The dark adapted cells of the green alga Spongiochloris sp. were exposed to "white light" of 1000 _mol(photon)m-2s-1 for 2 h and then dark adapted for 1.5 h. Changes of photochemical activities during photoadaptation were followed by measurement of chlorophyll (Chl) fluorescence kinetics, 77 K emission spectra, photosynthetic oxygen evolution, and pigment composition. We observed a build-up of slowly relaxing non-photochemical quenching which led to a decrease of the Fv/Fm parameter and the connectivity.
