Fig. 3. — Time-dependent effect of Si on Cd accumulation in shoots and roots. (A, B) Cd concentration in the shoots (A) and roots (B) of lsi1 and its wild type (WT1); (C, D) Cd concentration in the shoots (C) and roots (D) of lsi2 and its wild type (WT2). Seedlings (22 d old) of lsi1, lsi2, and their wild types were exposed to a nutrient solution containing 1 µM Cd with or without 1 mM Si for 1, 3, 5, and 9 d. Roots and shoots were harvested for determination of Cd concentration by ICP-MS. Data are means±SD (n=4). Different lower-case letters indicate significant difference at P<0.05 by Duncan’s test.
