Photosynthesis by carrot tissue cultures

摘要

14CO2-fixation rates in green carrot callus cultres (about 35 μg chlorophyll/g fresh wt) were determined in gaseous and liquid media using a range of light intensities and CO2concentrations. Main products of light-dependent CO2-fixation were sucrose, alanine, glutamine, serine/glycine and malic acid. In darkness, glutamine and malic acid were formed
