“…In addition, it is well established that chlorophyll fluorescence (ChlF) may be applied to evaluate the physiological status of plants, in vivo, [12][13] as chlorophyll molecule is an intrinsic fluorophore present in green plants. Consequently, ChlF can been used for monitoring, directly or indirectly, the environmental impact induced by biotic or abiotic agents as the photosynthetic efficiency of plants usually decreases when placed under a stress condition [14][15][16][17].…”
