. Sonsation, whereas low temperatures benefit the °Brix-acidity balance but may reduce volatile compound development.

This report presents results from apple cultivar testing at NIBIO Ullensvang during 2016–2024. In total, 23 cultivars and advanced selections were evaluated for flowering, harvest time, yield, tree efficiency, fruit quality, and potential storage performance. Clear differences were found among cultivars in productivity and market suitability. ‘Fonn’ and ‘Jonagold Decosta Robijn’ were the most promising cultivars, combining high and stable yields, good fruit quality, and attractive fruit size. Both of them can be recommended for further commercial testing in a wide scale. Cultivar ‘Santana’ showed value as a niche cultivar because of its stable yield, scab resistance, and suitability for low-allergen and organic production, although its relatively high acidity reduced taste scores. Small fruited cultivar ‘Early Crunch’ produces very tasteful fruits and may have potential in the snack-apple segment.

Denne rapporten oppsummerer resultater fra prosjektet ‘RobustRubus’, der det ble undersøkt hvordan temperatur, daglengde og samspillet mellom disse påvirker vegetativ vekst, vekstavslutning, blomsterknoppdanning og kvile i bjørnebær. Forsøkene inkluderte både ettårige og toårige sorter under kontrollerte og naturlige klimaforhold, samt studier av sortenes kjølekrav for å bryte vinterkvile. Resultatene viser betydelige sortsforskjeller, spesielt i blomstringsrespons, kjølekrav og kviledybde. For toårige sorter er høy temperatur viktigere enn korte dager for blomsterdanning, mens klimafaktorer synes å ha mindre betydning for blomsterdanning hos ettårige sorter. Sortstesting i plasttunnel viste at flere sorter er aktuelle for norsk produksjon, med variasjon i avling, bærkvalitet og smak. Riktig sortsvalg og et tilpasset dyrkingssystem er avgjørende for å lykkes med bjørnebærproduksjon med langskudd i Norge. Rapporten gir ny kunnskap som kan bidra til en mer robust og bærekraftig produksjon, og styrking av norsk grøntsektors konkurransekraft.

Within the EUFRIN apple rootstock trials, seven apple rootstocks are being tested for their resistance to ARD (apple replant disease) in several European countries. The current paper focuses on the effects of rootstock and soil type (ARD vs. fresh soil) on the accumulation of phenolic compounds in apple fruit. This research was performed at the Lithuanian trial site. Accumulation of phenolic compounds in fruit tissues was enhanced in replanted soil. On average, total phenol content in fruit flesh increased by 25%, and in fruit peel by 31%. Hyperoside and rutin in fruit flesh, and hyperoside, reynoutrin, phloridzin, and procyanidin C1 were the most variable among detected phenolic compounds, and their content in fruits from ARD soil was by 50-77% higher than in fruits from the fresh soil. The content of (-)-epicatechin in fruit flesh and (+)-catechin and procyanidin B1 in fruit peel was similar in both ARD and fresh soil. Rootstock had a significant effect on phenolic compound accumulation, but this effect was modified by soil conditions. Soil type had no effect on total phenol accumulation in fruits (flesh and peel) grown on Pajam 2 rootstock. Also, a stable phenol content in fruit flesh was on G.11 and M200 rootstocks, and in fruit peel on G.41. The highest increase of total phenol content at replant conditions was recorded on B.10 (by 66% in flesh and 60% in peel) and on G.935 (by 68% in flesh and 47% in peel) rootstocks.

The successful introduction of new cultivars requires proper pomological, phenological, and technological evaluation. It is particularly important in the harsh Norwegian climate conditions. Investigations were conducted with apple cultivar ‘Eden’/‘Wursixo’ (WUR 6), to establish an optimal balance between yield, fruit quality, and bearing regularity. Four different crop load levels were tested in 3 consecutive years in the orchard, planted 3.5×1 m and trained as a slender spindle. Lower crop load levels guaranteed good return bloom, a very high share of fruits harvested during the first picking, and larger fruits. Increasing crop load led to less intensive return bloom, smaller fruit sizes, and a higher share of fruits harvested during the second picking. It was found that ‘Eden’ is strictly alternating cultivar and precise crop load levels according to the tree age and tree vigour were defined. In order to keep ‘Eden’ trees in regular bearing mode, crop load levels should be maintained at 4.5-5 fruits cm‑2 of trunk cross-sectional area (TCSA) in the 3rd and 6-7 fruits in the 4th growing season.
