Score plots of orthogonal projections to latent structures discriminant analysis (OPLS-DA) of metabolomic and ionomic data. Metabolite data obtained from GC-MS of the acorns in July (a, R2Y [1] = 0.93, Q2 [1] = 0.45, CV-ANOVA p = 0.049), August (b, R2Y [1] = 0.74, Q2 [1] = 0.62, CV-ANOVA p = 0.018), and September (c, R2Y [1] = 0.85, Q2 [1] = 0.50, CV-ANOVA p = 0.005), and ionomic data obtained from element analysis and ICP-OES of acorns in September (d, R2Y [1] = 0.35, Q2 [1] = 0.64, CV-ANOVA p = 0.000) growing on two experimental sites with P-rich (squares) and P-deficient (triangles) content in soil
