Interaction Between Arsenic and Phosphorus,Potassium,Calcium and Other Nutrient Elements in Pteris vittata L.

Arsenic pollution has poisoning effect on plant,animal and human being.The interaction between arsenic and phosphorus、potassium,calcium and other elements was studied.The results showed that:in Pteris vittata L.,phosphate concentration increased with the increasing of arsenic concentration of culture medium;there was no antagonism relationship between them,but there was significant positive correlation between the phosphate concentration of potassium concentralion in leaf epidermal cells;besides the phosphate accumulation was limited by the level of phosphate and calcium.The magnesium concentration of root decreased with the increaseing of phosphate concentration,but it had no infulence on the magnesium concentration of petiole and leaves.
