Biosensor, based on canopy-level chlorophyll fluorescence, for improving lamp light use efficiency, growth control and stress detection in controlled environment agriculture – results and analysis from greenhouse experiments at SLU

Seminar by Daniel Bånkestad, Heliospectra

Interestingly, while all environmental factors that drive crop growth are being controlled and monitored in high-tech greenhouses, there are no sensors commonly used that can directly monitor plant performance and well-being. Chlorophyll fluorescence is an interesting signal to monitor in that regard as it is closely linked to photosynthesis. It is also well studied in plant science. However, most conventional approaches of measuring chlorophyll fluorescence are based on high-intensity flashes of light, and therefore difficult to apply in a production environment. In this innovation project we are testing a novel canopy-level fluorescence sensor for the applications of improving lamp light use efficiency, growth control and stress detection in controlled environment agriculture. A greenhouse trial on lettuce, with and without drought treatment, was conducted at SLU, Alnarp, and a replicate trial was conducted in an indoor environment in Heliospectra Plant Lab. Results from the trials will be presented and discussed.
