The Effects of UV Radiation on Chloroplast Clumping and Photosynthesis in the Seagrass Halophila stipulacea Grown under High-PAR Conditions

Figure 5

Daily changes in electron transport rates (ETR) of plants grown on the water table for 14 days under control filters (open circles) or UV filters (closed circles), and PAR (400–700 nm) measured above the plants on the water table (full line) and UVR (300–400 nm) under the control filter (dotted line; there was no measurable UVR under the UV filter). Data points are means of 8 replicates ± SD.
