Effects of exogenous S on content of (A,D) glutathione (GSH); (B,E) oxidized glutathione (GSSG); (G,J) ascorbate (ASA); (H,K) dehydroascorbate (DHA); (C,F) GSH/GSSG ratio, and (I,L) ASA/DHA ratio in roots and leaves of Pakchoi seedlings suffered from Cd stress. The leaves and roots of three seedlings were separately collected in one replication and three independent biological replications were performed. Different letters indicates significant differences (p < 0.05). Units of GSH, GSSG, ASA and DHA content, nmol·g·FW⁻¹.
