Root–shoot transfer = Cd concentrations in shoot ∕ Cd concentrations in roots. Soil–root transfer = Cd concentrations in roots ∕ available soil Cd (mg kg).
% Removed Cd = Cd uptake by shoot ∕ total soil Cd.
Means (±standard deviation, n = 4) denoted by different letters are significantly different at P <0.05.
