Abstract Carbon isotope discrimination (Delta) was measured for leaves of Atriplex confertifolia along a salinity gradient in northern Utah. Over this gradient, the variation of Delta values was high for a C-4 species, and the Delta values were positively correlated with salinity in both years of the study Of the possible explanations for this pattern, the Delta results are consistent with the notion that salinity induces an increase in the bundle sheath leakiness of these C-4 plants.
