Wang et al. (2022), Data from: Lianas have a faster resource acquisition strategy than trees: belowground evidence from root traits, phylogeny, and the root economics space The data includes the root morphological (root diameter, specific root length, root tissue density), architectural (root branching ratio), anatomical (cortex thickness, stele diameter) and chemical traits (root nitrogen concentration, ratio of carbon to nitrogen), as well as the percentage of mycorrhizal colonization of 69 lianas. Abbreviations of the data: RD, root diameter (mm); SRL, specific root length (m g-1); RTD, root tissue density (g cm-3); RN, root nitrogen concentration (mg g-1); RCN, ratio of carbon to nitrogen; BR, root branching ratio; CT, cortex thickness (μm); SteleD, stele diameter (μm); Myc, mycorrhizal colonization (%);
