  1. Mung bean seeds were presoaked with solutions containing 1.3 mM CH4, 100 μM SNP, 500 μM PTIO, alone or their combinations for 12 h, and then shifted to 20% PEG-6000 for another 48 h. Afterwards, reducing and soluble sugar contents, α-amylase and total amylase activities in germinating seeds, were determined. Treatment with distilled water was regarded as control (Con). Within each set of experiments, data are means ± SE of three independent experiments with at least three replicates for each. Bars with different letters denote significant difference at P < 0.05 according to Duncan’s multiple test
