Figure 6. An example for the responses of the leaf photosynthetic rate (A) and stomatal conductance (g_s) to flecked irradiance illustrated in Fig. 5.

The red arrow indicate the start of first saturating light, the blue arrows indicate the data points whose instantaneous A and g_s reach 50% of the maximum A and g_s, and the green arrow indicate the data points whose instantaneous A and g_s reach 90% of the maximum A and g_s. Times to 50% of the maximum A (T_50%A) and the maximum g_s (T_50%gs) were identified as the times elapsed between the red arrows and the blue arrows, and times to 90% of the maximum A (T_90%A) and the maximum g_s (T_90%gs) were identified as the times elapsed between the red arrows and the green arrows.
