In today's time, agricultural productivity is severely affected by climate change and increasing pollution. Hence, several biotechnological approaches, including genetic and non-genetic strategies, have been developed and adapted to increase agricultural productivity. One of them is nano-priming, i.e., seed priming with nanomaterials. Thus far, nano-priming methods have been successfully used to mount desired physiological responses and productivity attributes in crops. In this review, the literature about the utility of nano-priming methods for increasing seed vigor, germination, photosynthetic output, biomass, early growth, and crop yield has been summarized. Moreover, the available knowledge about the use of nano-priming methods in modulating plant antioxidant defenses and hormonal networks, inducing salinity tolerance and disease resistance, as well as alleviating heavy metal toxicity in plants, is reviewed. The significance of nano-priming methods in the context of phytotoxicity and environmental safety has also been discussed. For future perspectives, knowledge gaps in the present literature are highlighted, and the need for optimization and validation of nano-priming methods and their plant physiological outcomes, from lab to field, is emphasized.
在当今时代，农业生产力受到气候变化和污染加剧的严重影响。因此，人们已经开发并采用了多种生物技术方法，包括遗传和非遗传策略，以提高农业生产力。其中之一是纳米引发，即用纳米材料对种子进行引发处理。到目前为止，纳米引发方法已成功用于引发作物所需的生理反应和生产力特性。在这篇综述中，总结了有关纳米引发方法在提高种子活力、发芽率、光合产量、生物量、早期生长和作物产量方面效用的文献。此外，还综述了关于使用纳米引发方法调节植物抗氧化防御和激素网络、诱导耐盐性和抗病性以及减轻植物重金属毒性的现有知识。还讨论了纳米引发方法在植物毒性和环境安全方面的重要性。对于未来展望，强调了当前文献中的知识空白，以及从实验室到田间对纳米引发方法及其植物生理结果进行优化和验证的必要性。
