FIGURE 2.
Effect of PGPR [Pseudomonas aeruginosa (M1) & Burkholderia gladioli (M2)] and earthworms [Eisenia fetida (E)] on (A) superoxide anion, (B) hydrogenperoxide, (C) MDA content, and (D) electrolyte leakage in 10-day-old B. juncea seedlings, under chromium (Cr) stress. Data are presented as means of three independent replicates ± S.E (standard error). Different letters on the bar graphs indicate that mean values of the treatments are significantly different at p ≤ 0.05 (Tukey’s test).
