Acclimation of Respiratory O 2 Uptake in Green Tissues of Field - Grown Native Species after Long - Term Exposure to Elevated Atmospheric C 02 ' Joaquim


C3 and C, plants were grown in open-top chambers in the field at two CO, concentrations, normal ambient (ambient) and normal ambient + 340 fiL 1-' (elevated). Dark oxygen uptake was measured in leaves and stems using a liquid-phase Clark-type oxygen electrode. High CO, treatment decreased dark oxygen uptake in stems of Scirpus olneyi (C,) and leaves of… (More)
