 Title    Two Sites of Inhibition of the Photosynthetic Electron Transport Chain by the Herbicide Trifluralin  
 Abstract    The effect o f trifluralin on the photosynthetic electron transport has been investigated by oxygen evolution and thermoluminescence m easurem ents. The results confirm the earlier observations that trifluralin at low concentrations blocks electron transport between the two photosystems probably at the same site as DBMIB does. A t higher concentrations however, trifluralin inhibits the reaction from H aO -*■ /?BQ also and affects the thermoluminescence of chloroplasts in a manner sim ilar to DCM U. These results suggest that trifluralin has a second inhibitory site therefore the use o f trifluralin as a specific inhibitor o f electron transport has to be questioned.
