Photoperiod influences the timing of several growth processes in higher plants and macroalgae. Results from our experiments indicate photoperiodic control of germination and/or growth of diatom resting spores. We suggest that the onset of phytoplankton blooms m northerly areas, and possibly also further south, may be photoperiod dependent and linked to entrainment of phytoplankton resting spores from bottom sediments KEY WORDSPhytoplankton .
