The effects of plant treatment with H 2 O 2 or both H 2 O 2 and catalase on flowering and related responses. Water and aqueous solutions of the indicated compounds were used separately to immerse seeds of the indicated 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, H2O2 concentrations were measured by spectrometry (a), and the expression of FD and AP1 at the shoot apex was analyzed by real-time RT-PCR using the EF1α as a reference gene (b). Flowering time was scored (c), and plants were photographed after four weeks of growth (d). Quantitative data shown are average values ± standard deviations based on three experimental repeats each containing 50 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).
