Figure 1.

Effects of NO and NH₄⁺:NO₃⁻ ratio on membrane lipidation damage in mini Chinese cabbage leaves under low light stress. The seedlings cultivated in black containers filled with different solutions, CK (NH₄⁺:NO₃⁻ = 0:100); N (NH₄⁺:NO₃⁻ = 10:90); SNP (100 μmol/L); N + Hb (0.1%); N + L-NAME (25 μmol/L); N + NaN₃ (50 μmol/L) were treated for 7 days. Capital letters (A–C) represent MDA content, H₂O₂ content, O₂⁻ content, respectively. Bars indicated the SE (n = 3). Significant differences (p < 0.05) between treatments are indicated by different letters, for low light condition.
