biostudies-literatureUnknown15(3)Guzman-Baez GAThis study examined the effects of applying silver nanoparticles (AgNPs; 0, 5 and 10 mg L^-1) in a hydroponic system for seven days on growth parameters and on nutrient and phytohormone concentrations in two tomato cultivars, Vengador and Rio Grande. The results indicated that AgNPs at concentrations of 5 and 10 mg L^-1 did not change leaf number, stem length, or fresh/dry biomass weight. In leaves of Vengador, P and K concentrations decreased, while Mg and S increased in response to AgNPs. In stems and roots, both P and K decreased. Zn concentrations increased in leaves, Mn in stems and roots. In leaves of Rio Grande, K, Mg, S, Cu and Mn concentrations increased, while P decreased in AgNP-treated plants, as compared to the control. In stems, N, S and Mn concentrations Plants (Basel, Switzerland)405https://www.ebi.ac.uk/biostudies/studies/S-EPMC12899181biostudies-literatureInfluence of Silver Nanoparticles (AgNPs) on Vegetative Growth and Concentrations of Nutrients and Phytohormones in Tomato.PMC12899181Navarro-Lopez DEGuzman-Baez GAGomez-Merino FCTrejo-Tellez LIMejia-Mendez JLfalseInfluence of Silver Nanoparticles (AgNPs) on Vegetative Growth and Concentrations of Nutrients and Phytohormones in Tomato.This study examined the effects of applying silver nanoparticles (AgNPs; 0, 5 and 10 mg L^-1) in a hydroponic system for seven days on growth parameters and on nutrient and phytohormone concentrations in two tomato cultivars, Vengador and Rio Grande.
