Effect of GST inhibitor, NBD-Cl, and S-metolachlor on seedling growth of Amaranthus palmeri in agar-based assays using a representative resistant [14CRI-G(A)] and susceptible [SS (B)] population. Root lengths were measured at 14 days of incubation in a growth chamber set at 30/28°C day/night temperature. The experiment was conducted twice. The upper and lower left panels of (A) and (B) are the non-treated and NBD-Cl treated checks of resistant and susceptible populations, respectively.
