FIGURE 3.

Changes in reactive oxygen species (ROS) and lipid peroxidation of F. rufa plants under drought and rewatering. (A) superoxide anion (${\mathrm{O}}_{\mathrm{2}}^{\mathrm{•}\mathrm{-}}$) producing rate, (B) hydrogen peroxide (H₂O₂), and (C) lipid peroxidation (MDA content). Well-watered (WW, open bars), moderate drought (MD, gray bars), and severe drought (SD, closed bars). Data are the means of four replicates with SE shown by vertical bars. Different letters within the same stage indicate significant differences (P < 0.05) according to Duncan’s test.
