title: [The corn seedlings are affected by the heavy metal Pb2+].
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+.
