From: Different photosynthetic responses of haploid and diploid Emiliania huxleyi (Prymnesiophyceae) to high light and ultraviolet radiation

Fig. 5

A Maximum quantum yield of haploid (1N) and diploid (2N) Emiliania huxleyi after acclimation to growth light or 1 h of acute exposure to PAR or PAR + UVR. B Relative inhibition of Fv/Fm induced by PAR or PAR + UVR. The growth light, PAR and UVR were 20.8 W m−2 (100 µmol photons m−2 s−1), 83.3 W m−2 (400 µmol photons m−2 s−1) and 19.0 W m−2, respectively. Error bars denote standard deviations (n = 3). Different letters represent significantly different means between different life-cycle phases and different radiation treatments (P < 0.05)
