Growth curves underamFL after the addition of 1 min of bright light (800 μmol photons m^− 2 s^− 1) to every 5 min of low light (80 μmol photons m^− 2 s^− 1) andbsFL after the addition of 1 min of stronger light (2000 μmol photons m^− 2 s^− 1) to every 5 min of low light (20 μmol photons m^− 2 s^− 1)。Culture experiments were repeated three times. The values shown are the means of three biological replicates
