Fig. 9. Mean emission rates of major volatile components (±1 s.e., but not shown for those with very low emission rates) of four Macrozamia miquelii pollen cones. These were sampled in the field for 30 min over six days during pollination for both AM (morning sample start time, ~09:30 h) and midday samples (sample time started from ~11:30–13:30 h). The mean % contribution of these compounds to total emissions is reported above the bar graph of each cone and sample time. a) Emission rates of three monoterpenes, α-terpinene, α-pinene and limonene, which varied by> 5000 fold across cones (within the same sampling period). b) Emission rates of 2-methylbut-3-en-2-ol (MBO), and an aliphatic ester, prenyl crotonate, with a five-fold difference or less across cones (within the same sampling period).
