Figure 5. The changes of photosynthesis rate (A), stomata conductance (B), and transpiration rate (C) in each treatment (PAR = 1,000 μmol m⁻² s⁻¹).

The ambient CO2 concentration (400 ppm) was used during the measurement. Vertical lines represent the standard error (n = 3) and values for the same date with the same letter are not significantly different at a 5% significance level.
