Salt-tolerant crops show higher capacity for carbon fixation
Date:12/12/2011

al composition data showed greater increases of sodium in both roots and leaves of melon and pepper when plants were treated with NaCl compared with the rest of the species.

"Almost all of the results obtained showed that lettuce, pepper, and melon are less adapted to saline conditions and that these crops seem to be less efficient in CO2 fixation and, therefore, have less capacity for carbon accumulation", noted corresponding author Micaela Carvajal. "We concluded that the species more tolerant of saline conditions (tomato and watermelon) showed a higher capacity for fixation of atmospheric CO2 than the sensitive species (lettuce, melon, and pepper). These results seem to be related to the capacity of each species to maintain the photosynthetic processes and gS in stressing situations."
