Natural and experimental light fluctuations vs. stomatal conductances.

Obs. : typical irradiance in shade and sunfleck (W m−2); Obs. : typical sunfleck duration (s); Exp. : experimental range in irradiance (W m−2); Min. : observed minimum stomatal conductance (m s−2); Max. : observed maximum stomatal conductance (m s−1); : time to 90% of max. (s). Literature values of reported in units of mol m−2 s−1 were converted to m s−1 using Equation 19.1Sorghum sp., lower leaves.2Nothofagus cunninghamii, coppice leaves.3Nothofagus cunninghamii, upper canopy leaves.4Psychotria micrantha, canopy gaps.5Isertia haenkeana, clearings.6Triticum sp., Fig. 3.7Pteridium aquilinum.8Acer rubrum.
