The authors found five sodium (Na + ) and chloride (Cl ‐ .) hyperaccumulating halophytes in the Temperate Desert of Xinjiang, China and studied two of them ( Suaeda salsa (L.) Pall. and Kalidium folium (Pall.) Moq.). K. folium and S. salsa had a NaCl content of 32.1% and 29.8%, respectively, on a dry weight basis. X‐ray microanalysis of the Na+ in the vacuole, apoplasts and cytoplasm of the two plants indicated a ratio of 7.3:5.6:1.0 in K. folium and 7.3:6.6:1.0 in S. salsa. These data show that K. folium and S. salsa both have a high Na + and Cl ‐ accumulating capacity, which is related to high activity of tonoplast H + ‐ATPase and H + ‐PPase. (Managing editor: Ping HE)
