SUMMARY The internal atmosphere of gibbous as well as flat modifications of Lemna gibba G3 v , as determined by gas chromatography after cultivation in vitro under conditions of continuous light. A similar analysis was done on a gibbous strain of L. gibba collected in the field. The gaseous constituents of the air chambers were found to be N 2 , O 2 and CO 2 . The CO 2 concentration was approx. 1% in gibbous forms of strain G3 as well as the field strain and approx. 3% in flat forms of strain G3. The O 2 concentrations tended to be slightly higher in the gibbous forms than in the flat. The CO 2 to O 2 ratio of the flat modification was much higher than in the gibbous forms. The remaining part of the internal atmosphere consisted of nitrogen. Methane and ethylene could not be detected.
