The physiological responses of potato (Solanum tuberosum L. cv. Folva) to partial root-zone drying (PRD) were investigated in potted plants in a greenhouse (GH) and in plants grown in the field under an automatic rain-out-shelter. In the GH, irrigation was applied daily to the whole root system (FI), or to one-half of the root system while the other half(More)
This study aimed to assess varietal differences of quinoa’s tolerance to salinity and to investigate physiological mechanisms conferring these differences. Production of biomass in fourteen varieties grown under saline conditions was analysed in a pot experiment. For two contrasting varieties, the Danish variety Titicaca and the Bolivian variety Utusaya gas(More)
Potatoes and other Solanaceae species produce biologically active secondary metabolites called steroidal glycoalkaloids (GAs) which have antimicrobial, fungicidal, antiviral and insecticidal properties. GAs are, however, also toxic to animals and humans. Compared to wild species of potato, the elite cultivars primarily used for everyday consumption have(More)
WUE phenotyping and subsequent QTL analysis revealed cytosolic GS genes importance for limiting N loss due to photorespiration under well-watered and well-fertilized conditions. Potato (Solanum tuberosum L.) closes its stomata at relatively low soil water deficits frequently encountered in normal field conditions resulting in unnecessary annual yield losses(More)
BACKGROUND AND AIMS The C4 perennial grass miscanthus has been found to be less sensitive to cold than most other C4 species, but still emerges later in spring than C3 species. Genotypic differences in miscanthus were investigated to identify genotypes with a high cold tolerance at low temperatures and quick recovery upon rising temperatures to enable them(More)
To study maize (Zea mays L.) growth and soil nitrogen (N) dynamics in monocrop and intercropped systems in a North European climate and soil conditions with the support of a simulation model. Field data for 3 years at two sites/soil types in Denmark and three main factors: (i) cropping history (maize or grass-clover), (ii) maize monocrop or intercropped(More)
