Correlation of the relative amounts of volatiles with the damage levels of mechanical wounding in lima bean leaves. The relative amount of the volatiles was determined by the ratio of the peak area of the particular compound (A_VOC) to the peak area of the internal standard (A_IS). The damage levels have been determined with 0 (no treatment), 0.33 (2.9 h, 313 mm²), 1.80 (6.85 h, 733 mm²; 16 h, 313 mm²), and 4.52 (17 h, 733 mm²), respectively. A, Octen-3-ol (○) and Hex-Ac (•). B, Ocimene (▪), C₁₀H₁₆O (•), linalool (○), and C₁₀H₁₄ (▴). C, DMNT (▴), MeSA (•), and TMTT (▪). MeSA and TMTT did not show linear correlations. The results are the mean ± sd (n = 5–10).
