May 01, 2013 · They observed that gold concentration ranging from 20 to 80 mgAu/L did not significantly affect C. linearis plant growth. The concentration of gold in the plants increased as the age of the plant increased. The gold concentrations in leaves for the 20, 40, 80, and 160 mgAu/L treatments were found 32, 60, 62, and 179 mgAu/kg DM, respectively.
