Quantity of volatile organic compounds (ng g−1) whose production by Hamatocaulis vernicosus carpets was influenced by FR light addition (MTCC, B-cyclocitral) or exposure to Sphagnum VOC (MTCC under FR−). H. vernicosus shoots in the carpets were exposed only to VOCs released from neighbouring H. vernicosus individuals (control) or to VOCs released by surrounding H. vernicosus individuals and to VOC blend from S. flexuosum carpet (Sphagnum exposure), for more details see methods, Fig. S1 and Table S2. Both species were cultivated under artificial light conditions without FR light addition (FR−) or added FR light (FR+). VOCs were collected for 72 h. The error bars depict ± s.e. of means.
