Tomato ( L.) is one of the most valuable horticulture crops, consumed in both its raw and processed forms. To increase yield and efficiency, conventional and organic fertilizers are utilized in modern agriculture. Traditional fertilizers increase crop yield but are harmful to the environment. These circumstances motivate the pursuit of an alternate solution. The purpose of this research was to investigate how the application of nanoparticles (nano-ZnO) combined with conventional fertilizer influence tomato plants' development, including the antioxidant potential of cultivated plants. Three factors such as different types of cultivars, dosage of applied nano-ZnO solution and the method of nanoparticles application were implemented. Multiple analysis of selected antioxidants content and their activities such as malondialdehyde (MDA), flavonoids, polyphenols, ascorbic acid, peroxidase (POX), superoxide dismutase (SOD) or catalase (CAT) were analyzed. The obtained data exhibited that all examined parameters were strongly dependent on three implemented factors: concentration of nano-ZnO suspension, the type of cultivated tomato and the method of nanoparticles application. For instance, the accumulation of MDA in cultivated plants was different among plants under nanoparticles treatment, but in one specific case (Malinowy Bossman cultivar treated with 50 mg/L nano-ZnO suspension) the content of this marker was decreased by 34% in comparison to the corresponding control. Nevertheless, the results presented in this study showed that the usage of certain doses of nano-ZnO suspension may increase the antioxidant potential of tomato plants.
番茄（L.）是最有价值的园艺作物之一，既可以生食也可以加工食用。为了提高产量和效率，现代农业中既使用传统肥料也使用有机肥料。传统肥料虽然能提高作物产量，但对环境有害。这些情况促使人们寻求替代解决方案。本研究旨在研究纳米氧化锌（nano-ZnO）与传统肥料结合应用如何影响番茄植物的生长，包括栽培植物的抗氧化潜力。实施了三个因素，即不同类型的品种、应用的纳米 ZnO 溶液的剂量和纳米颗粒应用的方法。对选定抗氧化剂的含量及其活性，如丙二醛（MDA）、类黄酮、多酚、抗坏血酸、过氧化物酶（POX）、超氧化物歧化酶（SOD）或过氧化氢酶（CAT）进行了多方面分析。所得数据表明，所有检查的参数都强烈依赖于三个实施因素：纳米 ZnO 悬浮液的浓度、栽培番茄的类型和纳米颗粒的应用方法。例如，在纳米颗粒处理下，不同品种的植物中 MDA 的积累不同，但在一个特定的情况下（用 50mg/L 纳米 ZnO 悬浮液处理的 Malinowy Bossman 品种），与相应的对照相比，这种标记物的含量减少了 34%。然而，本研究的结果表明，使用一定剂量的纳米 ZnO 悬浮液可能会提高番茄植物的抗氧化潜力。
