Improving the extraction and purification of leaf and phloem sugars for oxygen isotope analyses
Rationale: The oxygen isotopic composition (here shown as the δ18O value) of soluble sugars in leaves and phloem tissue holds valuable information about plant functions in response to climatic changes. However, δ18O analysis of sugars is prone to error, and thoroughly tested methods are lacking. Methods: We performed three experiments to test if sample preparation modifies the δ18O values of sugars. In experiment 1, we tested the effects of oven-drying versus freeze-drying, whereas in experiment 2 we focused on the extraction and purification of leaf sugars. In experiment 3, we investigated…
