采用盆栽及生物化学分析方法研究了安全剂NA对玉米的保护作用及对氟磺胺草醚的解毒效应。实验结果表明，安全剂NA对氟磺胺草醚残留的玉米具有明显的保护作用，不同玉米品种的保护作用有一定差异，其中，NA对自交系Lx347保护作用最好，自交系P138次之，杂交种东农0701B最差。在安全剂NA稀释倍数为200时，玉米谷胱甘肽（GSH）和谷胱甘肽-S-转移酶（GST）比活力增长量最多，且对叶部的增加作用最为明显。
英文摘要:
Potted plants and biochemical analysis method were conducted to study the safener NA protection on maize and detoxication on fomesafen injury . The results showed that the safener NA had a significant protection on maize caused by fomesafen residual, different varieties of maize had different protections. Among them, NA had the best protection on maize inbred lines Lx347, second was the maize inbred lines P138, and the maize hybrid 0701B was the worst. When safener NA has diluted by 200 times, the glutathione(GSH) content and glutathione-S-transferases(GST) activity reached the highest increment, and the leaves were the most obvious role in promoting.
