Nanotechnology represents an opportunity to improve the use of elements in agriculture. Selenium is an element that is beneficial to plants and essential to the human diet. The size of nanoparticles gives them characteristics that can enhance the benefits that selenium provides to plants. The objective of the present study was to determine the effects of selenium nanoparticles on the growth, antioxidant responses, and fruit quality of tomato developed under NaCl stress. Four doses of selenium nanoparticles (1, 5, 10, and 20 mg L) under NaCl stress, only NaCl, and a control were evaluated. The results showed that the impact of salinity on the growth of the tomato crop can be reduced with the application of selenium nanoparticles. However, the amount of both enzymatic and non-enzymatic compounds significantly increased in the leaves and fruits of tomato. The results suggest that the application of selenium nanoparticles generated a positive effect against salinity in the tomato crop; moreover, it had a positive impact on the content of beneficial biocompounds for human health in tomato fruits.
纳米技术代表着提高农业中元素利用效率的机会。硒是一种对植物有益且对人类饮食至关重要的元素。纳米颗粒的大小赋予了它们一些特性，可以增强硒对植物的益处。本研究的目的是确定硒纳米颗粒对在 NaCl 胁迫下生长的番茄的生长、抗氧化响应和果实品质的影响。在 NaCl 胁迫下，评估了 4 种硒纳米颗粒剂量（1、5、10 和 20mg/L）、仅 NaCl 和对照。结果表明，应用硒纳米颗粒可以减轻盐度对番茄作物生长的影响。然而，番茄叶片和果实中酶和非酶化合物的含量都显著增加。研究结果表明，应用硒纳米颗粒对番茄作物的盐胁迫产生了积极的影响，同时对番茄果实中对人体健康有益的生物化合物含量也产生了积极的影响。
