Abstract

Respiratory measurements of apical root parts of several C4 plant species (Echinochloa crus-galli var. crus-galli, Setaria pumila and Zea mays DK 312 (Dekalb, USA) subjected to an elevated CO₂ regime during growth in climatic chambers or at natural CO₂ springs were performed. Biomass production, root respiratory potential and root respiration of Echinochloa was not significantly changed by high atmospheric CO₂ treatment in the climatic chambers, compared to ambient CO₂ treatment. Root respiratory potential of C4 weeds (Echinochloa crus-galli and Setaria pumila) growing in natural CO₂ spring area was not significantly affected by extremely
high CO₂ in the rhizosphere. Yet, respiratory potential of one and a half month old sown maize seedlings was significantly lower in the roots exposed to naturally elevated CO₂ concentrations.
