Effect of SNP alone or in combination with hydrogen sulfide (H₂S) inhibitors and scavengers on superoxide radical (O₂ ^.-) production rate (A) and hydrogen peroxide (H₂O₂) (B) contents in maize seedlings under non-HS and HS conditions. The data had at least three biological replicates and were tested using Duncan's multiple-range test at 0.05 significant level, which denote means ± standard error (SE). The bars with the different letters represent significant differences, while the same letters represent no significant difference.
