摘要
目的:研究化学农药阿维菌素对枸杞多糖(LBP)含量的影响。方法:在枸杞瘿螨发生期,喷施2%阿维菌素乳油,定期采样。采用苯酚-硫酸法提取,分光光度法测定LBP含量。结果:枸杞喷药样品在施药后05 d,LBP含量随时间推移逐渐升高,5 d达到最高;药后10 d,LBP含量降到最低;药后21 d,LBP含量接近对照。喷药样品的LBP含量高于对照。结论:阿维菌素对枸杞多糖含量有一定影响。
Objective:To study the effect of abamectin on the content of Lycium barbarum polysaccharide(LBP).Methods:The Lycium barbarum plant was sprayed by 2% abamectin EC,while they were endangered by Aceria macrodonis Keifer.Then the samples of Lycium barbarum were picked periodically.LBP was extracted by phenol-sulfuric acid method and its content was measured by spectrophotometry method.Results:The content of LBP increased in the 05 days after pesticide application and reached the peak at the 5th day;10 days later,the content reduced to the minimum.It was close to the control sample after 21 days.LBP Content in samples were obviously higher than that of the control.Conclusion:Abamectin has some effects on the content of LBP.
