Effects of abiotic and biotic stresses on plant photosynthetic performance lead to fitness yield decrease. The maximum quantum efficiency photosystem II (F v/F m) is a parameter chlorophyll fluorescence (ChlF) classically used track changes in performance. Despite recent technical methodological advances ChlF imaging, the spatio-temporal heterogeneity F m still awaits for standardized accurate quantification.
