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.

UV4Plants conference in Göttingen

The last few days saw the members of the UV4Plants Association gather in Göttingen, Germany for the 5th Network Meeting of the UV4Plants Association. Natalie Cunningham, a PhD researcher from Biological, Earth and Environmental Sciences at UCC in Cork, presented her work on the effects of UV-B on the morphology of plants. Professor Marcel Jansen presented his work on "Plants, plastics and UV-B". He explained how UV-mediated breakdown of plastics are having an unexpected yet important impact on plants.

New paper: UV exposure makes plants more stress resistant

A new paper has been published in Photochemical and Photobiological Sciences, describing how plants exposed to a low dose of UV irradiance can alleviate drought effect caused by a change in humidity.
