The physiological and genetic basis for yield formation and maturation behavior in faba bean (Vicia faba L.) under Norwegian climate
(PhD Thesis;2024:34, Doctoral thesis, 2024)Faba bean (Vicia faba L.) is a cool-season grain legume cultivated as a spring crop at higher latitudes such as the Nordic region, while in more southern regions and subtropical zones, it is grown as a winter or spring ... -
Oat breeding in the era of genomics : resistance against Fusarium
(PhD Thesis;2024:9, Doctoral thesis, 2024)In Norway, oat, along with wheat and barley, constitute one of the three major crops, valued as a break crop due to its minimal disease overlaps with the others. However, a significant threat to the cereal crops, particularly ... -
Cell fate and blade patterning during the early growth of Saccharina latissima sporophytes
(PhD Thesis;2023:14, Doctoral thesis, 2023)Saccharina latissima is a multicellular parenchymatic photosynthetic organism in the group of brown algae (Phaeophyceae). It belongs specifically to the group of kelps (Laminariales), a group that has recently acquired ... -
Identification of effectors of the plant pathogenic oomycete Phytophthora cactorum and characterisation of a candidate resistance gene from its host strawberry

Molecular dissection of the role of plant hormones in perennial shoot branching
(PhD Thesis;2023:17, Doctoral thesis, 2023)Shoot architecture in deciduous trees is determined by the apical meristems and the lateral branching. The formation of above-ground architecture perennials is regulated by a complex spatial-temporal regulation. For decades, ... -
A study of freezing tolerance in red clover (Trifolium pratense L.)
(PhD Thesis;2022:36, Doctoral thesis, 2022)The ability to tolerate freezing temperatures is one of the traits that allows successful overwintering of red clover (Trifolium pratense L.) at Nordic latitudes. Freezing tolerance (FT) is enhanced during a period of ... -
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 ... -
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 ... -
Yield and quality of vegetables fertilized with materials recycled from organic resources
(PhD Thesis;2021:64, Doctoral thesis, 2021)Agriculture, aquaculture, fishery and households generate large amounts of organic wastes with high contents of nitrogen (N) and other nutrients. Concurrently, supply of off-farm N resources into horticultural production ... -
Detection and validation of disease resistance QTL in wheat
(PhD Thesis;2018:02, Doctoral thesis, 2018)Powdery mildew (PM), Fusarium head blight (FHB) and Septoria leaf blotch (SNB) are devastating wheat diseases. Breeding of disease resistant varieties is an economical and environmentally friendly approach and is given ... -
Resistance to Septoria nodorum leaf blotch and the importance of sensitivity to necrotrophic effectors in Norwegian spring wheat
(PhD Thesis;2017:63, Doctoral thesis, 2017)Wheat is one of the most important food crops worldwide. In normal years, the proportion of food quality wheat grown in Norway exceeds 50 %. However, the quality and yield can be significantly challenged by unfavorable ... -
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 ... -
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 ... -
Resistance studies and genetic characterization of the barley : Pyrenophora teres pathosystem
(PhD Thesis;2017:52, Doctoral thesis, 2017)Net blotch is a major barley disease in Norway caused by the necrotrophic fungus Pyrenophora teres, which can cause yield losses of up to 40% under conducive conditions. Two forms of this pathogen, P. teres f. teres (Ptt) ... -
Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae) in Benin : its potential as a biological control agent for integrated aphid management in vegetable systems
(PhD Thesis;2013:41, Doctoral thesis, 2013)In Benin, vegetable producers’ reliance on toxic synthetic pesticides threatens the environment and human health. However, the recent discovery of Lysiphlebus testaceipes (Cresson) (Hymenoptera: Braconidae, Aphidiinae) in ... -
