The agriculture sector faces numerous problems. One of the beforementioned problems relates to the proper crop plants’ fertilization. The conventional bulk fertilizers are becoming less effective and have a negative impact on the environment. Nanomaterials such as zinc oxide nanoparticles (ZnO NPs) are widely used in various sectors such as medicine or electronics. Several studies indicate that nano-ZnO may likewise be considered as a potential nanofertilizer. In present research, an attempt was made to study the influence of two different sized ZnO NPs (<50 nm and <100 nm) on the seed germination of chosen tomato (Solanum lycopersicum) cultivars. The seeds of three cherry tomato cultivars were placed on a Petri dish with the NPs suspensions (0, 50, 150, and 250 mg/L) in order to examine the influence on germination parameters at a certain size of NPs and at a chosen concentration. In addition, within this study, we verified that the implicated conditions have the exact impact on all three cultivars. The obtained results indicate that all the factors affect the seed sprouting, however, this process mainly depends on the type of tomato cultivar and the size of the used nanoparticles. The parameter of the germination percentage (GP) was the only of the assumed factors that did not influence it significantly. Nevertheless, the values of other examined parameters such as the MGT, GRI, CVG, or VI depend strongly on all assumed features including the type of chosen cultivar. The obtained results vary significantly between all cultivars which indicates that the plants from the same family may require different conditions for optimal growth. In this research the <50 nm ZnO nanoparticles had more beneficial influence on sprouting parameters then parallelly used <100 nm ZnO nanoparticles.
农业部门面临着许多问题。前文提到的问题之一与作物的适当施肥有关。传统的大量肥料的效果越来越差，对环境也有负面影响。氧化锌纳米粒子（ZnO NPs）等纳米材料广泛应用于医学或电子等各个领域。有几项研究表明，纳米 ZnO 也可以被视为一种潜在的纳米肥料。在目前的研究中，尝试研究了两种不同尺寸的 ZnO NPs（<50nm 和 <100nm）对所选番茄（Solanum lycopersicum）品种种子萌发的影响。将三种樱桃番茄品种的种子放在含有 NPs 悬浮液（0、50、150 和 250mg/L）的培养皿上，以研究在一定尺寸的 NPs 和选定浓度下对萌发参数的影响。此外，在这项研究中，我们验证了所涉及的条件对所有三个品种都有确切的影响。研究结果表明，所有因素都影响种子发芽，但这一过程主要取决于番茄品种的类型和使用的纳米粒子的尺寸。发芽百分比（GP）参数是唯一未显著影响的假定因素。然而，其他检查参数的值，如 MGT、GRI、CVG 或 VI，强烈依赖于所有假定的特征，包括所选品种的类型。所有品种的研究结果差异显著，这表明来自同一科的植物可能需要不同的条件才能最佳生长。在这项研究中，<50nm ZnO 纳米粒子对发芽参数的影响比同时使用的<100nm ZnO 纳米粒子更有益。
