Abstract
Abstract Several elevated concentrations of CO 2 were injected into the root atmosphere to determine the influence of CO 2 concentration in the soil on the growth of eggplant ( Solanum melongena L.). Elevated CO 2 levels in the root atmosphere consistently increased stem diameter while a significant increase in plant total dry weight and leaf area only occurred during long day/warm temperature conditions. Under periods of short days and low light levels, 15% CO 2 reduced total dry weight and leaf area. Applications of 14 CO 2 to the root zone demonstrated that 14 C eggplant roots absorb CO 2 from the soil environment and translocate labeled compounds into the shoot.
