Description
Table 1 The chemical compounds found on pollen and ovulate (receptive and non-receptive) cones of Macrozamia miquelii (n is given for the total number of volatile samples and the number taken at midday as indicated). For each compound is given: its Kovat’ s retention index (RI), and its average % contribution to total emissions, the number of samples in which it was detected (N), and measurements of emission rate (ng min 1) within each cone type. In the average and minimum emission rate columns are the rates of all cone samples and, within parentheses, the rate for midday samples alone, if it changed. All maximum rates are from midday samples alone.
