Fig. 1From: Physiological responses and algae inhibition of Pontederia cordata to simulated eutrophication and acid rain co-pollutionThe interactive effects of simulated eutrophication and simulated acid rain (SAR) on the root activity (a), Chl T (b), SOD (c), CAT (d), REC (e), and MDA (f) of P. cordata harvested on day 28. Results are expressed as mean of triplicate samples ± standard error. Different lowercase letters indicate significant differences at P < 0.05Back to article page
