Composition of Sugars, Organic Acids, Phenolic Compounds, and Volatile Organic Compounds in Lingonberries (Vaccinium vitis-idaea L.) at Five Ripening Stages
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-05-26)Wild lingonberries are a traditional source of food in the Nordic countries and an important contributor to economic activity of non-wood forest products in the region. Lingonberries are a rich source of bioactive compounds and can be a valuable contributor to a healthy diet. However, there are few studies available on how the bioactive compounds in lingonberries develop as they ripen. In this ... -
Developmental and Environmental Regulation of Cuticular Wax Biosynthesis in Fleshy Fruits
(Journal article; Peer reviewed, 2019-04-19)The aerial parts of land plants are covered by a hydrophobic layer called cuticle that limits non-stomatal water loss and provides protection against external biotic and abiotic stresses. The cuticle is composed of polymer cutin and wax comprising a mixture of very-long-chain fatty acids and their derivatives, while also bioactive secondary metabolites such as triterpenoids are present. Fleshy ... -
A dPCR Method for Quantitative Authentication of Wild Lingonberry (Vaccinium vitis-idaea) versus Cultivated American Cranberry (V. macrocarpon)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-05-19)Berries of the genus Vaccinium are highly valued health-beneficial superfoods, which are commonly subjected to adulteration and mixed with each other, or with other common berry species. A quantitative DNA-based method utilizing a chip-based digital polymerase chain reaction (dPCR) technique was developed for identifying and quantifying wild lingonberry (V. vitis-idaea) and cultivated American ... -
Effect of organic fertilizer on growth of strawberry cultivar ‘Sonata’
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-28)Organic agriculture is acquiring increased attention in Armenia with numerous projects and initiatives prioritizing production of ecologically clean agricultural products. Application of organic fertilizers is one of the key factors supporting sustainable organic production of fruits and vegetables, which requires knowledge of fertilization regimes adapted to crop types for achieving optimum ... -
Effect of ripening temperature on the chemical composition of lingonberries (Vaccinium vitis-idaea L.) of northern and southern origin
(Journal article; Tidsskriftartikkel; Peer reviewed, 2023-03-21)Lingonberries (Vaccinium vitis-idaea L.) from two locations, northern (69◦N, 18◦E) and southern (59◦N, 10◦E) Norway, were grown under controlled conditions in a phytotron at two temperatures (9 and 15 ◦C) to study the effects of the ripening temperature and origin on the chemical composition of the berries. The concentrations of phenolic compounds, sugars, and organic acids as well as the profile ... -
Influence of Arctic light conditions on crop production and quality
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-10)The natural light conditions above the Arctic Circle are unique in terms of annual variation creating special growth conditions for crop production. These include low solar elevations, very long daily photosynthetic light periods, midnight sun/absence of dark nights, and altered spectral distribution depending on solar elevation. All these factors are known to affect the growth and the metabolism ... -
Seasonal and yearly variation of total polyphenols, total anthocyanins and ellagic acid in different clones of cloudberries (Rubus chamaemorus L.)
(Journal article; Tidsskriftartikkel; Peer reviewed, 2018-05-02)Cloudberry (Rubus chamaemorus L.) is a wild perennial shrub growing on peatland with a circumpolar distribution. The combined berries have a high polyphenol content comprised primarily of ellagitannins. A few commercial cultivars are available, and pre-breeding trials on clonal material from different geographical origins are in progress. The objective of this study was to investigate how the content ... -
Temperature has a major effect on the cuticular wax composition of bilberry (Vaccinium myrtillus L.) fruit
(Journal article; Tidsskriftartikkel; Peer reviewed, 2022-09-20)Cuticle is the first layer protecting plants against external biotic and abiotic factors and is responsive to climatic factors as well as determined by genetic adaptations. In this study, the chemical composition of bilberry fruit cuticular wax was investigated through a latitudinal gradient from Latvia (56◦N 24◦E) through Finland (65◦N 25◦E) to northern Norway (69◦N 18◦E) in two seasons 2018 ... -
Trace element concentration and stable isotope ratio analysis in blueberries and bilberries: A tool for quality and authenticity control
(Journal article; Tidsskriftartikkel; Peer reviewed, 2021-03-09)Vaccinium genus berries—wild bilberries (Vaccinium myrtillus L.) and cultivated highbush blueberries (Vaccinium corymbosum L.)—are consumed worldwide, and their consumption has a trend of stable increase. Thus, considering their wide use in ethnomedicine, for juice and jam production, as functional food, as well as their use in preparations of extracts which have application potential in pharmaceutical ... -
Økt kunnskap om økologisk tunnelproduksjon av bær. Sorter, gjødsling, dyrkingsteknikk
(Research report; Forskningsrapport, 2021-04-16)Bærproduksjon i plasttunnel har blitt trukket frem som en løsning for økologisk bærdyrking. Et slikt produksjonssystem er relativt nytt i Norge, og det er behov for mer kunnskap for å optimalisere produksjonen. I perioden 2017-2019 har vi gjennom prosjektet “Økologisk tunnelbær og flytende næring”, finansiert av Kunnskapsutviklingsmidler for økologisk produksjon i NIBIO, hatt ulike forsøk ved ...
