Abstract
This research studied the effect of titanium dioxide nanoparticles (TiO2NPs) on faba beans plant grown under salinity stress. Plants exposed to two different salinity levels (40 and 80 mM NaCl) were treated with two different concentrations of TiO2NPs (5, 10 ppm) during the growth period. Data showed that the high salinity levels decreased the plant height, fresh and dry weights of the shoots by (12.4 %, 37.2 %, and 34.8 %) respec-tively, as well as decreased (Chl a, Chl b, Total Chl and carotenoids content) by (43.7 %, 45.7 %, 44.2 %, and 12.1 %) respectively compared with the control. The application of TiO2 NPs at (10 ppm) improved significantly faba plant height, fresh and dry weights of the shoots by (10.9 %, 67.3 %, and 33.4 %) respectively, as well as improved significantly (Chl a, Chl b, Total Chl and Carotenoids) by (58.8 %, 19.7 %, 47.6 %, and 37.7 %) re-spectively compared with the untreated plants. It could be concluded that spraying with TiO2NPs at the two used concentrations mitigated the harmful effects of salinity on faba bean plants.
