Resumo

Nanopriming is a simple and cost-effective method for seed germination and consists in using nanoparticles (NPs) in a solution for a determined period. In this paper, sunflower seeds were primed with water and silver NPs produced with aminolevulinic acid (ALA) and Mimusops Coriacea leaves extract, both synthesized by the photoreduction method. The fluorescence spectra and decay time of the chlorophyll extract of seedlings ten days after nanopriming were measured. The results indicated that silver NPs increased seed germination, seedling growth, and chlorophyll production compared to water-primed seeds. No toxicity was observed with the presence of silver NPs (AU)
