摘要：

The influence of titanium dioxide nanoparticles (TiO(2)NPs) biofabricated with leaf extract of Terminalia catappa for modulating Abelmoschus esculentus characteristics was investigated. The TiO(2)NPs were characterized to be monoclinic-shaped-crystalline-clustered particles with a characteristic peak at 366 nm and particle size of 75.24 +/- 1.12 nm. A. esculentus seeds were grown on soil amended with different concentrations of TiO(2)NPs and water for 28 days. The TiO(2)NPs-grown A. esculentus had enhanced germination percentage from 40 to 60%; root length from 15.75 to 23.96 cm; shoot length from 19.40 to 32.20 cm and reduced its perishability by 82.35%. The antioxidant activity and photosynthetic parameters were improved with reduction in malondialdehyde contents by 46.84% in TiO(2)NPs-grown A. esculentus. The potassium (K) contents were significantly stimulated in the tissues of TiO(2)NPs-grown A. esculentus. This study has shown that TiO(2)NPs elicited positive responses in A. esculentus for better performance.
