Figure 1.

Diurnal measurements of A, g_s, and W_i measured under square wave regimes of light. FLH (red), SNH (green), and SQH (blue) high-light treatments (full lines) were measured under SQ_High. FLL (red), SNL (green), and SQL (blue) low-light treatments (dashed lines) were measured under SQ_Low. Error bars represent mean ± se, n = 5–7. Gray shaded areas indicate when light source is off. Represented are examples of FLH (D), SNH (E), and SQH (F) to highlight fit of the temporal response exponential model (black line). Pink shaded areas illustrate growth light regimes for FLH (D), SNH (E), and SQH (F).
