Fig. 3From: A comparative study of the photosynthetic capacity in two green tide macroalgae using chlorophyll fluorescenceMean maximum relative electron transport rate (rETRmax) obtained from fitted rapid light response curves (RLCs) of U. prolifera and U. intestinalis, measured in situ and 7 days’ acclimation to each. Values are mean ± SD (n = 5). Different letters above bars indicate significantly different values (post hoc, p < 0.05)Back to article page
