Effect of Low Concentrations of Carbon Dioxide on Photosynthesis Rates of Two Races of Oxyria

Alpine plants of Oxyria digyna have higher apparent photosynthesis rates at various carbon dioxide concentrations than arctic, sea-level plants of the same species. The ability to utilize carbon dioxide effectively at low concentrations may be involved in the survival of plants at high elevations.
