Fig. 6. Mean yield and harvest index (HI) of USU-Apogee and Super Dwarf wheat with and without 50 nmol mol^-1 C₂H₄ at three levels of CO₂. Yields are normalized to percent of the control at 1200 µmol mol^-1 CO₂ for ease of comparison. HI was calculated assuming the root mass to be 10% of the total above ground biomass.
