The objective of this experiment was to evaluate the effects of grafting, zinc oxide nanoparticles (ZnO NPs), and their interaction on the nutritional composition of bell pepper plants. The treatments evaluated included grafted and non-grafted pepper plants with four concentrations of ZnO NPs (0, 10, 20, 30 mg L) applied to the foliage. The following parameters were evaluated: content of N, P, K, Ca, Mg, Mn, Zn, Fe, Cu, total antioxidants, ascorbic acid, total phenols, glutathione, total proteins, fruit firmness, and total soluble solids. Grafting increased the content of N 12.2%, P 15.9%, K 26.7%, Mg 20.3%, Mn 34.7%, Zn 19.5%, Fe 18.2%, Cu 11.5%, antioxidant capacity 2.44%, ascorbic acid 4.63%, total phenols 1.33%, glutathione 7.18%, total proteins 1.08%, fruit firmness 8.8%. The application of 30 mg L ZnO NPs increased the content of N 12.3%, P 25.9%, Mg 36.8%, Mn 42.2%, Zn 27%, Fe 45%, antioxidant activity 13.95%, ascorbic acid 26.77%, total phenols 10.93%, glutathione 11.46%, total proteins 11.01%, and fruit firmness 17.7% compared to the control. The results obtained demonstrate the influence of the use of grafts and ZnO NPs as tools that could improve the quality and nutrient content in fruits of bell pepper crops.
本实验的目的是评估嫁接、氧化锌纳米颗粒（ZnO NPs）及其相互作用对甜椒植株营养成分的影响。所评估的处理包括嫁接和未嫁接的辣椒植株，对其叶面施加四种浓度的ZnO NPs（0、10、20、30 mg/L）。评估了以下参数：氮、磷、钾、钙、镁、锰、锌、铁、铜的含量、总抗氧化剂、抗坏血酸、总酚、谷胱甘肽、总蛋白、果实硬度和总可溶性固形物。嫁接使氮含量增加了12.2%、磷增加了15.9%、钾增加了26.7%、镁增加了20.3%、锰增加了34.7%、锌增加了19.5%、铁增加了18.2%、铜增加了11.5%、抗氧化能力增加了2.44%、抗坏血酸增加了4.63%、总酚增加了1.33%、谷胱甘肽增加了7.18%、总蛋白增加了1.08%、果实硬度增加了8.8%。与对照相比，施加30 mg/L ZnO NPs使氮含量增加了12.3%、磷增加了25.9%、镁增加了36.8%、锰增加了42.2%、锌增加了27%、铁增加了45%、抗氧化活性增加了13.95%、抗坏血酸增加了26.77%、总酚增加了10.93%、谷胱甘肽增加了11.46%、总蛋白增加了11.01%、果实硬度增加了17.7%。所得结果证明了使用嫁接和ZnO NPs作为可以提高甜椒作物果实品质和营养含量的工具的影响。
