Data for Tree-ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring

Data associated to manuscript Fernández-de-Uña L., Rathgeber C.B.K., Pérez-de-Lis G., Andrianantenaina A.N., Cuntz M. (2026) Tree-ring structure determines the temporal coordination between xylem growth and the gain in hydraulic conductivity in the outermost ring. New Phytologist. The dataset includes intra-annual data of current-year ring basal area increment (BAI), conductive area (CA), theoretical hydraulic conductivity (Kh) and specific conductivity (Ks) and the ratio functional:total CA, Kh and Ks. Values after the cessation of xylem enlargement (BAI) and maturation (CA, Kh and Ks) are the median of the values measured after that date.
