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 ...

Root Pressure and Leaf Water Potential

Science, 1966
Measurements with thermocouple psychrometers were made of the water potentials of leaves from sunflower and pepper plants which had stood overnight in the dark in nutrient solutions containing carbowax. Similar measurements on the solutions showed that they had lower water potentials than the leaves, although the plants were measurably transpiring ...

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

Agricultural 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 ...

Relation of Soybean Leaf Water Potential to Soil Water Potential¹

Agronomy Journal, 1974
AbstractEstimation of plant water potential is a possible aid in irrigation scheduling. This work examined the relation of maximum and minimum soybean (Glycine max (L.) Merr.) leaf water potential to soil water potential. Maximum readings were taken near sunrise and minimum readings were taken between 1300 and 1500 CDT.
