Tomato ( L.), as one of the most valuable horticulture crops, was chosen to investigate the effect of nanoparticles (NPs) in the form of nano-ZnO combined with conventional fertilizer on the quality of tomato fruits, including their antioxidant potential (total antioxidant activity, lycopene and β-carotene content), sugars content and allergenic potential (profilin and Bet v 1 content). Nano-ZnO was implemented during plant cultivation, applied by foliar spraying or directly via soil, at three different concentrations (50, 150 and 250 mg/L). The obtained results suggest that the usage of NPs during tomato plant cultivation had minor impacts on parameters such as total antioxidant activity or the content of selected allergens. Even though the total antioxidant activity was not affected by nano-ZnO, the malondialdehyde activity (MDA) content was notably decreased in fruits under nano-ZnO treatment. The content of lycopene and β-carotene was significantly affected by the use of nano-ZnO. Moreover, the usage of nano-ZnO significantly increased the total sugar content in fruits treated with nanoparticles via foliar spraying. Based on the obtained results, it can be stated that nano-ZnO, regardless of the method of application, significantly affected tomato fruits which can be beneficial for fruit production.
番茄（L.）作为最有价值的园艺作物之一，被选择来研究纳米氧化锌（nano-ZnO）与常规肥料结合的纳米粒子（NPs）对番茄果实品质的影响，包括其抗氧化潜力（总抗氧化活性、番茄红素和β-胡萝卜素含量）、糖含量和致敏性（丝氨酸蛋白酶抑制剂和 Bet v 1 含量）。纳米 ZnO 在植物生长期间通过叶面喷施或直接通过土壤以三种不同浓度（50、150 和 250mg/L）进行应用。研究结果表明，在番茄植株生长过程中使用 NPs 对总抗氧化活性或所选过敏原的含量等参数的影响较小。尽管纳米 ZnO 对总抗氧化活性没有影响，但纳米 ZnO 处理下果实中的丙二醛（MDA）含量显著降低。番茄红素和β-胡萝卜素的含量明显受到纳米 ZnO 的影响。此外，纳米 ZnO 的使用通过叶面喷施显著增加了纳米粒子处理的果实中的总糖含量。基于获得的结果，可以说纳米 ZnO 无论应用方式如何，都显著影响了番茄果实，这对果实生产是有益的。
