Changes in Photosynthesis, Yield, and Quality of Baby Lettuce under Salinity Stress

The objective of this work was to study the responses of two baby lettuce ( Lactuca sativa L.) cultivars, namely, green Paris Island and red Sanguine, to different NaCl concentrations (0, 5, 10, and 20 mM). The study was conducted in a floating system and plants were harvested at the stage of 5-6 leaves, outside leaf 6-10 cm in length (25 and 31 days after sowing for green and red lettuce, respectively). Photosynthetic parameters (photosynthesis...
