Fig 2. The nematode growth showed fluctuation in inhibition over generations from G1 to G4 in exposure to Cd, Cu, Pb and Zn.

Fig 2

The body length of nematodes in the control was 1.14 ± 0.11 mm, and the average value was normalized to 100% (dash line); *: significantly different from the concurrent control, p < 0.05; #: significantly from the earlier generation, p < 0.05; +: significantly different from the lower concentration, p < 0.05; Error bar: standard error.
