Table 1.
Predicted values of floral terpene emission rates (μg g DW-1h-1) of the various species at the mean maximum temperature of the month of their flowering peaks (Tpeak) and at temperatures of 1, 2, 3, 4 and 5 °C higher than Tpeak. The values were predicted from the loess functions that fitted the measurements of floral terpene emissions at different temperatures.
