Photosynthetic performance of <i>Symbiodinium</i> under defined broadband spectra simulating <i>in situ</i> coral tissue and halogen lamp spectral composition.

The photosynthetic parameters Pmax (in O2 h−1 107 cells−1) or ETRmax, α, and Ek (in µmol photons m−2 s−1) were derived from O2 evolution based (PG) and Chl a fluoremetry-based (rETR and ETR) photosynthesis irradiance curves. A significant difference (p<0.05) between coral tissue and halogen lamp is denoted with an asterisk. Means (± SE) are shown (n = 3).
