Abstract
⺠TiO2-NP diameter, but not crystallinity, influences their transfer in plant tissues. ⺠Wheat roots accumulate TiO2-NPs with diameter up to 36 nm but not 140 nm TiO2-NPs. ⺠TiO2-NPs with diameter lower than 36 nm are translocated from wheat root to shoot. ⺠A 100 mg/L TiO2-NP wheat root exposure leads to Ti root content up to 110 μg/g d.wt. ⺠Exposure of wheat to the smallest TiO2-NP induces increased root elongation.
