Effects of culture conditions on the photoautotrophic growth and biochemical composition of Chlamydomonas reinhardtii, as a potential source for hydrogen production
(PhD Thesis;2014:85, Doctoral thesis, 2014)Hydrogen is a particularly attractive energy carrier, since its combustion produces water vapor only. The green microalga Chlamydomonas reinhardtii is able to produce hydrogen under sulfur-deficient anaerobic conditions ... -
Effects of storage time, temperature and modified atmosphere on sensory quality and health related compounds in fresh-cut swede and turnip
(PhD Thesis;2015:9, Doctoral thesis, 2017-07-06)Introducing new fresh-cut vegetable products onto the market may increase vegetable consumption. Usually the availability of Norwegian grown vegetables for fresh-cut production is limited by a short growing season. However, ... -
Evolution of adaptations to temperate climate in the grass subfamily Pooideae
(PhD Thesis;2016:89, Doctoral thesis, 2016)Temperate biomes are characterized by strong temperature and photoperiod seasonality and frequently occurring frost. Temperate plants have evolved to overcome challenges like cold stress, prolonged winters and short ... -
Fungicide resistance and resistance dynamics in Botrytis populations in Norway
(PhD Thesis;2022:6, Doctoral thesis, 2022)Grey mould, caused by Botrytis spp., causes serious losses in agriculturally and economically important crops worldwide. Growers in Norway have experienced grey mould control problems, and fungicide resistance in the ... -
Fusarium infection and its effects on germination and deoxynivalenol content of oats and screening for resistance by VIS-NIR spectroscopic methods
(PhD Thesis;2014:78, Doctoral thesis, 2014)Fusarium head blight (FHB) causes a great concern in Norway, and in the world at large, due to the mycotoxins produced by the causative pathogens. Different cultural practices, including deployment of resistant cultivars, ... -
Fusarium verticillioides and fumonisin management in maize in Ethiopia
(PhD Thesis;2016:18, Doctoral thesis, 2017-07-11)Fusarium species are major threats to maize production worldwide, including in Ethiopia. Little has been known about the species composition and prevalence of Fusarium spp. as well as fumonisin contamination level of maize ... -
Genetic engineering and light quality as tools to control shoot elongation in poinsettia (Euphorbia pulcherrimaWilld ex Klotzsch)
(PhD Thesis;2013:42, Doctoral thesis, 2013)Poinsettia (Euphorbia pulcherrima Willd ex Klotzsch) is a non-food and non-feed, vegetatively propagated ornamental plant which is among the economically most important ornamentals worldwide. Desirable plant height is one ... -
Genetics of Pooideae freezing tolerance : an evolutionary perspective
(PhD Thesis;2010:37, Doctoral thesis, 2010)Freezing tolerance is an important agricultural trait for forage and cereal grasses belonging to the Pooideae sub-family. Many plants, including the Pooideae grasses, go through a cold acclimation (CA) process when exposed ... -
Growth, hydraulic and transcriptomic responses to high air humidity and the involvement of abscisic acid (ABA)
(PhD Thesis;2021:65, Doctoral thesis, 2021)The aerial environment, which includes relative air humidity (RH), temperature, vapour pressure deficit (VPD) and CO2 availability, affects plant growth and development in many ways. The aerial environment determines ... -
