More than 2 billion people worldwide suffer from micronutrient malnutrition, sometimes known as hidden hunger. Zn malnutrition affects around a third of the world's population. The physicochemical features of soil, which limit the availability of Zn to plants, cause Zn deficiency. The eating habits of certain populations are more depended on Zn-deficient staple foods. Due to the high expense and certain interventions such as diet diversification, zinc supplementation and food fortification cannot be achieved in disadvantaged populations. Biofortification is the most practical technique for alleviating Zn malnutrition. Seed priming with nutrients is a promising biofortification approach for edible crops. Seed nutripriming with zinc is a cost-effective and environmentally benign approach of biofortification. Seeds can be nutriprimed with Zn using a variety of methods such as Zn fertilisers, Zn chelated compounds and Zn nanoparticles. Nutripriming with nanoparticles is gaining popularity these days due to its numerous advantages and vast biofortification potential. Seeds enriched with Zn also aid plant performance in Zn-deficient soil. Zn an essential trace element can regulate physiological, biochemical and molecular processes of plant cells and thus can enhance germination, growth, yield and bioavailable Zn in edible crops. Moreover, zinc emerges as an important element of choice for the management of COVID-19 symptoms.

全世界有超过 20 亿人患有微量营养素营养不良，有时被称为隐性饥饿。锌营养不良影响着世界约三分之一的人口。土壤的物理化学特性限制了植物对锌的利用，导致缺锌。某些人群的饮食习惯更多地依赖于缺锌的主食。由于高昂的费用和某些干预措施（例如饮食多样化、锌补充剂和食品强化）无法在弱势群体中实现。生物强化是缓解锌营养不良最实用的技术。用营养物引发种子是一种有前途的可食用作物生物强化方法。用锌进行种子营养引发是一种具有成本效益和环境友好的生物强化方法。可以使用多种方法（例如锌肥、锌螯合化合物和锌纳米颗粒）用锌对种子进行营养处理。由于其众多优势和巨大的生物强化潜力，如今使用纳米颗粒进行营养引发越来越受欢迎。富含锌的种子也有助于植物在缺锌土壤中的表现。锌是一种必需的微量元素，可以调节植物细胞的生理、生化和分子过程，从而提高食用作物的发芽、生长、产量和生物利用度锌。此外，锌已成为治疗 COVID-19 症状的重要选择元素。富含锌的种子也有助于植物在缺锌土壤中的表现。锌是一种必需的微量元素，可以调节植物细胞的生理、生化和分子过程，从而提高食用作物的发芽、生长、产量和生物利用度锌。此外，锌已成为治疗 COVID-19 症状的重要选择元素。富含锌的种子也有助于植物在缺锌土壤中的表现。锌是一种必需的微量元素，可以调节植物细胞的生理、生化和分子过程，从而提高食用作物的发芽、生长、产量和生物利用度锌。此外，锌已成为治疗 COVID-19 症状的重要选择元素。
