Tomato, watermelon prove most efficient at CO2 accumulation
Scientists compared carbon fixation by five plant species under conditions of salinity. Salt tolerance and its relationship with plant CO2 fixation were analyzed. The net photosynthetic rate, gS, and transpiration rate were measured at atmospheric CO2 during the daytime and related to the total chlorophyll, carbon, and mineral contents of the crops. Tomato and watermelon proved to be more efficient in CO2 fixation than the other crops tested.
