Tomato is an important crop due to its nutritional contributions and organoleptic properties, which make it an appetizing vegetable around the world. In its sowing, the use of seed is the most accessible propagation mechanism for farmers. However, the induction to germination and emergence is often limited in the absence of stimulants that promote the development and growth of the seedling, added to the interference of infectious agents that notoriously reduce the vitality and viability of the seed. Given this, it was proposed as a research objective to determine the effect of zinc oxide nanoparticles (ZnO NPs) mediated by a green route on the germinative characteristics of Mill. 1768 "tomato". The experimental phase consisted of the synthesis of ZnO NPs and its subsequent characterization. After its synthesis, its inoculation was conducted during the germination of seeds of , considering six sample groups for the treatment with zinc nanoparticles (T1: Control; T2: 21.31 ppm; T3: 33.58 ppm; T4: 49.15 ppm; T5: 63.59 and T6: 99.076 ppm). The results indicate that concentrations close to 100 ppm of ZnO NPs are ideal in the treatment of seeds, due to the promotion of enzymatic and metabolic activity to achieve cell elongation; likewise, the biosynthesized nanoparticles showed no phytotoxicity, due to the fact that, in all the treatments, there were processes of germination and emergence. This was linked to the generation of a Zn-phenolate complex through a chelating effect, which generates compatibility with the seed and, compared to classic inorganic synthesis, usually shows phytotoxicity. In this sense, green synthesis is presented as a great alternative in this type of application.
番茄因其营养价值和感官特性而成为一种重要的作物，使其成为全球开胃的蔬菜。在播种时，种子的使用是农民最容易获得的繁殖机制。然而，在没有促进种子幼苗发育和生长的刺激物的情况下，发芽和出苗往往受到限制，加上传染性病原体的干扰，这些病原体明显降低了种子的活力和生存能力。考虑到这一点，我们提出了一个研究目标，即确定通过绿色途径介导的氧化锌纳米粒子（ZnO NPs）对 1768 年“番茄”品种的发芽特性的影响。实验阶段包括 ZnO NPs 的合成及其随后的表征。合成后，在种子发芽期间进行了其接种，考虑了用锌纳米粒子处理的六个样品组（T1：对照；T2：21.31 ppm；T3：33.58 ppm；T4：49.15 ppm；T5：63.59 和 T6：99.076 ppm）。结果表明，接近 100 ppm 的 ZnO NPs 浓度是处理种子的理想浓度，因为它促进了酶和代谢活性，以实现细胞伸长；同样，生物合成的纳米粒子没有显示出植物毒性，因为在所有处理中，都有发芽和出苗的过程。这与通过螯合作用生成 Zn-邻苯二酚配合物有关，该配合物与种子具有兼容性，并且与经典的无机合成相比，通常显示出植物毒性。从这个意义上说，绿色合成在这种类型的应用中是一种很好的替代方法。
