Abstract

Carbon isotope discrimination (∆) was measured for leaves of Atriplex confertifolia along a salinity gradient in northern Utah. Over this gradient, the variation of ∆ values was high for a C₄ species, and the ∆ values were positively correlated with salinity in both years of study. Of the possible explanations for this pattern, the ∆ results are consistent with the notion that salinity induces an increase in the bundle sheath leakiness of these C₄ plants.
