Title: Synthesized tio2 nanoparticles mitigating salinity stress in okra plants via foliar application

Abstract

Titanium dioxide nanoparticles (TiO2 NPs) are increasingly recognized for their potential to enhance plant growth. In this study, we report the synthesis of titanium dioxide nanoparticles (TiO2 NPs) by modified sol-gel method. A number of characterization techniques including X-ray Diffraction, and Field Emission Scanning Electron Microscopy, Energy Dispersive X-ray and Raman spectroscopy confirm the synthesis of anatase TiO2 NPs with uniformly quasi-spherical morphology. Furthermore, we investigated the effects of foliar application of prepared TiO2 NPs at 100 and 150 ppm on okra (Abelmoschus esculentus) grown under salt stress (100 ppm NaCl). Salinity negatively affected all measured agronomic traits; however, treatment with TiO2 NPs mitigated these adverse effects. Treated plants exhibited improved growth and yield-related characteristics, alongside higher concentrations of chlorophyll a, chlorophyll b, total chlorophyll, and carotenoids. These findings indicate that foliar application of TiO2 NPs at 100 and 150 ppm may play an important role in alleviating the detrimental effects of salinity stress on okra.
