Global Metabolite Comparison at 100% Hydrated and at 60% RWC between S. stapfianus and S. pyramidalis.
PLS-DA model is constructed from 105 variables (i.e., metabolites) generating a three-PLS-DA component model with R2 = 65.2, and Q2 = 61.0. S. pyramidalis: squares, 100% hydrated; crosses, 60% RWC. S. stapfianus: asterisks, 100% hydrated; upside down triangles, 60% RWC.
