Key Laboratory of Forest Tree Genetic Improvement and Biotechnology of Ministry of Education, Northeast Foresty University, Harbin 150040, China 3. Institute of Microbiology, Heilongjiang Academy of Sciences, Harbin 150010, China)  
To study physiological response of Populus simonii×P.nigra to salt stress, SOD activity, POD activity, MDA content and relative content of chlorophyll were measured at 6 h, 1 d, 2 d, 4 d, 6 d, 8 d under 0, 75, 150, 250 mmol/L NaCl stress. As the salt concentration increased and the stress time continued, POD and SOD activity increased gradually and then decreased. MDA content was increased and chlorophyll content was decreased gradually.
