From: Acclimation of intertidal macroalgae Ulva prolifera to UVB radiation: the important role of alternative oxidase

Fig. 3

Effects of ultraviolet-B (UVB) and photosynthetically active radiation (PAR) on photosystem II (PS II) inhibition parameters in Ulva prolifera on the 1st day and the 4th day. SHAM-1d and SHAM-4d show the changes of the SHAM group on the 1st day and the 4.th day, respectively. A The inhibition of PS II due to high PAR or PAR + UVB; B extra UVB-induced inhibition compared with PAR alone. All data are the mean values (± SD) from three biological replicates. Groups with different lowercase letters are significantly different (P < 0.05)
