【摘要】 本文对稗草对二氯喹啉酸的抗性方法进行了研究,结果表明小杯法、等浓度效果法和茎叶喷雾法和琼脂法都可以来鉴定稗草对二氯喹啉酸的抗性,其中琼脂法相关性高、试验条件一致性好、重复性好和操作简便,是一种快速的鉴定方法。琼脂法以芽长为指示参数选取发芽刚露白的稗种在27℃温度下培养72h。更多还原

【Abstract】 The methods for detection of quinclorac resistance in barnyardgrass were described in this paper.The results showed that the resistance of the barnyardgrass to quinclorac could be de-tected with the same dose quinclorac against barnyardgrass method,with spraying the stems method,with agar method and with litter cup method.The agar method was a more rapid and convenient method to determine quinclorac resistance in bamyardgrass,bud was cultured at27℃for72h and bud length was adopted as indicative parameter in this method.更多还原
