The application of metallic nanoparticles improves the yield and content of bioactive compounds in plants. The aim of the present study was to determine the effects of the foliar application of copper nanoparticles (CuO-NPs) in the yield and content of bioactive compounds in lettuce. Different concentrations of CuO-NPs (0, 0.5, 1, 2, 4, and 6 mg mL) were applied in lettuce. The yield, nutraceutical quality, and enzymatic activity were determined. Foliar spraying of CuO-NPs induced an increase in the biosynthesis of bioactive compounds. In addition to an increase in the activity of the enzymes superoxide dismutase (SOD) and catalase (CAT) in lettuce plants, there were no negative effects on yield. Therefore, with the application of CuO-NPs, better quality lettuces are produced for the human diet due to the higher production of bioactive compounds.
金属纳米颗粒的应用提高了植物中生物活性化合物的产量和含量。本研究的目的是确定叶面喷施铜纳米颗粒（CuO-NPs）对生菜产量和生物活性化合物含量的影响。在生菜中施用不同浓度的CuO-NPs（0、0.5、1、2、4和6毫克/毫升）。测定了产量、营养品质和酶活性。叶面喷施CuO-NPs可诱导生物活性化合物生物合成增加。除了生菜植株中超氧化物歧化酶（SOD）和过氧化氢酶（CAT）的活性增加外，对产量没有负面影响。因此，通过施用CuO-NPs，由于生物活性化合物产量更高，可为人类饮食生产出品质更好的生菜。
