In agriculture, abiotic stress is one of the critical issues impacting the crop productivity and yield. Such stress factors lead to the generation of reactive oxygen species, membrane damage, and other plant metabolic activities. To neutralize the harmful effects of abiotic stress, several strategies have been employed that include the utilization of nanomaterials. Nanomaterials are now gaining attention worldwide to protect plant growth against abiotic stresses such as drought, salinity, heavy metals, extreme temperatures, flooding, etc. However, their behavior is significantly impacted by the dose in which they are being used in agriculture. Furthermore, the action of nanomaterials in plants under various stresses still require understanding. Hence, with this background, the present review envisages to highlight beneficial role of nanomaterials in plants, their mode of action, and their mechanism in overcoming various abiotic stresses. It also emphasizes upon antioxidant activities of different nanomaterials and their dose-dependent variability in plants' growth under stress. Nevertheless, limitations of using nanomaterials in agriculture are also presented in this review.
在农业中，非生物胁迫是影响作物生产力和产量的关键问题之一。此类胁迫因素会导致活性氧的产生、膜损伤以及其他植物代谢活动。为了中和非生物胁迫的有害影响，人们采用了多种策略，其中包括利用纳米材料。纳米材料目前正在全球范围内受到关注，以保护植物生长免受干旱、盐度、重金属、极端温度、洪水等非生物胁迫的影响。然而，它们的行为受到农业中使用剂量的显著影响。此外，纳米材料在各种胁迫下对植物的作用仍有待了解。因此，在此背景下，本综述旨在突出纳米材料在植物中的有益作用、它们的作用方式以及克服各种非生物胁迫的机制。它还强调了不同纳米材料的抗氧化活性及其在胁迫下对植物生长的剂量依赖性变异性。尽管如此，本综述也介绍了在农业中使用纳米材料的局限性。
