We mainly studied different alkali-salt and salt concentration on the physiological activity of Tripolium vulgare in this experimet and analyzed different changes on SOD、POD、proline and soluble protein of Tripolium vulgare in different salt and salt concentrations,at last,explained its adaptation to different salt.Results show that with the extension of salt-stress,SOD activity first decreases then increases,but POD is increased.with the change of time and concentration,Soluble protein first increases and t...
