Columns with the same letter are not significantly different a The ‘‘Rank’’ column gives a value according to the abundance of each compound: the lower the value the more abundant the metabolite.
b For flower stage 1 (FA) all TIC areas are given expressed in arbitrary units. Injections of 1 LL of a 50 mg/mL DCM extract of fresh tissue was used in all samples. c All other flower stages (FB and FC) and all leaf stages (LA to LD) are expressed as percentages relative to FA.
d Polygodial contains a fraction of 9- epi -polygodial, which cannot be estimated reliably by GC–MS.
e b- Elemene is the heat-induced Cope rearrangement product formed from germacrene A in the GC–MS injection path (De Kraker et al., 1998).
f Alkane.
g Carotenoid derivative.
h Fatty acid derivative.
i Significant differences between tissues based on overall contents by paired t -test. Tissue LD was only done in duplicate and therefore not part of the analysis.
