Superoxide dismutase activity (a) and malondialdehyde content (b) in leaves of Col-0, C24 and Eri. Leaf samples were harvested on day 0 (black bars, all plants under C 50) and day 7 (gray bars, C 50; white bars, SSF 1250/6). For each accession, asterisks indicate significant differences (P < 0.05) between day 0 (C 50) and day 7 of SSF 1250/6; plus signs indicate significant differences (P < 0.05) between C 50 and SSF 1250/6 on day 7. Data are means of four plants (±SE)
