Effect of seed treatment with putative defence priming chemicals on defence-related gene expression and pathogen resistance in Norway spruce (Picea abies) seedlings
Devos, Claire Celine (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 ... -
Effekter av metyl-jasmonat på frøanatomi og terpenkonsentrasjoner i små granplanter
Bryhn, Konrad Skåravik (Master thesis, 2019)Gransnutebillen (Hylobius abietis) er en stor skadegjører i plantefelt med gran (Picea abies), og i internasjonal sammenheng gjør den skade for millioner av euro hvert år. Samtidig har giftige insekticider, tidligere brukt ... -
Impacts of abiotic stress on priming of defense responses and pathogen resistance in Norway spruce
Hansen, Hristo Petrov (Master thesis, 2020)Norway spruce (Picea abies) is one of the most important tree species in Norway due to its high economic and ecological significance in forests. Pathogens, fungi and insects may have detrimental impacts on Norway spruce ... -
Priming of inducible defenses in Norway spruce : effects of putative defense priming chemicals on tree resistance against the bluestain fungus Grosmannia penicillata and insights into the underlying mechanisms
Huynh, Ngan Bao (Master thesis, 2021)Priming of inducible defenses in Norway spruce could be a cost-effective strategy to protect trees from herbivores and pathogens. In this study, my aim was to identify chemical priming agents that can increase the resistance ... -
Testing host choice of Ips typographus in Norway spruce and two North American spruce species, using field studies and lab analysis
Tanin, Sifat Munim (Master thesis, 2019)The spruce bark beetle Ips typographus is one of the most damaging pests in Europe’s boreal forests and cause catastrophic tree mortality during outbreaks. Norway spruce (Picea abies), an economically important forest tree, ... -
Vaksinering av gran : fysiologiske og morfologiske effekter av metyljasmonat
Skrautvol, Thomas Olufsen (Master thesis, 2018)Norway spruce (Picea abies) is in economic terms the most important tree in Norwegian forestry, and the rejuvenation of this species might in some cases become problematic because of harmful organisms in nurseries and ...
