  1. Values are mean ± standard deviation (n = 3). Values within a column followed by different lowercase letters show significant differences at P < 0.05. N.D., not detected under the detection limit of Cd: 2.5 μg/g, the same as below. TF = [the mean value of concentration in stems]/[the mean value of concentration in roots] for stems and [the mean value of concentration in leaves]/[the mean value of concentration in roots] for leaves.
