Effects of EDTA on Seedlings Growth of Raphanus L.under Lead Treatment

WU Shun,LUO Guang-yu,PENG Li-xia(School of Life Science and Technology,Central South University of Forestry and Technology,Changsha,Hunan 410004,China)  
Effect of EDTA on Raphanus L.seedlings under lead stress was studied by straying different concentration EDTA in course of their growth.The results showed that memberane permeability increased,POD and SOD activity and soluble protein content decreased in the Raphanus L.seedlings under 300 mg/L lead stress.Memberane permeability firstly decreased and then increased,POD and SOD activity and soluble protein content firstly increased and then decreased after Raphanus L.seedlings were strayed by different concentration EDTA.this showed that EDTA can alleviation the poison effect of lead on Raphanus L.seedlings in certain concentration scop,and 0.75 μmol/L EDTA had the best effect.
