Effect of paraquat on Fluorescence Parameters (Fv/Fm) in wheat leaves. Fv/Fm was quantitated before and after treatment with three different concentration of 0, 300 and 600 μM of paraquat. Paraquat treatment significantly decreased Fv/Fm only in stage C of development (P < 0.01) and had no significant effect in stage A and B.
