Industrial fluoride pollution of Jerbi grape leaves and the distribution of F,Ca, Mg, and P in them

Year: 2006

Type: article

Abstract: Fluoride damaged leaves of the Jerbi grape vine tree (Vitis vinifera L) growing in the vicinity of a phosphate fertilizer manufacturing plant near Sfax, Tunisia, were used to study the distribution of the chemical elements F, Ca, Mg, and P in the leaves and stalks. Photosynthesis and the chlorophyll content of healthy leaf parts were also investigated to determine tolerance mechanisms of this species to fluoride. The subdivision of the necrotic zone into concentric necrotic halos evidently reflects a series of plant reactions to preserve a large portion of the leaf assimilatory surface. Photosynthesis still occurred with 30 to 40% necrosis of the leaves. Preferential accumulation of F was found in the leaf margins along with a parallel accumulation of Ca. Necrosis becomes evident when a fall in Ca occurs with an excess of F. After this happens, the plant tends to maintain high Mg and P concentrations in its healthy leaf parts. At 60% leaf necrosis, F seems to be effective in reducing photosynthesis and chlorophyll content.
