PLoS ONE 15(12):Įditor: Amitava Mukherjee, VIT University, INDIA The positive effect of the Ag-TiO 2 NPs treatment could be associated to the generation of reactive oxygen species, antimicrobial activity, increased biochemical attributes, enzymatic activity or improvements in water absorption.Ĭitation: Gordillo-Delgado F, Zuluaga-Acosta J, Restrepo-Guerrero G (2020) Effect of the suspension of Ag-incorporated TiO 2 nanoparticles (Ag-TiO 2 NPs) on certain growth, physiology and phytotoxicity parameters in spinach seedlings. The inoculation with NPs of 8.3 nm size and lowest concentration was related to the highest average ROE value, 24.6 ± 0.2%, while the control group was 20.2 ± 0.2%. The statistical trend indicated that the application of the Ag-TiO 2 NPs suspension of lowest concentration and smallest particle size could be a promoting agent of the growth and development of these plants. The analysis of variance showed that the dependent variable (plant growth) could be affected by the evaluated factors (concentration and size) with significant differences. Samples of TiO 2 powder with particle size between 9 and 43 nm were used to quantify the germination rate, which served to determine a narrower size range between 7 and 26 nm in the experiments with Ag-TiO 2 NPs the presence of Ag in TiO 2 powder samples was confirmed by energy-dispersive X-ray spectroscopy. The photosynthetic activity of the spinach plants was estimated through the quantification of the Ratio of Oxygen Evolution (ROE) by the photoacoustic technique. ![]() These NPs were obtained by means of the sol-gel method and heat treatment the resulting powder material was characterized using X-ray diffraction and scanning electron microscopy and the influence of these NPs on plants was measured by estimating the germination rate, monitoring morphological parameters and evaluating phytotoxicity. ![]() This is an important crop for human consumption with high nutritional value due to their low calorie and fat content, providing various vitamins and minerals, especially iron. In this work, the effect of the inoculation of silver-incorporated titanium dioxide nanoparticles (Ag-TiO 2 NPs) in spinach seeds was evaluated on certain growth, physiology and phytotoxicity parameters of the plants. ![]()
