The increasing use of nanofertilizers in modern agriculture and their impact on crop yield and pest management require further research. In this study, the effects of nano-Fe, -Zn, and -Cu (which are synthesized based on nanochelating technology), and urea (N) fertilizers on the antioxidant activities of wheat plants (cv. Chamran), and the wheat green aphid (Rondani) are investigated. The authors observed the highest levels of phenolics in non-infested nano-Zn-treated plants (26% higher compared with control). The highest HO levels are in the infested and non-infested nano-Zn-treated and infested nano-Fe-treated plants (in infested nano-Zn and nano-Fe treated plants, 18% and non-infested nano-Zn-treated plants, 28% higher compared with control). The highest peroxidase (POX) activity is observed in the infested and non-infested N-treated and non-infested water-treated plants (almost 14%, 37%, and 46% higher than control, respectively). The lowest activity is in the infested plants' nano-Zn and -Fe treatments (almost 7 and 5 folds lower compared to the control, respectively). The highest and lowest catalase (CAT) activity are in the infested N-treated plants (almost 42% higher than control) and water-treated plants, respectively. The infested nano-Zn, -Fe, -Cu and Hoagland-treated plants showed the highest superoxide dismutase (SOD) activity. Regarding the antioxidant enzyme activities of , the highest POX activity is in the nano-Cu treatment (more than two folds higher compared with control); the highest CAT and SOD activities are in the nano-Cu and -Zn treatments. It can be concluded that the application of nanofertilizers caused increasing effects on the wheat plant's antioxidant system and its resistance to .
纳米肥料在现代农业中的使用日益增加，及其对作物产量和害虫管理的影响需要进一步研究。在本研究中，研究了纳米铁、锌和铜（基于纳米螯合技术合成）以及尿素（氮）肥料对小麦植株（Chamran品种）和小麦绿蚜（Rondani）抗氧化活性的影响。作者观察到，未受侵染的纳米锌处理植株中酚类物质含量最高（比对照高26%）。过氧化氢水平最高的是受侵染和未受侵染的纳米锌处理植株以及受侵染的纳米铁处理植株（在受侵染的纳米锌和纳米铁处理植株中，分别比对照高18%，在未受侵染的纳米锌处理植株中，比对照高28%）。过氧化物酶（POX）活性最高的是受侵染和未受侵染的氮处理植株以及未受侵染的水处理植株（分别比对照高约14%、37%和46%）。活性最低的是受侵染植株的纳米锌和铁处理（分别比对照低约7倍和5倍）。过氧化氢酶（CAT）活性最高和最低的分别是受侵染的氮处理植株（比对照高约42%）和水处理植株。受侵染的纳米锌、铁、铜和霍格兰处理植株表现出最高的超氧化物歧化酶（SOD）活性。关于抗氧化酶活性，POX活性最高的是纳米铜处理（比对照高两倍多）；CAT和SOD活性最高的是纳米铜和锌处理。可以得出结论，纳米肥料的施用对小麦植株的抗氧化系统及其对……的抗性产生了增强作用。 （原文此处“its resistance to.”后面似乎缺失内容）
