A review on Fluorides Uptake Characters of Tea Plant (Camellia sinensis L.)

다국어 초록 (Multilingual Abstract)

Tea plants accumulate large amounts of fluoride while the mechanism of F uptake by tea plants is still unclear. The objectives of this study are, therefore, to summarize recent researches about F uptake characters of tea plants especially pH, Al, Ca, anion channel blockers and metabolism inhibitors influences. Al facilitating F uptake by tea plants might have occurred mainly in the processes of uptake and been less likely during the translocation from roots to shoots. And it was convinced that the concentration of F in tealeaves reached maximum, when soil pH came to 5.5. Meanwhile Ca was important for the stabilization of plant cell walls and membranes. Reasonably, the reduced F uptake by tea plants was possibly related to a decreased passage of F as the properties of the cell wall or membrane permeability were altered considerably by Ca addition. Also the uptake of F by roots of accumulator tea plants was likely an active process and energy dependent and probably through a kind of anion transport system.
