In xylem, NSC are mostly stored as soluble sugars and starch in radial and axial parenchyma. The multi-functional nature of xylem means that cells possess several functions, including water transport, storage and mechanical support. Little is known about how NSC impacts xylem multi-functionality, nor how NSC vary among species and climates. We collected leaves, stem and root xylem from tree species growing in three climates and estimated NSC in each organ. We also measured xylem traits linked to hydraulic and mechanical functioning. Data description The paper describes functional traits in leaves, stems and roots, including NSC, carbon, nitrogen, specific leaf area, stem and root wood density and xylem traits. Data are provided for up to 90 angiosperm species from temperate, Mediterranean and tropical climates. These data are useful for understanding the trade-offs in resource allocation from a whole-plant perspective, and to better quantify xylem structure and function related to water transportation, mechanical support and storage. Data will also give researchers keys to understanding the ability of trees to adjust to a changing climate. specialized Angiosperms Non-structural carbohydrates Fibers Functional traits Mediterranean Parenchyma Root Temperate Tropical Vessels 076 021 BMC Research Notes 15 1 251 [3 p.] 2022 https://www.documentation.ird.fr/hor/fdi:010085401 10.1186/s13104-022-06136-7 [F B010085401] https://www.documentation.ird.fr/hor/fdi:010085401 https://horizon.documentation.ird.fr/exl-doc/pleins_textes/2022-09/010085401.pdf IRD - Base Horizon / Pleins textes 2022-09-02 2025-02-24 fdi:010085401 fre
