Leaf, stem, and root stable carbon isotope ratios and gas exchange data for 452 plants

This dataset contains a compilation of stable carbon isotope ratios in leaves, stems, and roots for tree saplings and associated gas exchange data. It was used in a book chapter to test whether the relationship between carbon isotope discrimination and the ratio of intercellular to ambient carbon dioxide concentrations differs between leaves and woody tissues. The book chapter is entitled 'Carbon isotope effects in relation to CO2 assimilation by tree canopies' authored by Lucas A. Cernusak and Nerea Ubierna. It is part of the book entitled 'Stable Isotopes in Tree Rings' edited by Rolf T. Siegwolf, J. Renee Brooks, John Roden, and Matthias Saurer. The publisher of the book is Springer International Publishing, with publication in April 2022.
