Relative levels of selected metabolites in tomato pericarp from experiment 1, measured by LCMS. The fruits were treated with white light (500 μmol m⁻² s⁻¹; open symbols) or darkness (closed symbols) for 15 days and sampled at indicated days. Error bars indicate the least significant difference; letters (A–F) indicate significant differences between treatments or days at α = 0.01, n = 3 (three pools of two fruits each).
