Changes in leaf hydraulic conductance correlate with leaf vein embolism in Cercis siliquastrum L. Received: 8 January 2003 / Accepted: 6 March 2003 / Published online: 16 May 2003 Springer-Verlag 2003
Abstract The impact of xylem cavitation and embolism on leaf (Kleaf) and stem (Kstem) hydraulic conductance was measured in current-year shoots of Cercis siliquastrum L. (Judas tree) using the vacuum chamber technique. Kstem decreased at leaf water potentials (YL) lower than 1.0 MPa, while Kleaf started to decrease only at YL
