| 摘 要： | 采用种子检测法,鉴定了对除草剂高效氟吡甲禾灵产生抗药性的看麦娘(Alopecu-rus aequalis Sobol.)生物型JXRII。为探讨看麦娘对高效氟吡甲禾灵产生抗性的生理反应,以敏感生物型JJSII为对比,喷施高效氟吡甲禾灵后,测定抗药生物型和敏感生物型几个重要生理指标变化情况的差异。结果表明:高效氟吡甲禾灵处理下,JJSII的叶片电解质泄漏率、MDA含量极显著上升,叶绿素、类胡萝卜素含量下降;JXRII叶片的电解质渗漏率、MDA含量、叶绿素、类胡萝卜素均与对照无显著差异;高效氟吡甲禾灵处理下,JJSII的GSH含量在处理后就开始逐渐下降,JXRII的GSH含量始终高于对照;二者可溶性糖含量均增加,敏感生物型JJSII可溶性糖含量增加的幅度远远大于抗性生物型JXRII;这2种群体经除草剂胁迫下,除草剂对敏感性生物型的生理变化影响大,抗性生物型表现为一定的生理适应性。 |

| Abstract: | Alopecurus aequalis is a troublesome weed in oilseed rape field,and herbicide haloxyfop-R-methyl is often used for its control.A rapid identification by the method of seed bioassay showed that A.aequalis biotype JXRII had the resistance to the herbicide,while biotype type JJSII was in adverse.In order to approach the differences in the physiological responses of the two biotypes to the herbicide,haloxyfop-R-methyl was sprayed on them,and some important physiological indices were determined.Two days after sp... |
