Journal ArticleDOI
Climatic adaptation in Picea abies progenies is affected by the temperature during zygotic embryogenesis and seed maturation
Øystein Johnsen,Carl Gunnar Fossdal,Nina Elisabeth Nagy,Jørgen A. Mølmann,Ola Gram Dæhlen,Tore Skrøppa +5 more
TL;DR: It is hypothesize that temperature during zygotic embryogenesis and seed maturation regulates an 'epigenetic memory' in the progeny, involving differential expression of genes that may regulate bud phenology, cold acclimation and embryogenesis in Norway spruce.
Journal ArticleDOI
Effects of red, far‐red and blue light in maintaining growth in latitudinal populations of Norway spruce (Picea abies)
TL;DR: The results suggest that phytochrome(s) are the primary photoreceptors in high irradiance responses maintaining growth in Norway spruce seedlings.
Journal ArticleDOI
Low night temperature and inhibition of gibberellin biosynthesis override phytochrome action and induce bud set and cold acclimation, but not dormancy in PHYA overexpressors and wild-type of hybrid aspen
Jørgen A. Mølmann,Daniel K. A. Asante,John Beck Jensen,Maria N. Krane,Arild Ernstsen,Olavi Junttila,Jorunn E. Olsen +6 more
TL;DR: It is shown that the SD-requirement for bud set and cold hardening can be overcome in hybrid aspen by low night temperature and inhibition of gibberellin (GA) biosynthesis, which might suggest separate signalling pathways from phytochrome regulating the induction of cold/cold hardiness and bud dormancy in hybrids aspen.
Journal ArticleDOI
Metabolism of gibberellin A19 is under photoperiodic control in Populus, Salix and Betula, but not in daylength‐insensitive Populus overexpressing phytochrome A
Jørgen A. Mølmann,A. T. Berhanu,Svein Kristian Stormo,Arild Ernstsen,Olavi Junttila,Jorunn E. Olsen +5 more
TL;DR: The present data are in favour of a photoperiodic regulation of the metabolism of GA 19 in vivo in the woody species S.pentandra, hybrid aspen and silver birch.
Journal ArticleDOI
Influence of Arctic light conditions on crop production and quality.
Jørgen A. Mølmann,Sigridur Dalmannsdottir,Anne Linn Hykkerud,Timo Hytönen,Amos Samkumar,Laura Jaakola +5 more
TL;DR: In this article, a review compiles information from the reports about the effects of light conditions at high latitudes on growth, biomass production, flowering and quality of the crop plants and discusses the gained knowledge and the key gaps to be addressed.
