Effects of oxidative, salt and osmotic stresses on seedling germination. Surface sterilized cold treated seeds of the indicated plant lines were plated on agar media containing 0.5 x MS, 0.5% sucrose (control) supplemented with: a methyl viologen (MV) at 0 (yellow bars), 0.5 μM (orange bars) or 1 μM (brown bars); b NaCl at 0 (light green) or 150 mM (green) NaCl; c mannitol at 0 (light blue) or 300 mM (blue); d ABA at 0 (light purple) or 1 μM (purple). Green seedlings were scored 5 (a-c) or 6 (d) days later. Data shown are average ± SE. Statistically significant changes from WT plants (P < 0.05) are marked with asterisks
