The American Society for Horticulture Science highlighted the lab’s research in a press release:

ASHS Press release on biofeedback system. The press release discusses the lab’s research on the development of a biofeedback system that can control how plant use light. The system uses chlorophyll fluorescence measurements to determine how efficiently the plants use the light absorbed by the leaves. Based on those data, we can measure the electron transport rate, a proxy for photosynthesis. The biofeedback system has a controller built in that can automatically adjust the light intensity coming from the LEDs to maintain a specific target electron transport rate. Our paper on this topic was recently published in the Journal of the  American Society for Horticulture Science.


A sweet potato crop is shown in the biofeedback system. Chlorophyll fluorescence measurements are taken on the plant on the right side to determine how efficiently the plant uses the light provided by LEDs. LED light levels are automatically adjusted to maintain specific levels of physiological activity. Credit: Michael Martin, UGA.
