Background and aims Arsenate (AsV) and chromate (CrVI) inhibit each other’s uptake and translocation in As-hyperaccumulator Pteris vittata. In the present study, we extended the research to As-sensitive plant Pteris ensiformis to better understand the mechanism of their interactions. Methods Plants were exposed to 0, 0.75 or 7.5 mg L−1 AsV and 0, 0.52, or 5.2 mg L−1 CrVI for 7 d in hydroponics....
We investigated the effects of arsenate (AsV) and fluoride (F) on each other’s uptake in an As-sensitive plant Pteris ensiformis. Plants were exposed to 1) 0.1 × Hoagland solution control, 2) 3.75 mg L−1 As and 1.9, 3.8, or 7.6 mg L−1 F, or 3) 1 mg L−1 F and 3.75 mg L−1 or 7.5 mg L−1 As for 7 d in hydroponics. P. ensiformis accumulated 14.7–32.6 mg kg−1 As at 3.75 mg L−1 AsV, and 99–145 mg kg−1 F...
