Phenotypic and genetic studies of waterlogging tolerance in wheat and barley
(PhD Thesis;2018:50, Doctoral thesis, 2018)Stress caused by waterlogging may have considerable impact on yields of wheat, barley and other crops. As climate change projections include increased precipitation in parts of the world, one can expect an increasing demand ... -
Phenotypic and genotypic charcterization of Atlantic Salmon (Salmo salar) gut microbiota
(Master thesis, 2022)Knowledge of the Atlantic Salmon (Salmo salar) gut microbiota falls behind the research done about the human gut microbiome. Creating greater understanding of the bacteria present and their capabilities helps to create a ... -
Phenotypic and genotypic variation in the allopolyploid Arabidopsis suecica and its parent species A. thaliana and A. arenosa : an investigation of a possible model for studies of polyploidy and invasiveness
(Master thesis, 2014-09-26)Species that possess more than two sets of chromosomes are denoted as polyploids. It is hypothesized that polyploids show high gene redundancy, hybrid vigour and masking of deleterious alleles, and that this make them ... -
Phenotypic characterization and ploidy level determination of perennial ryegrass (Lolium perenne L.) gene bank accessions and cultivars
(Master thesis, 2020)Perennial ryegrass (Lolium perenne L.) is the most grown perennial grass species all over the world, because of the rapid regrowth and good nutritional composition. Winter survival is challenging when growing perennial ... -
Phenotypic effects of a fertility mutation in Norwgain White Sheep
(Master thesis, 2013-07-19)Norwegian White Sheep (NWS) is a synthetic breed that results from crosses between local Norwegian and foreign breeds. This breed is mainly kept for the meat production, and litter size is therefore a trait of large economic ... -
Phenotypic effects of knocking out the pigmentation related genes, abcg2, bco1, and bco1-like in Atlantic salmon
(Master thesis, 2022)The red muscle color is one of the main quality parameters of Atlantic salmon (Salmo salar). Unique to salmonids, the color comes from the accumulation of astaxanthin in the muscle, which is strictly obtained from the diet ... -
Photosynthesis and growth at high day temperatures in a CO2 enriched atmosphere
(PhD Thesis;2013:75, Doctoral thesis, 2013)Increasing energy prices have led to the attempt of energy saving and are one of the main research areas in greenhouse plant production. Technical disintegration has been developed, and the greenhouse concept ‘Closed/Semi-Closed ... -
Physical and social environment for sheep : effects on spacing behaviour, social interactions and activity budgets in housed ewes
(PhD Thesis;2010:49, Doctoral thesis, 2010)I innefôringsperioden blir sauen ofte holdt i et stimulusfattig miljø med høy dyretetthet og fullspaltegulv, noe som medfører begrenset tilgang til ressurser, hyppig håndtering og lite plass til å trekke seg unna eller ... -
'Pioneer Farmers' : joint exploration of crop diversity and agroecosystem function in Walsala, Nicaragua
(Master thesis, 2016-09-06)Exploring the role of crop diversity on the functioning of agroecosystems has significant implications for agriculture. ‘Pioneer farmers’, on Nicaragua’s agricultural frontier are adapting their cropping systems to new ... -
Plant-parasitic nematodes of the Ethiopian food security crop enset (Ensete ventricosum) : occurrence, distribution, characterisation and management
(PhD Thesis;2021:32, Doctoral thesis, 2021)To confront the challenges of eradicating hunger and improve food security, agricultural growth needs to be driven by intensification. This in turn increases the threat of pests and diseases, including plant-parasitic ... -
Planteutvikling og avlingsdannelse i erter (Pisum sativum L.) under norske dyrkingsforhold
(Master thesis, 2022)Bærekraftighet og miljøvennlige måter å produsere mat på er viktigere enn noensinne. Norge har en interesse av å bli mer selvforsynte på proteinvekster som råvare til bruk i proteinbaserte næringsmidler og i dyrefôr. Erter ... -

Play behaviour in preweaned Norwegian Red calves housed in different social settings
(Master thesis, 2023)The aim of this study was to describe play behaviours of calves in three different management systems during a play test using straw as a play-object. Thirty-six Norwegian Red calves were divided into two batches, with one ... -
Policies for agroforestry and diversification of productions in Wallonia
(Master thesis, 2021)Agroecology is more and more acknowledged as one of solutions toward sustainable transitions of our food systems. Practices such as agroforestry and diversification of production are part of the strategies used within an ... -
Pollen chemical composition determined by infrared spectroscopy : species identification and environmental effects.
(Master thesis, 2014-10-23)In this study pollen is collected from different populations of common and widespread plants in alpine and lowland habitats. Infrared spectroscopy was used to determine chemical composition of pollen. Although this is a ... -
Pollinator trees as a potential inoculum sources for fruit decay fungi on apple
(Master thesis, 2018)Over the recent years it has become common to plant cultivars of crab apple as pollinators at regular distance in the rows of the apple fields. Little or no specific knowledge exist about the susceptibility to diseases of ... -
