Physiological and agronomical traits effects of titanium dioxide nanoparticles in seedlings of Solanum lycopersicum L.

ABSTRACT:

Background

Titanium dioxide nanoparticles (TiO₂ NPs) have been reported to have contrasting effects on plant physiology, while their effects on sugar, protein, and amino acid metabolism are poorly understood. In this work, we evaluated the effects of TiO₂ NPs on physiological and agronomical traits of tomato (Solanum lycopersicum L.) seedlings. Tomato seeds were treated with TiO₂ NPs (1000 and 2000 mg L^- 1), TiO₂ microparticles (µPs, 2000 mg L^- 1) as the size control, and ultrapure water as negative control.

Results

The dry matter of stems (DMs), leaves (DMl) and total dry matter (DMt) decreased as particle concentration increased. This trend was also observed in the maximum quantum yield of light-adapted phot
