| Summary: | The effects of elevated CO2 (approximate doubling of atmospheric CO2 concentration) on the rate of photosynthesis estimated from continuous monitoring of CO2 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 CO2 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 CO2 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. |
