Rates of stomatal movements in response to blueless PAR in younger and older plants
| Younger plants | Older plants | ||
| CO2 air concentration (μmol CO2 mol−1) | 400 | 400 | 400 |
| Parameter (% s−1) | kc | ko | kc |
| Mean value | 0.33 | 0.10 | 0.24 |
| SD | 0.06 | 0.01 | 0.06 |
Values were calculated after fitting of two non-linear functions (cf. statistical analysis). kc represents the rate of stomatal closure and ko the rate of stomatal opening. Mean values are shown ±SD. n=5 for each set of plants.
