Table 1 Volatile floral terpenoids and their emission rates for greenhouse-grown plants (A-F) used for transcriptomics. Emission rates are given in μg per flower per hour. Volatile terpenoids are ordered by sub class (see Table S1) and retention time (min). The identity of all compounds except isophytol (*) and ocimene epoxide (*) was confirmed through co-chromatography and mass spectral comparison with synthetic standards
