Abstract: Effect of different pretreatment on cold resistance of Euonymus fortunei‘Hong Mai’was investigated.Lipid peroxidation,protective enzyme activity and osmotic adjustment were analysed.The result showed that the young plants by cold stress after pretreatment with 0.1 and 0.3 mol/L NaCl put up lower lipid peroxidation,higher defense enzymes activities and more osmotic adjustment.Compared with different PEG concentration,salt concentraton could more effectively advance the cold resistance of Euonymus fortunei.The results proved different stress pretreatments could improve the resistance of the Euonymus fortunei young plants.The cross adaption of plants to different environmental stresses involved certain common molecular mechanism.

Key words: Euonyumus fortunei, pretreatment, cross adaption, cold resistance
