Additional file 2. Volatile organic compounds collected in the headspace of Brassica rapa. Volatile organic compounds (VOCs) collected from the headspace of Brassica rapa (BR) (for details on the method see Bruinsma et al. [16]). The ratio of the peak areas in the gas chromatogram was calculated of VOCs collected from an empty receiver cylinder exposed to two flowering plants in the emitter cylinder (BR) and from an empty receiver cylinder when the emitter cylinder was left empty (BG). VOCs with a ratio of ≤ 0.8 (not grey) in a sample were determined by total ion composition (TIC) and retention index (RI). The sample number is indicated when the identity of a VOC was confirmed (conf.). VOCs with a BG/BR ratio ≤ 0.8, which were confirmed at least in one sample, are marked yellow. Confirmed VOCs by TIC in the B. rapa samples were additionally confirmed by squaring RI with literature and their peak areas in the gas chromatogram are presented by BR and BG in Additional file 3.
