Effects of artificial ultraviolet B radiation on the macrophyte Lemna minor: a conceptual study for toxicity pathway characterization
Xie, Li; Solhaug, Knut Asbjørn; Song, You; Johnsen, Bjørn; Olsen, Jorunn Elisabeth; Tollefsen, Knut-Erik (Peer reviewed; Journal article, 2020)Macrophytes inhabit waterways around the world and are used in hydroponics or aquaponics for different purposes such as feed and wastewater treatment and are thus exposed to elevated levels of UVB from natural and artificial ... -
Effects of temperature and photoperiod on photosynthesis in everbearing strawberry
Rivero, Rodmar Isak; Sønsteby, Anita; Solhaug, Knut Asbjørn; Heide, Ola M.; Remberg, Siv Fagertun (Peer reviewed; Journal article, 2021)There is little knowledge about photosynthesis in everbearing strawberry cultivars. We therefore grew three everbearing strawberry cultivars in daylight phytotron compartments at temperatures of 9, 15, 21 and 27°C and ... -
Effekt av ulike lyskilder på planter i kontormiljø
Funderud, Helene (Master thesis, 2016-08-11)For å undersøke hvordan forskjellige lyskilder påvirket vekst hos innendørsplanter i kontormiljø ble det satt opp et forsøk med 3 forskjellige lyskilder. Lysrør, metallhalogen og LED-belysning ble montert i respektive ... -
Elevated air humidity increases UV mediated leaf and DNA damage in pea (Pisum sativum) due to reduced flavonoid content and antioxidant power
Innes, Sheona Noemi; Arve, Louise Elisabeth; Zimmermann, Boris; Nybakken, Line; Melby, Tone Ingeborg; Solhaug, Knut Asbjørn; Olsen, Jorunn Elisabeth; Torre, Sissel (Peer reviewed; Journal article, 2018)Growth in high relative air humidity (RH, >85%) affects plant morphology and causes diminished response to stomatal closing signals. Many greenhouses are prone to high RH conditions, which may negatively affect production ... -
Erioderma pedicellatum : an ecophysiological study of a globally threatened pioneer lichen on thin spruce branches in old forests
Nilsson, Alexander Ruhs (Master thesis, 2021)Lichen extinction occurs at a fast rate due to human activity, and species yet to be discovered are likely go extinct every year. Many species close to extinction may still be rescued by conservation management based on ... -
Evaluation of the aquatic bryophyte Fontinalis antipyretica for laboratory and field toxicity studies
Dahl, Lina Agneberg (Master thesis, 2021)Fontinalis antipyretica is an ecologically important aquatic moss in boreal streams. Bioassays using this species provide information of effects at the base of the food chain. The present study assessed toxicological effects ... -
Functional characterization of Pseudoidium neolycopersici photolyase reveals mechanisms behind the efficacy of nighttime UV on powdery mildew suppression
Pathak, Ranjana; Ergon, Åshild; Stensvand, Arne; Gislerød, Hans Ragnar; Solhaug, Knut Asbjørn; Cadle-Davidson, Lance; Suthaparan, Aruppillai (Peer reviewed; Journal article, 2020) -
Functional growth analysis of ‘Sonata’ strawberry plants grown under controlled temperature and daylength conditions
Sønsteby, Anita; Solhaug, Knut Asbjørn; Heide, Ola M. (Journal article; Peer reviewed, 2016)In order to investigate the relationship between environmental conditions and vegetative growth and reproductive development in the strawberry, freshly rooted runner plants of the cultivar ‘Sonata’ were grown in a phytotron ... -
Growth analysis of the everbearing strawberry 'Delizzimo' under controlled temperature and photoperiod conditions
Rivero, Rodmar Isak; Sønsteby, Anita; Heide, Ola M.; Solhaug, Knut Asbjørn; Remberg, Siv Fagertun (Journal article; Peer reviewed, 2022) -
Growth, hydraulic and transcriptomic responses to high air humidity and the involvement of abscisic acid (ABA)
Innes, Sheona Noemi (PhD Thesis;2021:65, Doctoral thesis, 2021)The aerial environment, which includes relative air humidity (RH), temperature, vapour pressure deficit (VPD) and CO2 availability, affects plant growth and development in many ways. The aerial environment determines ... -
Hot water and cutting for control of Impatiens glandulifera
Oliver, Benedikte Watne; Berge, Therese W.; Solhaug, Knut Asbjørn; Fløistad, Inger (Peer reviewed; Journal article, 2020)Ornamental jewelweed (Impatiens glandulifera Royle) is an alien invasive plant in Europe.
