Influence of genotype and climatic environment on fruit yield and chemical composition of black currant (Ribes nigrum L.)
(PhD Thesis;2016:40, Doctoral thesis, 2017-07-07)Black currant (Ribes nigrum L.) is a widely cultivated soft fruit species, which is renowned for its high berry concentrations of proven, or presumed, health-promoting compounds. Over the last years, there has been a ... -
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, ... -
Impact of UV radiation on plant growth and development in different climatic regimes
(PhD Thesis;2015:19, Doctoral thesis, 2017-07-06)Ultraviolet (UV) radiation has various effects on the growth, morphology, and biochemical composition of plants. Currently, there is an increasing interest in the manipulation of UV radiation in glasshouses, polythene ... -
The effects of temperature during grain filling on gluten quality of bread wheat (Triticum aestivum L.)
(PhD Thesis;2015:35, Doctoral thesis, 2017-07-06)Wheat production in Norway occurs at the highest latitudes among wheat production areas worldwide, and with lower growth temperature. The proportion of Norwegian wheat in total wheat consumed for food has increased from ... -
Health-related compounds in broccoli (Brassica oleracea L. var. italica) as affected by postharvest temperature, light and UV-B irradiation
(PhD Thesis;2016:05, Doctoral thesis, 2017-07-06)Broccoli (Brassica oleracea L. var. italica) belongs to Brassica vegetables, consumption of which has been shown to reduce the risk of several types of cancer and cardiovascular disease mortality in epidemiological studies. ... -
Winter hardening of Norwegian perennial forage crops in a prolonged growing season
(PhD Thesis;2015:88, Doctoral thesis, 2017-07-06)Current climate change models predict that the temperature increase due to global warming will be greatest at higher northern latitudes. Most probably, temperature will increase more during autumn and winter than summer, ... -
Potato quality during storage: effect of maturity level and ventilation strategies : studies on the storage disease Fusarium dry rot
(PhD Thesis;2016:31, Doctoral thesis, 2017-07-06)Storage losses of Norwegian potatoes are estimated to approximately 10%. The losses are caused by respiration, transpiration, germination and diseases. These are processes that can be managed by controlling storage conditions ... -
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 ... -
Winter hardiness and management of velvet bentgrass (Agrostis canina) on golf greens in the Nordic climate
(PhD Thesis;2011:14, Doctoral thesis, 2011)Major concerns for the introduction of velvet bentgrass (Agrostis canina) on Nordic golf courses are whether current cultivars have sufficient winter hardiness, and if it is possible to control the rapid thatch formation ... -
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 ... -
Therapeutic horticulture for clinical depression in a Green Care context : prospective studies on mental health benefits, active components and existential issues
(PhD Thesis;2010:28, Doctoral thesis, 2010)Historically, asylums were surrounded by gardens, parks and open landscapes, and patients often participated in horticultural activities. Horticultural therapy and therapeutic horticulture are today widely known therapeutic ... -

(PhD Thesis;2010:19, Doctoral thesis, 2010)This thesis covers the assessment of anthracnose incidence and severity in Ethiopia, characterisation of Colletotrichum sublineolum isolates from different sorghum regions of Ethiopia, studying the impact of four selected ... -
Vernalization and photoperiodic regulation of flowering time and population genetic stucture of Norwegian populations of Arabidopsis thaliana
(PhD Thesis;2009:44, Doctoral thesis, 2009)Natural environmental conditions vary across seasons and therefore timing of flowering is a major determinant of plant reproductive success and a trait with a potentially high adaptive value. Plants have developed mechanisms ... -
Use of supplemental lighting towards efficient management of powdery mildew in greenhouse roses
(PhD Thesis;2009:22, Doctoral thesis, 2010)Powdery mildew caused by the Podosphaera pannosa is one of the most widespread and destructive diseases in roses and has been an increasing problem in Norwegian rose production due to lack of disease resistant cultivars. ... -
