    • Effects of supplemental LED light quality and reduced growth temperature on swede (Brassica napus L. ssp. rapifera Metzg.) root vegetable development and contents of glucosinolates and sugars 

      Mølmann, Jørgen A; Hansen, Espen Holst; Johansen, Tor Jacob (Journal article; Tidsskriftartikkel; Peer reviewed, 2020-10-04)
      Background - Low growth temperatures and the special light qualities of midnight sun in northern Scandinavia, have both been shown to improve eating quality of swede root bulbs. To study the combined effect of these factors on root development and sensory-related compounds, plants were grown in phytotron under different 24 h supplemental light-emitting diode (LED) light colours, at constant 15 °C, ...

    • Influence of Arctic light conditions on crop production and quality 

      Mølmann, Jørgen A; Dalmannsdottir, Sigridur; Hykkerud, Anne Linn; Hytönen, Timo; Samkumar, Amos; Jaakola, Laura (Journal article; Tidsskriftartikkel; Peer reviewed, 2021-04-10)
      The natural light conditions above the Arctic Circle are unique in terms of annual variation creating special growth conditions for crop production. These include low solar elevations, very long daily photosynthetic light periods, midnight sun/absence of dark nights, and altered spectral distribution depending on solar elevation. All these factors are known to affect the growth and the metabolism ...
