Insufficient availability of water is a major global challenge that plants face and that can cause substantial losses in plant productivity and quality, followed by complete crop failure. Thus, it becomes imperative to improve crop cultivation/production in unsuitable agricultural fields and integrate modern agri-techniques and nanoparticles (NPs)-based approaches to extend appropriate aid to plants to handle adverse environmental variables. Nowadays, NPs are commonly used with biological systems because of their specific physicochemical characteristics, viz., size/dimension, density, and surface properties. The foliar/soil application of nanosilicon (nSi) has been shown to have a positive impact on plants through the regulation of physiological and biochemical responses and the synthesis of specific metabolites. Reactive oxygen species (ROS) are produced in plants in response to drought/water scarcity, which may enhance the ability for adaptation in plants/crops to withstand adverse surroundings. The functions of ROS influenced by nSi and water stress have been assessed widely. However, detailed information about their association with plants and stress is yet to be explored. Our review presents an update on recent developments regarding nSi and water stress in combination with ROS accumulation for sustainable agriculture and an eco-friendly environment.
水资源供应不足是植物面临的一项重大全球挑战，它会导致植物生产力和品质大幅下降，进而导致作物绝收。因此，改善不适宜农田的作物种植/生产，并整合现代农业技术和基于纳米颗粒（NPs）的方法，以向植物提供适当援助来应对不利环境变量，变得势在必行。如今，由于纳米颗粒具有特定的物理化学特性，即尺寸/维度、密度和表面性质，它们常用于生物系统。已表明，通过调节生理和生化反应以及特定代谢产物的合成，叶面/土壤施用纳米硅（nSi）对植物有积极影响。植物在应对干旱/缺水时会产生活性氧（ROS），这可能增强植物/作物适应不利环境的能力。纳米硅和水分胁迫对活性氧功能的影响已得到广泛评估。然而，关于它们与植物和胁迫之间关联的详细信息仍有待探索。我们的综述介绍了纳米硅与水分胁迫结合活性氧积累在可持续农业和生态友好环境方面的最新进展。
