  1. 5-d-old maize seedlings of ZD958 and ZJY1 were pre-incubated in the solution containing 0.65 mM CH4 for 1 d, and then transferred to half-strength Hoagland solutions with or without 20% PEG-6000 for 2 d. Afterwards, GSH and GSSG contents in the seedling roots were determined. Control seedlings were incubated in Hoagland solution alone. Data are presented as means ± SE (5 root parts per experiment performed three times). Within each set of experiments, bars with different letters denote significant differences according to multiple comparisons (P < 0.05).
