As a general rule, no isotopic fractionation occurs during water uptake and water transport, thus, xylem water reflects source water. However, this correspondence does not always happen. Isotopic enrichment of xylem water has been found in several cases and has been either associated to “stem processes” like cuticular evaporation 1 and xylem-phloem communication under water stress 2,3 or to “soil processes” such as species-specific use of contrasting water sources retained at different water… Expand
