Abstract

Hydrogen and carbon isotope ratios of saponifiable lipids and cellulose nitrate from CAM, C₃, and C₄ plants that grew near one another were determined. The deuterium/protium (D/H) ratios of cellulose nitrate from CAM plants were much higher than those of cellulose nitrate from C₃ and C₄ plants, as has been observed previously. In contrast, the D/H ratios of saponifiable lipids from CAM plants did not differ from those of the same fraction from C₃ and C₄ plants. These observations indicate that deuterium enrichment in cellulose of CAM plants is not caused by any metabolic or physiological process which would lead to deuterium enrichment in all biochemical fractions.
