H₂O₂ or SNP treatment repressed the effect of BL on the inhibition of ABA-induced stomatal closure. (A) H₂O₂ (100 μM) or (B) SNP (100 μM) was applied 30 min after BL (1 μM) to the ABA-containing solution, and the cotyledons were incubated for a further 1 h before apertures were measured. Experiments were independently repeated twice (n=30 each time). Error bars indicate standard errors. Values labeled with different letters are statistically different analysed by one-way ANOVA (P<0.05). (This figure is available in color at JXB online.)
