Heatmap of the metabolite profiles of leaves, lemmas and glumes at the anthesis (A) and grain filling (GF) stages under high-yielding (HY) and water stress (WS) conditions. p-values are shown for the organ (Po) and stage (Ps) factors and their interaction (Po*s). The red-blue color scale was obtained from Z-score transformation of actual values. Black indicates metabolites that were not detected. *, p < 0.05; **, p < 0.01; ***, p < 0.001.
