Fig. 3. — Glutathione and non-protein thiol levels dependent on Cd and Si treatment of rice. Leaf (A, C) and root (B, D) contents of glutathione (A, B) and non-protein thiols (NPTs) (C, D) were measured in 42-day-old plants stressed with Cd for 4 d prior to Si application and subsequently treated with Si for another 4 d (labeled as 46-day-old plants), with appropriate controls. In (A and B), contents of glutathione in its reduced (GSH; solid) and oxidized (GSSG; hatched) form are presented, as is the oxidation state as a percentage above the columns. The data are means ±SD from three independent experiments and n=6 (A and B) and n=15 (C and D) determinations. Data groups of significant difference were calculated by t-test and are labeled with different letters (P<0.05).
