Fig 1. Photosynthetic potential, light stress and non-photochemical quenching under constant high and low DLI, and under two variable DLI treatments.

Fig 1

Mean maximum quantum yield (Fv/Fm), excitation pressure on PSII (Qm) and non-photochemical quenching (NPQ) of Pachyseris speciosa (A, C, E)—and Acropora millepora (B, D, F), over the 20-days experiment in high DLI treatment (HL, orange), low DLI treatment (LL, purple), variable DLI 1 treatment (VL1, blue dashed lines) and variable DLI 2 treatment (VL2, green dashed lines). Values represent means over 16 colonies per treatment per species, with shaded areas representing standard error.
