Zinc oxide nanoparticles (ZnO-NPs) can enhance zinc bioavailability in plants, improving crop nutritional quality and addressing global zinc deficiency. This study aimed to investigate the effects of zinc oxide nanoparticles (ZnO-NPs), obtained by a green synthesis method, on the growth, yield parameters, and zinc content of rice plants. In the study, two different application strategies of ZnO-NPs on rice plants were evaluated, i.e., foliar spray and seed priming. To compare the effects of these application strategies, rice plants were treated with ZnO-NPs at two different concentrations, 25 mg/L and 50 mg/L. Effects of ZnO-NPs on plant growth (shoot and root length, fresh and dry mass), chlorophyll and carotenoid content, grain yield and zinc content were investigated. The results showed that both ZnO-NP application methods increased rice growth and yield, especially the combined method (seed priming + foliar spray) provided the highest efficiency. It was observed that seed zinc content was increased up to 10% by seed priming method and foliar spray application increased the zinc content up to 23% while the combination of seed priming and foliar spray increased zinc content up to 122%. In general, applications at 50 mg/L concentration increased more than 25 mg/L. These results indicate that ZnO-NPs can be an effective tool for zinc deficiency management in agricultural practices and can improve the yield and nutritional content of staple foods such as rice.
氧化锌纳米颗粒（ZnO-NPs）可以提高植物对锌的生物利用率，改善作物营养品质，解决全球锌缺乏问题。本研究旨在探究通过绿色合成法获得的氧化锌纳米颗粒（ZnO-NPs）对水稻植株生长、产量参数和锌含量的影响。在该研究中，评估了ZnO-NPs在水稻植株上的两种不同施用策略，即叶面喷施和种子引发。为比较这些施用策略的效果，用两种不同浓度（25mg/L和50mg/L）的ZnO-NPs处理水稻植株。研究了ZnO-NPs对植株生长（地上生长（地上部和根部长度、鲜重和干重）、叶绿素和类胡萝卜素含量、籽粒产量和锌含量的影响。结果表明，两种ZnO-NP施用方法均提高了水稻的生长和产量，尤其是联合方法（种子引发+叶面喷施）效率最高。观察到，种子引发法使种子锌含量提高了10%，叶面喷施使锌含量提高了23%，而种子引发和叶面喷施相结合使锌含量提高了122%。总体而言，50mg/L浓度的施用效果比25mg/L的更好。这些结果表明，ZnO-NPs可以成为农业实践中管理锌缺乏的有效工具，并可以提高水稻等主食的产量和营养成分。
