This paper discusses the potential ways in which C3 plant performance may benefit from a future high-CO2 environment. These include increases in the efficiencies for light, nitrogen and water utilisation, particularly at elevated temperatures, resulting from the improvement which will occur in the performance of the primary carboxylating enzyme, Rubisco. However, while growth experiments at elevated CO2 indicate that C3 plants show stimulation of dry matter accumulation, the potential gains are greatly ameliorated by a redistribution of plant resources. This primarily occurs via a reduction in the leaf area ratio which offsets increases in the net assimilation rate. In addition, there may be an overcommitment of nitrogen in key photosynthetic components such as Rubisco and the thylakoid electron transport system. It is concluded that plants may not be genetically adapted to optimise their growth and performance at elevated CO2 and that consideration should be given to exploring avenues for manipulating plants for more optimal responses. Targets for improvement of growth at elevated CO2 include (1) altering source-sink relations; (2) improving the redistribution of nitrogen between the photosynthetic machinery and the rest of the plant; and (3) changing the response of stomata to CO2 and humidity to increase water-use efficiency even further than is currently predicted.

Pot experiment was conducted using eggplants (Solanum melongena L.) grown in a controlled growth chamber environment. Ambient (370 ppm) and elevated (700 ppm) CO2 concentrations, were used. Hydraulic conductance in stressed eggplants was lower than that of control eggplants and this phenomenon was enhanced under elevated CO2 environment and also due to plant age. Hydraulic conductance through the root system in free water was comparatively higher than that of soil medium. As in the pressure plate apparatus technique with moist soil, the eggplants that experienced repetitively shorter stress showed the lowest conductance (6.38 × 10-5 kg/m2/s/MPa) under the interactive effects of high CO2 and water stress while control and longer stressed plants had 9.11 × 10-5 and 7.19 × 10-5 kg/m2/s/MPa, respectively. It appeared that eggplants grown in a high CO2 environment might be efficient in water use under soil water shortage conditions.
