| Abstract: |
| Under hydroponics,the relations of copper (Cu) accumulation, growth characters and proteins expression were investigated in roots, stems and leaves of Elsholtzia haichowensis after the different concentration of CuSO4 treatment 7 days. The results showed that Cu treatment significantly increased Cu accumulation in E. haichowensis, 10 μmol/L Cu treatment significantly accelerated the growth of E. haichowensis, but the more concentration Cu treatment decreased the growth of E. haichowensis. The total biomass arrived at the most under 100 μmol/L Cu treatment, at the same time, this treatment inhibited root elongations and decreased chlorophyll contents in E.haichowensis, therefore, some low molecular mass proteins in roots and leaves of E. haichowensis was induced under Cu treatment, which may be related with the copper tolerance of E. haichowensis. |
