Nanomaterials containing zinc oxide are increasingly used in various industries, and in agriculture. Literature data confirm that zinc oxide nanoparticles can have a beneficial effect on germination, plant growth, photosynthesis and selected metabolic processes in various plant species. The use of zinc oxide nanoparticles can help to improve the yield of plants, but it is necessary to adjust the dose of this nanofertilizer to the stage of development and the plant species. Zinc oxide nanoparticles (ZnONPs) releases zinc ions, thus contributing to better nutrition of plants with this ingredient and may reduce soil pollution caused by excessive use of fertilizers. The use of zinc oxide nanoparticles may also be associated with toxicological risks for plants. Toxicity caused by ZnONPs may be manifested by reduced germination capacity, inhibition of growth, impaired cell division, abnormal gene expression, and symptoms of oxidative stress. The nanotoxicity of zinc oxide depends on the size of the nanoparticles, the dose and the plant species.
