Abstract: | Abstract The mineral ion contents of seven halophytic species in the family Chenopodiaceae, and associated soils were examined. Each species was found growing in soils with wide ranges of salinity, sodicity and salt ion composition. Absolute concentrations of Na, Ca, Mg, K, Cl and SO4 in shoot tissue differed significantly among species. Species were classified into two groups: (1) chloride halophytes, with ion composition dominated by Na and Cl (Atriplex patula, Chenopodium rubrum, Salicornia rubra and Suaeda depressa), and (2) alkali halophytes, with relatively high K, Mg, Ca and low Cl contents (Chenopodium salinum, Kochia scoparia and Salsola pestifer). All species accumulated ? and excluded SO4, relative to concentrations of these ions in soil. Salsola pestifer was unique in strongly excluding Na. |
