Results of a study focused on inducing the color red in lettuce with the help of specific LED lighting strategies

Heliospectra want you to get the most out of your lights, that's why our Heliospectra Plant and Light Research Lab continuously work on finding new ways for you to optimize your business. We want to share some of their latest results from a study focused on inducing the color red in lettuce with the help of specific LED lighting strategies.

Two cultivars of red-green lettuce were studied: ”Amerikanisher brauner” and ”Galiano” grew under a Heliospectra LX602C light for 23 days in a growth unit in the Heliospectra Plant & Light Reseach Lab. After this period, two thirds of the plants were moved into two different growth units to be treated with different high-light treatments under either the Heliospectra LX602G or E602G. The high-light treatment entailed setting the lamps to provide a light intensity of 440 μmol/m2/s. The last third of the plants were kept as a control group in the unit with the initially selected light spectrum throughout the experiment.

Both the LX602G and E602G were efficient in inducing red coloration over 1 day of high-light treatment. The red coloring in the lettuce also increased with days of treatment. In conclusion, a lighting strategy which entails adjusting both light intensity and spectral quality shortly before harvest appears to have a positive influence on the coloring in lettuce.
