| Abstract: | The effects of Cu2+ stress on maize seedlings by using scanning electron microscope, X-ray energy spectrum and Fourier transform infrared attenuated total reflection(FITIR-ATR) spectrometry were investigated, and antioxidative enzymes activities such as SOD, CAT, POD, APX were measured. Results showed that, with the increasing of Cu2+ concentration, the content of chlorophyll decreased, and antioxidative enzyme activities increased at first and then decreased at higher concentration stress. High concentration Cu2+ treatment twisted the cells' shape and increased copper content on leaf surface, and absorption of other nutrients were also affected The result of FTIR-ATR analysis showed that the organic content of leaf were changed by Cu2+ stress. |
| Keywords: | copper stress maize X-ray energy spectrum FTIR-ATR antioxidative enzymes |
