The influence of carbon dioxide on growth and protein
synthesis of etiolated Avena coleoptiles was investigated.
Evidence is presented that 0.03% carbon dioxide stimulated both
these processes; and that carbon dioxide stimulated growth depends
on carbon dioxide stimulated protein synthesis, In addition the
evidence indicates that carbon dioxide stimulated growth is mediated
by metabolism, and that carbon dioxide stimulates growth through a
dark fixation process. Growth studies also demonstrated that
IAA and carbon dioxide stimulated growth in a synergistic
manner
