Abstract: Engineering nanomaterials (ENMs) have garnered significant attention due to their unique structural and electrochemical properties. Their extensive application has demonstrated effectiveness in promoting plant growth, increasing crop yields, and enhancing seedling stress resistance. To comprehensively elucidate the mechanism underlying ENMs impact on plant growth and stress resilience, this review focuses on common ENMs (including carbon-based, metal-based, metal oxides, and quantum dots). We systematically summarize: the pathway for ENMs uptake by plants and their translocation within plant tissues; the effects of ENMs on plant developmental stages, tissue locations, and physiological processes; and the influence of ENMs application under different stress conditions (e.g., drought, salinity, heavy metal contamination), particularly the mechanisms underlying induced stress resistance. This review offers an in-depth analysis of the potential applications of ENMs in enhancing plant tolerance to abiotic stresses. By elucidating the mechanisms through which ENMs mitigate stress impacts, it advances understanding of the necessity and transformative potential as innovative tools in agricultural and forestry development, thereby offering valuable insights for future large-scale implementation.
