Abstract: Changes of activated oxygen O2·, activity of enzymes involving cell defense in leaves of maize seedling after effects of low temperature and light were studied.The results showed that the generation rate of activated oxygen O2· increased;the activities of SOD and CAT decreased and POD increased under different low temperature stress;many notable distinguishes in facts such as generation of activated oxygen O2· and changes of the activities of SOD, CAT, POD had been found between light and dark after the same low temperature stress.

Key words: maize seedling, low temperature stress, light, activated oxygen, cell defense enzyme
