Table 1 shows the mean rate of transpiration from the leaves of a mock orange (Philadelphus) shrub at different air temperatures.
| Temperature (∘C^\circ\text{C}∘C) | Mean rate of transpiration (g dm−2 h−1\text{g}\,\text{dm}^{-2}\,\text{h}^{-1}gdm−2h−1) |
|---|---|
| 15 | 0.4 |
| 20 | 1.2 |
| 25 | 2.8 |
| 30 | 4.5 |
| 35 | 5.2 |
