Plant water relations in lychee: diurnal variations in leaf conductance and leaf water potential

open access: yesAgricultural and Forest Meteorology, 1986
Abstract Diurnal variations in leaf conductance and leaf water potential were investigated in 6-year-old lychee trees (Litchi chinensis sonn. cv. Bengal) during the dry season in subtropical Queensland, Australia. Leaf conductance and leaf water potential fell from 0.56 mol m−2 s−1 and -0.1 MPa in the morning to 0.08 mol m−2 s−1 and -1.0 MPa ...

An Error in the Calibration of Xylem-water Potential against Leaf-water Potential

Journal of Experimental Botany, 1971
An error occurs in the calibration of xylem pressure potential (Ta;) against leaf-water potential (Tir) when the calibration is made using plant material in which the water stress has been induced artificially after excision. The imposition of water stress after excision affects the T'a: determination more than it affects Tw, consequently the ...

Effect of Excision on Leaf Water Potential

Journal of Experimental Botany, 1984
Improvements of thermocouple hygrometrie techniques for in situ leaf water potential measurement in the field now allows for continuous monitoring of water potential in response to an external perturbation, such as leaf excision. Using Citrus jambhiri plants, measured leaf water potentials of completely excised leaf portions immediately increased when ...
