Concentrations of Cd, ALA, Si and Mn were 30 mg kg-1 CdCl2, 10 mg L-1 ALA, 200 mg kg-1 Na2SiO3·9H2O and 100 mg kg-1 MnSO4, respectively. Data are the means of three replicates (mean ± SE). Small letters indicate significant differences at P< 0.05 by Duncan’s multiple range tests. DW, Dry weight; FW, Fresh weight.
