Fig. 5. Band location of the derivative chlorophyll index (DCI) calculated as D₇₀₅/D₇₂₂, developed to track changes due to the double peak generated by the suggested effects of pigment and chlorophyll fluorescence at the canopy level in stressed vegetation (healthy site, GY41: F_v/F_m = 0.81; C_a+b = 38.8 µg/cm²; stressed site, MD35: F_v/F_m = 0.75; C_a+b = 19.08 µg/cm²)
