The effects of elevated CO_2 (approximate doubling of atmospheric CO_2 concentration) on the rate of photosynthesis estimated from continuous monitoring of CO_2 exchange in whole plants were investigated in radish cv. Kosena accompanied with simultaneous analysis of growth for 6 days from 15 to 21 days after planting (DAP). The elevated CO_2 increased the dry weights of hydroponically grown radish plants by 59% at 21 DAP. The increase in dry weight was due to a combined effect of increased leaf area and increased photosynthetic rate per unit leaf area. Leaf area and the photosynthetic rate were increased by elevated CO_2 by 18-43% and 9-20%, respectively, during 15 to 21 DAP. Namely, an increase in the rate of photosynthesis is accompanied by an increase in leaf area, both having a significant effect on biomass production.
