Abstract
Pollen germination was tested in six Phalaris minor populations in a germination medium consisting of raffinose (7.5%) + boric acid (20 ppm) + calcium chloride (300ppm) supplemented with 0.1–2000 µM of fenoxaprop-p-ethyl, clodinafop-propargyl and pinoxaden. The populations were also tested in a pot culture assay. A parallel response was observed with regard to the level of resistance in the two systems. The method showed the possibility of a rapid screening test for resistant populations.
