Variability in the Water Footprint of Arable Crop Production across European Regions
(Journal article; Peer reviewed, 2017-02-08)Crop growth and yield are affected by water use during the season: the green water footprint (WF) accounts for rain water, the blue WF for irrigation and the grey WF for diluting agri-chemicals. We calibrated crop yield ... -
Variability of Major Phenyletanes and Phenylpropanoids in 16-Year-Old Rhodiola rosea L. Clones in Norway
(Peer reviewed; Journal article, 2020-07-30)Rhodiola rosea L. (roseroot) is an adaptogen plant belonging to the Crassulaceae family. The broad spectrum of biological activity of R. rosea is attributed to its major phenyletanes and phenylpropanoids: rosavin, salidroside, ... -
Variation in gluten quality parameters of spring wheat varieties of different origin grown in contrasting environments
(Journal article; Peer reviewed, 2015-02-15)The aim of this study was to investigate variation in protein content and gluten viscoelastic properties in wheat genotypes grown in two mega-environments of contrasting climates: the southeast of Norway and Minnesota, ... -
Variation in rate of phenological development and morphology between red clover varieties: Implications for clover proportion and feed quality in mixed swards
(Journal article; Peer reviewed, 2019-05-28)Red clover (Trifolium pratense) grown in mixtures with grasses often constitutes a lower proportion of total yield in spring than in summer growth. A more even red clover proportion between the harvests would benefit forage ... -
Variations in biomass of fungal guilds are primarily driven by factors related to soil conditions in Mediterranean Pinus pinaster forests
(Peer reviewed; Journal article, 2022-01-30)Soil fungi are vital for regulating ecosystem carbon balance and productivity, by driving processes related to soil carbon and nutrient cycling. The rate and capacity of fungi-mediated processes are linked to fungal biomass ... -
Variations in nitrogen utilisation on conventional and organic dairy farms in Norway
(Journal article; Peer reviewed, 2017-06-22)Reduced N-surpluses in dairy farming is a strategy to reduce the environmental pollution from this production. This study was designed to analyse the important variables influencing nitrogen (N) surplus per hectare and per ... -
Variations in polyphenol and heavy metal contents of wild-harvested and cultivated seaweed bulk biomass: Health risk assessment and implication for food applications
(Journal article; Peer reviewed, 2018-07-27)Seaweeds are increasingly used in European cuisines due to their nutritional value. Many algal constituents, such as polyphenols, are important antioxidants and thus considered beneficial to humans. However, many seaweed ... -
Variations of energy intensities and potential for improvements in energy utilisation on conventional and organic Norwegian dairy farms
(Journal article; Peer reviewed, 2017-06-17)abstract Due to the limited resources of fossil fuels and the need to mitigate climate change, energy utilisation for all human activity has to be improved. The objective of this study was to analyse the correlation between ... -
Varied diets, including broadleaved forage, are important for a large herbivore species inhabiting highly modified landscapes
(Peer reviewed; Journal article, 2020-02-05)Diet quality is an important determinant of animal survival and reproduction, and can be described as the combination of different food items ingested, and their nutritional composition. For large herbivores, human landscape ... -
Vegetables and social relations in Norway and the Netherlands: A comparative analysis of urban allotment gardeners
(Journal article; Peer reviewed, 2018-03-01)This article aims to explore differences in motivation for and actual use of allotment gardens. Results from questionnaire surveys and semistructured interviews in two Norwegian and one Dutch garden show that growing ... -
Vegetation modulates the impact of climate extremes on gross primary production
(Peer reviewed; Journal article, 2021-01-05)Drought and heat events affect the uptake and sequestration of carbon in terrestrial ecosystems. Factors such as the duration, timing, and intensity of extreme events influence the magnitude of impacts on ecosystem processes ... -
Vernalization Requirement and the Chromosomal VRN1-Region can Affect Freezing Tolerance and Expression of Cold-Regulated Genes in Festuca pratensis
(Journal article; Peer reviewed, 2016-02-25)Plants adapted to cold winters go through annual cycles of gain followed by loss of freezing tolerance (cold acclimation and deacclimation). Warm spells during winter and early spring can cause deacclimation, and if ... -
Vertically divergent responses of SOC decomposition to soil moisture in a changing climate
(Peer reviewed; Journal article, 2022-01-09)The role of soil moisture for organic matter decomposition rates remains poorly understood and underrepresented in Earth System Models (ESMs). We apply the Dual Arrhenius Michaelis-Menten (DAMM) model to a selection of ESM ... -
Viability of Embryo Sacs and Fruit Set in Different Plum (Prunus domestica L.) Cultivars Grown under Norwegian Climatic Conditions
(Peer reviewed; Journal article, 2022-01-14)Compatibility and synchrony between specialized tissues of the pistil, female gametophytes and male gametophytes, are necessary for successful pollination, fertilization, and fruit set in angiosperms. The aim of the present ... -
Vitality and in vitro pollen germination of different ‘Oblačinska’ sour cherry clones
(Journal article; Peer reviewed, 2017)Vitality of pollen, in vitro pollen germination and pollen tube growth (pollen tube length and pollen tube growth rate) were investigated in Oblačinska sour cherry in order to determine the differences between clones which ... -
Volatile Organic Compound Profiles From Wheat Diseases Are Pathogen-Specific and Can Be Exploited for Disease Classification
(Peer reviewed; Journal article, 2022-01-07)Plants and fungi emit volatile organic compounds (VOCs) that are either constitutively produced or are produced in response to changes in their physico-chemical status. We hypothesized that these chemical signals could be ... -
Vulnerability and resilience of the carbon exchange of a subarctic peatland to an extreme winter event
(Journal article; Peer reviewed, 2018-06-01)Extreme winter events that damage vegetation are considered an important climatic cause of arctic browning—a reversal of the greening trend of the region—and possibly reduce the carbon uptake of northern ecosystems. ... -
