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

Figure 3

Effect of Fe³⁺ on the regeneration of planarian at different temperatures. (a) Contrast histogram of the number of days after regeneration of the head, trunk, and tail of the planarian at 15°C, under different treatment concentrations and water treatment; (b) similarly, at 20°C, contrast histogram of the number of days after the regeneration of the planarian; (c) similarly, the comparison histogram of the number of days of the regeneration of the planarian at 25°C. Note: indicates P < 0.001, indicates P < 0.01 with extremely significant difference, and indicates P < 0.05 with significant difference.
