Light quality for crop flavour, colour and plant shape


Those of us lucky enough to have holidayed in the Mediterranean may recall the strong, fragrant smell of wild rosemary or thyme growing on a sun drenched, rocky coast. Indeed, the link between sun exposure and crop quality is well known and marketed through concepts such as “sun ripened tomatoes”. So, is there any truth in sun ripened crops having a better aroma, colour and overall flavour, and can we, based at more northerly latitudes, improve our crops to capture that Mediterranean feel?

Our project aims to improve crop lighting to better reflect natural sunlight, and using the benefits of light to improve the crop's colour, flavour and plant architecture.

UV regulates plant architecture of in vitro-grown mint plants

A new paper published in the journal Agronomy explains that exposing Mentha spicata (L.) plants to UV-B radiation while growing in tissue culture containers, changes the architecture of the plants. These changes were associated with significant alterations in concentrations of several hormones, indicating a regulatory rather than a stress response to UV-B.

Video: Shining a light on healthier food

Our multi-discipline research project has successfully developed a lighting system to replace the nutritional value lost when plant food is grown indoors, away from UV light. University College Cork (UCC) has announced that the collaborative project, funded by Science Foundation Ireland, has evaluated innovative UV-LED systems in plant growth trials and is currently looking for potential partners from commercial horticulture to further develop this UV technology.
