Fluorescence Ratio and Photochemical Reflectance Index as a Proxy for Photosynthetic Quantum Efficiency of Photosystem II along a Phosphorus Gradient

Sun-induced chlorophyll fluorescence (SIF) is one of the most promising remote-sensing signals to assess spatio-temporal variation in photosynthesis. Yet, it has been shown that the positive linear relationship of SIF and photosynthesis, often …
