Figure 5.
Chemical dissection of volatiles released by different parts of the sporophyte (insert). Total ion chromatograms are shown from (A) freely extruded spores, (B) dissected capsule and (C) the remaining hypophysis. The horizontal axis is time (and GC oven temperature, increasing from 60 °C to 240 °C at 10 °C min−1. The vertical axis is signal intensity (detector voltage) – note that the vertical scales are not the same for the strongly scented hypophysis and the more weakly scented spores. Pie charts indicate relative contributions of different compound classes to total emissions (see legend), and are scaled to total GC-MS peak areas – note that capsules and especially spores are dominated by saturated long-chain hydrocarbons.
