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.
