Testing of the two-cylinder experiment - Peak areas of volatile organic compounds collected from an empty receiver cylinder exposed to odors of two flowering Brassica rapa and from an empty (emitter) cylinder. Peak areas of volatile organic compounds collected from an empty receiver cylinder exposed to odors of two flowering Brassica rapa (yellow) and from an empty (emitter) cylinder (background, grey), which showed a ratio of the peak areas for background/B. rapa ≤ 0.8 and which identity was confirmed by squaring the retention index with literature. Values of peak area (median, 1st and 3rd quartiles, SD) obtained from total ion chromatogram. DF = 8 unless in c) DF = 7 as one B. rapa sample was excluded as outlier. P-values are based on an ANOVA at α = 0.05. Panel a) and e) present significantly higher amounts of volatiles in the B. rapa than in the background sample.
