Profiles of induced volatile organic compounds emitted from S. saman leaves. S. saman plants were treated either with water as a control (A), JA at 500 μm (B), or (−)-LCF at 500 μm (C). Headspace volatiles were collected for 24 h after initiation of treatment. Compounds were separated by gas chromatography and identified by mass spectrometry: 1, Eucalyptol; 2, β-ocimene; 3, unknown; 4, linalool; 5, DMNT; 6, C₁₀H₁₄; 7, unknown; 8, contamination; 9, methyl salicylate; 10, 3-hexenyl-iso-valerate; 11, β-caryophyllene; 12, 4,8,12-trimethyltrideca-1,3,7,11-tetraene; 13, methyl jasmonate; IS, internal standard (1-bromodecane). All experiments have been conducted at least four times with similar results.
