“ NSAID treatments decreased … chlorophyll and carotenoid content, and chlorophyll fluorescence parameters such as minimum fluorescence yield (F0), maximum fluorescence yield (Fm), maximum photochemical quantum yield (Fv/Fm), PSII (photosystem II) effective quantum yield [Y(II)], photosynthetic electron transfer rate (ETR), and the photochemical quenching (qP), were also adversely affected.”
