Benefits of nanotechnology in agriculture include reduced fertilizer loss, improved seed germination rate and increased crops quality and yield. The objective of this research was to evaluate the effects of zinc oxide nanoparticles (ZnO-NPs), at 1500 ppm, on tomato ( L.) growth. ZnO-NPs were synthetized to produce either spherical or hexagonal morphologies. In this research, we also studied two application methods (foliar and drench) and nanoparticles' (NPs) surface modification with maltodextrin. The results obtained indicate that ZnO-NP-treated tomato plants significantly increased plant height, stem diameter and plant organs (leaves, stem and root) dry weight compared to plants without NP treatment.
纳米技术在农业中的益处包括减少肥料损失、提高种子发芽率以及增加作物的质量和产量。本研究的目的是评估氧化锌纳米粒子（ZnO-NPs）在 1500ppm 浓度下对番茄（L.）生长的影响。ZnO-NPs 被合成以产生球形或六方形态。在这项研究中，我们还研究了两种应用方法（叶面喷施和浸种）和用麦芽糊精对纳米粒子（NPs）进行表面修饰。结果表明，与未经 NP 处理的植物相比，用 ZnO-NP 处理的番茄植物的株高、茎直径和植物器官（叶片、茎和根）干重显著增加。
