An evaluation of cyanobacteria as a repellent against the turnip fly (Delia floralis Fallén)
(Master thesis, 2017)The turnip root fly (Delia floralis) lives in the northern hemisphere and is a major pest on Brassica crops. D. floralis can cause severe economical and production damage to Brassica crops if left uncontrolled. The main ... -
Characterisation of fructan accumulation in grasses and its implication for cold adaptation and overwintering
(Master thesis, 2021)Fructans are fructose-based oligo- and polysaccharides that occur in many plants in temperate climates. Beside its main function as storage carbohydrate, fructan has been suggested to play a role in temperate adaptations, ... -
Evolution of growth rates in Pooideae (Poaceae)
(Master thesis, 2016)The temperate grasses in the subfamily Pooideae (Poaceae) has a limited distribution range The species are mainly distributed to the Northern Temperate regions and are known to be adapted to the strong seasonality this ... -
Five-year numerical response of saproxylic beetles following a dead wood pulse left by moth outbreaks in northern Scandinavia
(Master thesis, 2017)Saproxylic insects are important for the decomposition of dead wood, and therefore crucial for maintaining healthy forest ecosystems. There is, however, little knowledge about their ability to respond to massive resource ... -
Impact of light regimes on growth and tipburn formation in lettuce (Lactuca Sativa L. ‘Frillice’) and the use of NDVI for early detection of tipburn.
(Master thesis, 2020)The work in this master thesis was undertaken in order to add to invesitage how light schedules impact the growth and the formation of tipburn in ‘Frillice’ lettuce when grown hydroponically in controlled growth chambers, ... -
Influence of compost, vermicompost and digestate on nutrient status and secondary metabolites, Lactuca sativa L. as a model
(Master thesis, 2018)Peat is the most commonly used substrate in greenhouse cultures due to its predictability and performance. Though significant environmental costs and CO2 emissions are associated with harvesting of peat. It is therefore ... -
Kan ulike salter og fysiologisk alder hos lagringspotet påvirke fasthet til potetbiter i potetsalat?
(Master thesis, 2017)Poteter blir høstet om høsten og lagret slik at de kan brukes hele året. Mills bruker på denne måten ferske poteter i potetsalat hele året. Etter kundeklager på for harde potetbiter i potetsalat har Mills begynt arbeidet ... -
Molekylærgenetisk karakterisering av vernaliseringsrespons i PACMAD-gras
(Master thesis, 2018)Many plants rely on a mechanism called vernalisation response to match reproductive output with favourable environmental conditions. This trait is an important adaptation to seasonal climates, like for example at high ... -
Multitrophic effects of the relationship between a plant growth-promoting rhizobacteria (Bacillus amyloliquefaciens) and arugula (Eruca sativa) on the predator Doru luteipes, using Plutella xlyostella and Spodoptera frugiperda
(Master thesis, 2018)Background. Plant growth-promoting rhizobacteria (PGPR) provide several benefits to plants, such as faster growth, larger yields and resistance to pests. When attacked by herbivores, plants defend themselves in various ... -
Phenotypic characterization and ploidy level determination of perennial ryegrass (Lolium perenne L.) gene bank accessions and cultivars
(Master thesis, 2020)Perennial ryegrass (Lolium perenne L.) is the most grown perennial grass species all over the world, because of the rapid regrowth and good nutritional composition. Winter survival is challenging when growing perennial ... -
Review of CRISPR-assosiated proteins, their functions and patent situations
(Master thesis, 2019)CRISPR-Cas (Clustered Regularly Interspaced Short Palindromic Repeats) systems are a new revolutionary gene editing tool. CRISPR-Cas was originally discovered as a defense mechanism in bacteria and archaea. CRISPR has ... -
Yield and fruit quality of Norwegian production-ready strawberry plants
(Master thesis, 2017)Cold-stored large strawberry plants with high yield potential (production-ready plants) was propagated at two locations: ‘Oppland’, a South-East Norwegian location (60° 40’ N; 10° 52’ E; 250 m altitude) and ‘Rogaland’, a ...
