Effect of seed treatment with putative defence priming chemicals on defence-related gene expression and pathogen resistance in Norway spruce (Picea abies) seedlings
(Master thesis, 2020)Chemical seed treatment may be a simple method to protect conifer seedlings from pests and pathogens in plant nurseries and forest stands. In this study, I tested the ability of eight putative defence priming chemicals ... -
Effect of short time temperature alteration on two key reproduction hormone levels of Nile tilapia (Oreochromis niloticus)
(Master thesis, 2020)This study investigates the effects of rapid and short temperature change on the levels of the hormones testosterone and estradiol-17β and the subsequent effect on egg maturation in Nile tilapia (Oreochromis niloticus). ... -
The effect of Silene acaulis on soil bacterial communities across elevational and latitudinal gradients in Scandinavia
(Master thesis, 2022)Microbes are ubiquitous, extremely diverse, and contribute to important ecosystem functions. Soil bacterial communities, in particular, play an important role in carbon and nutrient cycling, through decomposition and carbon ... -

Effect of supplementation of pelleted hazel (Corylus avellana) leaves on blood antioxidant activity, cellular immune response and heart beat parameters in sheep
(Peer reviewed; Journal article, 2019)Hazel leaves (Corylus avellana) fed to sheep resulted in decreased methane emissions without negatively affecting feed intake and were found to have antioxidant properties in vitro. The objective of this study was to ... -
Effect of temperature and photoperiod preconditioning on flowering and yield performance of three everbearing strawberry cultivars
(Peer reviewed; Journal article, 2022)Environmental control of flowering in everbearing strawberry is well known, while the optimal commercial raising conditions for high and continuous yield remains unsettled. We exposed freshly rooted plants of cultivars ... -
Effect of temperature during flowering, pod set, and seed development on yield components and accumulation of protein, starch, and low molecular weight carbohydrates in two faba bean (Vicia faba L.) cultivars
(Peer reviewed; Journal article, 2023)The aim was to explore the impact of temperature during seed development on yield performance and seed quality in faba bean when grown at cool temperatures representative for high latitude regions. Two varieties, an early ... -
Effect of temperature-photoperiod interaction on growth and winter bud development in Norway spruce (Picea Abies)
(Master thesis, 2020)Woody species growing in temperate and boreal regions, like Norway spruce (Picea abies) have to enter dormancy to survive winter and freezing temperatures, while simultaneously maximizing their growing period. Dormancy is ... -
