IMPROVED METHOD AND COMPOSITION FOR DETERMINING RESISTANCE TO AN ACETOHYDROXYACID SYNTHASE INHIBITOR

摘要

The invention describes a method for determining whether a plant is resistant to an acetohydroxyacid synthase ("AHAS") inhibitor. The method comprises: (a) treating a part taken from the plant with a acetohydroxyacid synthase inhibitor, a ketol-acid reductoisomerase inhibitor and an external supplement that is either a compound or combination of compounds selected from the group consisting of alanine, ammonium hydroxide, asparagine, and pyruvic acid or a salt thereof; and (b) measuring the amounts of acetohydroxybutyrate and/or acetolactate.
