The project was funded by a research grant to E.R. from GUDP (Danish Ministry of Food, Agriculture and Fisheries) for the project Intelligent Light: LED technology for regulation of plant reactions (https://www.teknologiudvikling.dk/gudp; grant #34009-16-1104), supported by the MSc program of University of Copenhagen for S.G.S. This project was also funded by research grants to Å.S. from the Knowledge Foundation (http://kks.se; grant #20130164), the Swedish Research Council Formas (http://formas.se/en; grant #942-2015-516), and by The Carl Trygger Foundation for Scientific Research, Sweden (https://www.carl-tryggersstiftelse.se; grant #CTS21:1666). The Faculty for Business, Science and Technology at Örebro University also funded the research and V.C.A., Å.S., and T.H., were also provided with funding from Örebro University Vice Chancellor's strategic research programme on ‘Food and Health’.

The development of light emitting diodes (LED) gives new possibilities to use the light spectrum to manipulate plant morphology and physiology in plant production and research. Here, vegetative Chrysanthemum × morifolium were grown at a photosynthetic photon flux density of 230 μmol m−2 s−1 under monochromatic blue, cyan, green, and red, and polychromatic red:blue or white light with the objective to investigate the effect on plant morphology, gas exchange and metabolic profile. After 33 days of growth, branching and leaf number increased from blue to red light, while area per leaf, leaf weight fraction, flavonol index, and stomatal density and conductance decreased, while dry matter production was mostly unaffected. Plants grown under red light had decreased photosynthesis performance compared with blue or white light-grown plants. The primary and secondary metabolites, such as organic acids, amino acids and phenylpropanoids (measured by non-targeted metabolomics of polar metabolites), were regulated differently under the different light qualities. Specifically, the levels of reduced ascorbic acid and its oxidation products, and the total ascorbate pool, were significantly different between blue light-grown plants and plants grown under white or red:blue light, which imply photosynthesis-driven alterations in oxidative pressure under different light regimens. The overall differences in plant phenotype, inflicted by blue, red:blue or red light, are probably due to a shift in balance between regulatory pathways controlled by blue light receptors and/or phytochrome. Although morphology, physiology, and metabolism differed substantially between plants grown under different qualities of light, these changes had limited effects on biomass accumulation.
