PCA representing the whole set of data. 337 samples are here plotted in PCA by using all compounds as variables. A, Control unwounded leaves (C) are well-separated from damaged leaves. HW and MD show a clear separation. MDOS produced intermediate patterns between HW and MD. B, Loading plot highlights the discriminant variables (blue circle). Compound legend: a, n-hexanal; b, (E)-2-hexenal; c, (Z)-3-hexen-1-ol; d, 1-octen-3-ol; e, 6-methyl-5-hepten-2-one; f, octanal; g, (Z)-3-hexenyl acetate; h, p-cymene; i, limonene; j, 2-ethyl hexanol; k, (E)-β-ocimene; l, 1-octanol; m, linalool; n, nonanal; o, DMNT; p, (Z)-3-hexenyl butyrate; q, decanal; r, tridecane; s, geranyl acetone; t, (E)-nerolidol; u, TMTT.
