Other claims from this paper (11)
- Observation Fluoride taken up by tea plants was readily transported, especially to leaves.
- Association Leaf fluoride increased linearly with uptake-solution fluoride concentration.
- Association Leaf fluoride increased linearly with soil fluoride concentration.
- Association Root and stem fluoride was only marginally influenced by fluoride availability.
- Intervention effect Al in solution increased fluoride uptake and movement to leaves.
- Intervention effect Al addition to soil increased fluoride uptake and movement to leaves.
- Intervention effect 74.1 µmol l −1 Al increased leaf fluoride by 37.7% versus no Al over 22 h.
- Intervention effect Soil Al application increased fluoride in mature leaves.
- Intervention effect Soil Al application increased fluoride in new shoots.
- Intervention effect Leaf Al concentration was unaffected by fluoride and Al treatments.
- Intervention effect New shoots had higher Al concentrations following soil Al and fluoride additions.
