Fig. 1From: A comparative study of the photosynthetic capacity in two green tide macroalgae using chlorophyll fluorescenceMean optimal photochemical efficiency of photosynthesis (Fv/Fm) of U. prolifera and U. intestinalis, obtained from 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
