FIGURE 2.

Seed priming increased endogenous H₂O₂ (A) and decreased MDA content (B) under chilling stress. Seed embryos were collected, respectively, at 0, 6, 24, 48, and 72 h after sowing, and six replications for each treatment at each sampling time were used. Different small letter(s) on the top of the bars indicated significant differences (p < 0.05, LSD) among treatments at the same time. Error bars indicated ± SE of mean (n = 6).
