Photosynthetic acchmation of Ulva ngida and U rotundata arranged in canopies was assessed by conlblning laboratory and field experiments Changes in the light f ~ e l d caused by the selfshading of Ulva thalh resulted in an instantaneous effect on the photosynthetic parameters Photosynthetic efflclency decreased from the top of the canopy to the bottom as the photosynthetic active radiation/photosynthetic usable radiation ratio (PAR/PUR) increased In contrast, the hght compensation point showed… CONTINUE READING
