Abstract:
In 22-yr old Shamouti orange trees, soil water potential in the upper 0.6m of the root zone was reduced from -0.01 to -0.87 MPa by withholding water for a period of 45 days. Leaf conductance was dominantly controlled by soil water potentials lower than -0.02 MPa.-from AuthorsDiv of Agric Meteorology, ARO, The Volcani Center, Bet Dagan, Israel.English
