Effects of ultraviolet-B (UVB) and photosynthetically active radiation (PAR) on nicotinamide adenine dinucleotide phosphate hydrogen (NADPH) content 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. All data are the mean values (± SD) from three biological replicates. Groups with different lowercase letters are significantly different (P < 0.05)
