Variation in the carbon isotope composition of a plant with crassulacean acid metabolism

Variation in the carbon isotope composition of a plant with crassulacean acid metabolism

The content of 13C varies in plants with Crassulacean acid metabolism. Differences up to 3.5‰ in the 13C/12C ratios were observed between leaves of different age in the same plant of Bryophyllum daigremontianum. Soluble and insoluble carbon in the same leaf differed up to 8‰, the largest difference...

Zusammenfassung:The content of 13C varies in plants with Crassulacean acid metabolism. Differences up to 3.5‰ in the 13C/12C ratios were observed between leaves of different age in the same plant of Bryophyllum daigremontianum. Soluble and insoluble carbon in the same leaf differed up to 8‰, the largest difference occurring in the leaves with the highest Crassulacean acid metabolism activity. Models to account for the isotope discrimination by C3, C4, and Crassulacean acid metabolism plants are proposed.
