Fig. 3From: Different photosynthetic responses of haploid and diploid Emiliania huxleyi (Prymnesiophyceae) to high light and ultraviolet radiationPigments content (A) and carotenoid-to-chl a ratio (B) of haploid (1N) and diploid (2N) Emiliania huxleyi acclimated to 100 µmol photons m−2 s−1 at 20 °C. Different letters in the superscript indicate significantly different means between different life-cycle phases (P < 0.05). Error bars denote standard deviations (n = 3)Back to article page
