Nanotechnology is attracting significant attention worldwide due to its applicability across various sectors. Titanium dioxide nanoparticles (TiO2NPs) are among the key nanoparticles (NPs) that have gained extensive practical use and can be synthesized through a wide range of physical, chemical, and green approaches. However, TiONPs have attracted a significant deal of interest due to the increasing demand for enhancing the endurance to abiotic stresses such as temperature stress. In this article, we discuss the effects of temperature stresses such as low (4 °C) and high temperatures (35 °C) on TiONPs. Due to climate change, low and high temperature stress impair plant growth and development. However, there are still many aspects of how plants respond to low and high temperature stress and how they influence plant growth under TiONPs treatments which are poorly understood. TiONPs can be utilized efficiently for plant growth and development, particularly under temperature stress, however the response varies according to type, size, shape, dose, exposure time, metal species, and other variables. It has been demonstrated that TiONPs are effective at enhancing the photosynthetic and antioxidant systems of plants under temperature stress. This analysis also identifies key knowledge gaps and possible future perspectives for the reliable application of TiONPs to plants under abiotic stress.
纳米技术因其在各个领域的适用性而在全球范围内受到广泛关注。二氧化钛纳米颗粒（TiO₂ NPs）是已获得广泛实际应用的关键纳米颗粒之一，可以通过多种物理、化学和绿色方法合成。然而，由于提高对非生物胁迫（如温度胁迫）耐受性的需求不断增加，TiO₂ NPs引起了极大的关注。在本文中，我们讨论了低温（4℃）和高温（35℃）等温度胁迫对TiO₂ NPs的影响。由于气候变化，低温和高温胁迫会损害植物的生长和发育。然而，关于植物如何应对低温和高温胁迫以及它们在TiO₂ NPs处理下如何影响植物生长，仍有许多方面了解甚少。TiO₂ NPs可有效地用于植物生长和发育，特别是在温度胁迫下，但其反应因类型、大小、形状、剂量、暴露时间、金属种类和其他变量而异。已经证明，TiO₂ NPs在温度胁迫下能有效增强植物的光合和抗氧化系统。该分析还确定了在非生物胁迫下将TiO₂ NPs可靠应用于植物的关键知识空白和可能的未来前景。
