A crucial stage of plant development is seed germination, and new techniques employ nanomaterials to raise plant seed germination indices. The purpose of this study was to evaluate how lab-prepared zinc oxide nanoparticles affected the vigor and germination of chili seeds. Zinc oxide nanoparticle dispersion was soaked into chili seeds at five different concentrations (10 ppm, 20 ppm, 30 ppm, 40 ppm, and 50 ppm). The treated seeds were then kept for one to two weeks at room temperature before being checked for germination in petri dishes. Every day, germination was monitored, and the length of the seedlings was recorded. The findings demonstrated that ZnO nanoparticles had a substantial impact on root length, shoot length, seedling length, and germination percentage. The highest percentage of seeds that germinated were treated with 10 ppm ZnO NP. It has been discovered that higher ZnO nanoparticle concentrations are associated with improved seed germination; however, increasing the concentration above 40 ppm has a negative impact on the seed. It was discovered that the length of the roots, shoots, and seedlings was maximal in lower concentrations and decreased in increasing concentrations. In comparison to the control seeds, chili seeds primed with ZnO nanoparticles were found to retain seed viability and even show a discernible degree of germination increase. In general, the enhanced reaction of chili seeds in the initial phases of their growth is positive for the use of ZnO NPs for seed priming in order to improve germination indices. © 2025 Author(s).
