Abstract: With different concentration of polyethylene glycol(PEG) the treatment of osmotic stress rhizosphere of sweet potato has been made. The test showed that plasmolemma permeability enhanced;malondialdehyde，total amino acid and free proline content increased;catalase activity increased and peroxidase a
