The research of simultaneous measurements of CO2 exchange and growth have been continued to evaluate the impact of photosynthesis on biomass. Plants of radish, cv White Cherrish with big storage root were grown for 6 days under 4 different conditions (1: ambient CO2 of ca. 380 ppm and 23 molE/m2+/day, 2: elevated CO2 of ca. 750 ppm and 23 molE/m2+/day, 3: ambient CO2 of ca. 380 ppm and 15 molE/m2+/day, 4:elevated CO2 of ca. 750 ppm and 15 molE/m2+/day) and the rates of CO2 exchange were monitored continuously during whole periods of growth analysis. The results of growth analysis of RGR, NAR, LAR, LWR, SLA, leaf area, rates of photosynthesis and respiration, and water use efficiencies under 4 different conditions will be discussed comparing the results with radish cv. Kosena with small storage root which was presented last year.
