Mean specific growth rates of <i>P. tricornutum</i>.

Mean specific growth rates of P. tricornutum cells grown under LC and HC conditions and both acclimated (for 25–36 generations) to the constant growth light levels in the present study compared to that observed in the previous study under fluctuating sunlight (acclimated for 21–25 generations) [12]. The data in parentheses represent the percentage change between the LC and HC conditions. Note, the µ values are much smaller under fluctuating than under the constant light regimes.
