  abstract = {{P}remise {N}onstructural carbohydrates ({NSC}s) play a key role in tree performance and functioning and are stored in radial and axial parenchyma ({RAP}) cells. {W}hether this relationship is altered among species and climates or is linked to functional traits describing xylem structure (wood density) and tree stature is not known. {M}ethods {I}n a systematic review, we collated data for {NSC} content and the proportion of {RAP} in stems for 68 tree species. {T}o examine the relationships of {NSC}s and {RAP} with climatic factors and other functional traits, we also collected climatic data at each tree's location, as well as wood density and maximum height. {A} phylogenetic tree was constructed to examine the influence of species' evolutionary relationships on the associations among {NSC}s, {RAP}, and functional traits. {R}esults {A}cross all 68 tree species, {NSC}s were positively correlated with {RAP} and mean annual temperature, but relationships were only weakly significant in temperate species and angiosperms. {W}hen separating {RAP} into radial parenchyma ({RP}) and axial parenchyma ({AP}), both {NSC}s and wood density were positively correlated with {RP} but not with {AP}. {W}ood in taller trees was less dense and had lower {RAP} than in shorter trees, but height was not related to {NSC}s. {C}onclusions {I}n trees, {NSC}s are stored mostly in the {RP} fraction, which has a larger surface area in warmer climates. {A}dditionally, {NSC}s were only weakly linked to wood density and tree height. {O}ur analysis of evolutionary relationships demonstrated that {RAP} fractions and {NSC} content were always closely related across all 68 tree species, suggesting that {RAP} can act as a reliable proxy for potential {NSC} storage capacity in tree stems.},
