To investigate the responses of plant photosynthesis and chlorophyll fluorescence to excessive sulfur
fumigation stress (Sulfur) alleviated by pre-treated salt in the soil (Salt), seedlings of a tomato cultivar
(Solanum lycopersicum L. ‘Money Maker’) were exposed to the Sulfur with or without the Salt treatment
for 15 h. Leaf fresh weight, dry weight, chlorophyll (Chl) content, carotenoid (Car) content,
photosynthesis and chlorophyll fluorescence parameters were measured.
