Sulfur Dioxide Enhances Endogenous Hydrogen Sulfide Accumulation and Alleviates Oxidative Stress Induced by Aluminum Stress in Germinating Wheat Seeds

Figure 4

Effect of SO₂ donor pretreatment on the activities of POD (a), CAT (b), APX (c), and LOX (d) in germinating wheat grains under 15 mM Al stress. Grains were treated and the number or letters presented are the same as mentioned in Figure 2. Al: Al stress without SO₂ pretreatment; S + Al: Al stress with SO₂ pretreatment.
