Effects of Fe³⁺ on Acute Toxicity and Regeneration of Planarian (Dugesia japonica) at Different Temperatures

Figure 2

Effect of different temperatures and concentrations on the survival of planarian. (a-b) At 15°C, after treatment with different Fe³⁺ concentrations, the variation trend of the worm mortality was changed with time; (b) shows the change of mortality corresponding to each concentration; (c-d) similarly, it shows the distribution of the change in the mortality of the planarian after treatment at different concentrations of Fe³⁺ at 20°C; (e-f) changes in the mortality of the worms at different treatment concentrations at 25°C. Note: indicates P < 0.001, indicates P < 0.01 with extremely significant difference, and indicates P < 0.05 with significant difference.
