Abstract
In order to determine resisitance level of Beckmannia syzigachne populations in primary rape planting areas in Hunan Province,bioassay method was employed to determine resistance level of Beckmannia syzigachne to Quizalofop-P,and activity of GST were determined.The results showed that relative resistance ratio of Yongan population was 23.60,indicating medium resistance level.Relative resistance ratio of other populations were between 2.48~8.53,indicating low resistance level.GST activity of resistant Beckmannia syzigachne population was significantly higher than sensitive Beckmannia syzigachne population,indicating it would be possible mechanism of resistance to Quizalofop-P.关键词
