The effects of plant treatment with H 2 O 2 on flowering and related responses. Aqueous solutions of H2O2 at the indicated concentrations were used separately to immerse seeds of wild-type plants and treat seven-day-old plants grown on a medium by adding every H2O2 solution into the medium in correspondingly labeled bottles. Two days later, FD and AP1 expression at the shoot apex was analyzed by Northern blotting analyses using EF1α gene as a reference (a); H2O2 concentrations were measured by spectrometry (b). Subsequently, flowering time (c) and rosette leaf number (d) were scored. Quantitative data shown are average values ± standard deviations based on three experimental repeats each containing 30 plants. On bar graphs, different letters in regular and italic fonts indicate significant differences by analysis of variance using Fisher’s least significant difference test and Tukey-Kramer’s test, respectively (n = 3; P < 0.01).
