Identification of red clover (Trifolium pratense L.) SNPs whose allelic versions appear with different frequency in pure stands and in mixtures with grasses, using GBS and CAPS-markers
(Master thesis, 2018)In this thesis I`m trying to uncover if there is any genetic difference between red clover (Trifolium pratense L.) populations grown in pure stands with only red clover and in mixed stands, where red clover is grown together ... -
Identification of sperm parameters and gene variants influencing boar fertility
(PhD Thesis;2018:37, Doctoral thesis, 2018)Boar fertility has a major impact on overall pig reproductive efficiency, and good semen quality is essential for successful fertilization and proper embryo development. Thus finding semen characteristics that can predict ... -
Identifisering av kromosomområder som kontrollerer tidspunkt for stengelstrekning i rødkløver med bruk av Genotyping by Sequencing (GBS)
(Master thesis, 2016)En populasjon rødkløver av (Trifolium pratense L., sorten «Lea»), ble karakterisert for tidspunkt for begynnende stengelstrekning (dager til strekning – DTS). Dette er det første synlige steget i overgangen fra vegetativ ... -
Identifisering og karakterisering av gener assosiert med fettsyresammensetningen i melk
(Master thesis, 2012-09-11)Sammendrag Selv om helseeffekten av melkekonsum er omdiskutert, består helmelk av en betydelig fraksjon mettede fettsyrer som i seg selv har vist seg å være forbundet med hjertesykdom og overvekt. Tidligere studier i ... -
Identifying inoculation methods for screening of resistance to Fusarium langsethiae in selected oat varieties
(Master thesis, 2016-11-22)F. langsethiae is reported as the main producer of HT-2+T-2 toxins in Norwegian oats (Hofgaard et al., 2016). This investigation aimed to identify whether ranking of oat varieties according to the content of HT-2+T-2 toxins ... -
Ikkje-destruktive målemetodar på eple
(Master thesis, 2016-08-11)Rett haustetidspunkt er essensielt for å oppnå best mogeleg kvalitet i eple. For tidleg eller for sein hausting kan føre til lågare sensorisk kvalitet og kortare haldbarheitstid på lager. I dette forsøket vart det undersøkt ... -
Impact of additional blue light in the production of small plants of Abies laciocarpa and Picea abies propagated by seeds and seedlings
(Master thesis, 2016-04-01)The goal of this study was to examine how additional blue light affected growth and development of Picea abies and Abies laciocarpa seedlings and stem cuttings. The experiment was conducted at the Center for climate regulated ... -
Impact of agricultural landscape on honey reserves in bee colonies
(Master thesis, 2016-11-23)Intensive farming systems are now scarce floral environments leaving honey bees with low food availability at some periods. This scarcity could be related to the current recorded honeybee and wild pollinator decline. ... -
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, ... -
Impact of method choice on inbreeding coefficient estimation : a study of inbreeding in five beef cattle breeds in Norway
(Master thesis, 2023)In 2020 was genotyping implemented into the populations of Norwegian beef cattle breeds of Hereford, Charolais, Aberdeen Angus, Limousin and Simmental. This development provides an opportunity to estimate genomic inbreeding ... -
Impact of preharvest relative air humidity and postharvest modified atmosphere packaging on cucumber fruit quality
(Master thesis, 2017)The effect of relative air humidity (RH) was tested on the cucumber (Cocktail, Quarto F1 cultivar) plant growth, morphology and fruit quality in controlled growth chambers. The plants were grown at moderate RH (60%) and ... -
