Abstract:

Abstract: The study was conducterd with four halophytes with different salt-sistance under NaCl conditions. 6 physiological salt resistance characteristics were measured,such as chlorophyll content, MDA content, proline content, SOD activity, CAT activity and POD activity. And a comprehensive evalution on salt resistance of four plants was given based on subordinate function values analysis. The degree of salt tolerance as follows: Tamarix chinensis>Nitraria schoberi >Limonium aureum>Achnatherum splendens.
