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

Table 1

Inhibitory effect of Al stress on the germination of wheat grains. Wheat grains were exposed to 0, 5, 10, 15, 20, 25, 30, 60, or 90 mM AlCl₃ for 48 h.
