Abstract：The corn seedlings in hydroponic culture are treated with the lead acetate solutions of various concentrations, the content of Pb2+ in the roots, stems and leafs of the corns at 10th day, 20th day and 30th day is measured.The analyzing conclusions are that the contents of Pb2+ in the corns display a sequence of root＞leaf＞stem, the contains of chlorophyll in corns fall off, the raising of Pb2+ in solutions, the membrane penetrability of the corns increased along a sequence of root＞leaf＞stem，and the harmful rate of Pb2+ display a sequence of root＞leaf＞stem in corns.The data of the study gives some references for the further researches of the crops, relating the endurance and the distributing of corns with Pb2+.
