Effects of culture conditions on the photoautotrophic growth and biochemical composition of Chlamydomonas reinhardtii, as a potential source for hydrogen production
Markina, Daria (PhD Thesis;2014:85, Doctoral thesis, 2014)Hydrogen is a particularly attractive energy carrier, since its combustion produces water vapor only. The green microalga Chlamydomonas reinhardtii is able to produce hydrogen under sulfur-deficient anaerobic conditions ... -
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 ... -
Epigenetic effects of temperature during embryogenesis on climatic adaptation traits in Norway spruce (Picea abies) : studies of cold hardiness, gene expression and epigenetic marks
Slågedal, Kaia (Master thesis, 2019)Norway spruce (Picea abies) is known to have an epigenetic memory of temperature during embryogenesis, which affects phenological traits in the trees more than 20 years later. This memory was first shown in trees from ... -
Epitype-inducing temperatures drive DNA methylation changes during somatic embryogenesis in the long-lived gymnosperm Norway spruce
Viejo, Marcos; Tengs, Torstein; Yakovlev, Igor; Cross, Hugh; Krokene, Paal; Olsen, Jorunn Elisabeth; Fossdal, Carl Gunnar (Peer reviewed; Journal article, 2023)An epigenetic memory of the temperature sum experienced during embryogenesis is part of the climatic adaptation strategy of the long-lived gymnosperm Norway spruce. This memory has a lasting effect on the timing of bud ... -
The Expression of ELF4-Like Genes Is Influenced by Light Quality in Petunia
Fukuda, Naoya; Suenaga, Tomohiro; Miura, Erika; Tsukamoto, Atsuko; Olsen, Jorunn Elisabeth (Journal article; Peer reviewed, 2020) -
Growth, stomatal responses and postharvest characteristics of Rosa x hybrida : the influence of air humidity and light quality
Terfa, Meseret Tesema (PhD Thesis;2013:77, Doctoral thesis, 2013)Greenhouse production systems are important in the production of vegetables, herbs and ornamentals. Roses are among the most valuable crops in the greenhouse floriculture industry and are produced as pot plants or as a cut ... -
Impact of UV radiation on plant growth and development in different climatic regimes
Roro, Amsalu Gobena (PhD Thesis;2015:19, Doctoral thesis, 2017-07-06)Ultraviolet (UV) radiation has various effects on the growth, morphology, and biochemical composition of plants. Currently, there is an increasing interest in the manipulation of UV radiation in glasshouses, polythene ... -
Interactive effects of light quality and temperature on bud set and shoot elongation in Norway spruce (Picea ables) and Subalpine fir (Abies lasiocarpa).
Chiang Silva, Camilo Esteban (Master thesis, 2017-06-08)In recent studies, temperature was shown to modulate the response to short days (SD) in woody species. This is an important issue for plant production in zones with marked seasons. Furthermore, light quality affects bud ... -
