Spatial response of F_v/F_m from tomato leaves grown under either 12 h lighting (200 µmol m⁻² s⁻¹ red + 50 µmol m⁻² s⁻¹ blue, 06:00–18:00) and CL (200 µmol m⁻² s⁻¹ red, 06:00–18:00 + 50 µmol m⁻² s⁻¹ blue, 18:00–06:00) at 22 DIT (A and B) and 50 DIT (C–F). Chlorophyll fluorescence images of the 5^th leaf are labelled (A–D) and images of the 10^th leaf are labelled (E and F).
