Summary

Sulfur concentrations of western wheatgrass tillers and individual leaves were measured from plants exposed to four SO2 concentrations (9, 52, 105 and 183 μg·m−3). Sulfur concentration of plants was a linear function of either time of exposure or concentration.

Young leaves and the youngest portion of leaves contained less sulfur than their older counterparts irregardless of whether they had or had not been exposed to SO2.

Current hypotheses which relate plant sensitivity to amount of sulfur taken up do not apply for western wheatgrass.
