Foliar applications of plant-based titanium dioxide nanoparticles to improve agronomic and physiological attributes of wheat (<i>Triticum aestivum</i> L.) plants under salinity stress

Abstract The present study was carried out to investigate the beneficial and toxicological effect of plant-based titanium dioxide nanoparticles (TiO 2 NPs) on morphophysiological attributes wheat plants under salinity stress. biogenesis accomplished by using extract Buddleja asiatica L. leaves followed characterization through UV visible spectroscopy, SEM, FTIR, EDX. NaCl salt applied in two different concentrations after 21 days germination foliar applications various TiO NPs (20, 40, 60, 80 mg/L) salinity-tolerant (Faisalabad-08) salinity-susceptible (NARC-11) varieties 10–15 application Salinity stress showed remarkable decrease selected varieties. Magnificent improvement plant height, dry fresh weight plants, shoot root length, weight, number per plant, RWC, MSI, chlorophyll a b, total contents has been observed when 40 mg/L used. However, parameters decreased gradually at higher (60 both Therefore, concentration found most preferable increase growth agronomic physiological salinity.
