Lipid peroxidation measured by TBARS (thiobarbituric acid reaction) test in 5-day-old seedlings (a) and 20-day-old plantlets (b) grown from irradiated rice seeds in the absence/presence of NaCl. Hydrogen peroxide (H₂O₂) accumulation in 5-day-old seedlings (c) and 20-day-old plantlets (d) grown from irradiated rice seeds in the absence/presence of NaCl, as evidenced by DAB (3,3′-diaminobenzidine) staining. Values are expressed as mean ± SD of three independent replications with 100 seeds for each replication. Significant differences between control and treatments are represented by asterisk (^∗𝑃<0.05; ^∗∗𝑃<0.01). NT: nontreated samples.
