Red light exposure for 5 d maximized net CO2 assimilation, radiation-use efficiency, and biomass accumulation in Azolla filiculoides, while blue light reduced symbiont presence and biomass.
- Why it matters: Light spectrum can reshape growth versus specialized metabolism in this fast-acclimating fern, but the linked physiological and metabolomic trade-offs and antioxidant outcomes needed direct comparison.
- What they did: Plants were grown under monochromatic blue or red, two blue:red mixtures, and solar-like spectra at two irradiance levels, then assessed with gas exchange, pigments, oxidative markers, antioxidant assays, and untargeted high-resolution mass spectrometry.
- The result: Blue light preferentially increased phenolic acids and low-molecular-weight phenolics linked to stronger antioxidant response, whereas 4:1 blue:red boosted flavonoid classes and lowered hydrogen peroxide and membrane lipid peroxidation versus blue alone.
