Relations between water content, potential and permeability in stems of conifers.
Plant, Cell and Environment, 1982Abstract. The influence of sapwood water content on the conductivity of sapwood to water was measured on stem sections of Pinus contorta. A reduction in relative water content from 100 to 90% caused permeability to fall to about 10% of the saturated value.

The Relationship between Leaf Water Potential and Stem Diameter in Sorghum
Agronomy Journal, 2001Leaf water potential (ψl) represents a good indicator of the water status of plants, and continuous monitoring of it can be useful in research and field applications such as scheduling irrigation. Changes in stem diameter (Sd) were used for monitoring ψl of pot‐grown sorghum [Sorghum bicolor (L.) Moench] plants in a glasshouse.

A new method of measuring water potential in tree stems by water injection
Plant, Cell and Environment, 1981Abstract. A new method of measuring xylem water potential in the stems of trees is described. The flow rate of water injected into the xylem at two or more known pressures is measured. The xylem water potential is derived either graphically from the relationship between flow rate and applied pressure, or from the solution of simultaneous flow equations.

Midday Stem Water Potential as a Basis for Irrigation Scheduling
5th National Decennial Irrigation Conference Proceedings, 5-8 December 2010, Phoenix Convention Center, Phoenix, Arizona USA, 2010There has been great progress in using midday stem water potential (SWP, measured with the pressure chamber) as a basis for irrigation scheduling, particularly for the management of regulated deficit irrigation (RDI) in trees and vines. In almonds, RDI is used during a one month period when the hulls are splitting, in order to reduce hull rot and ...

Measurement of Stem Water Potential of Young Plants Using a Hygrometer Attached to the Stem
Journal of Experimental Botany, 1982A simple method was developed for the continuous non-destructive measurement of plant stem water potential. It consists of exposing a small section of stem vascular tissue and attaching to it a standard commercially available dewpoint hygrometer. Excellent agreement was found between water potential determined by this method, and that measured with a ...

Patterns of stem water potential in field grown potatoes using stem psychrometers
Potato Research, 1997The first large scale outdoor measurements of potato (Solanum tuberosum L.) stem water potential (SWP) usingin situ temperature-corrected stem psychrometers were performed on three cultivars common to Ontario, Canada (Atlantic, Monona and Norchip).

The Relationship between Stem Diameter and Water Potentials in Stems of Young Cabbage Plants
Journal of Experimental Botany, 1984Continuous measurements were made of stem shrinkage, stem water potential (fj and transpiration rate (T) in young, pot-grown cabbage plants subjected to cycling evaporative demands. Sequences of increasing evaporative demands induced increases in T and decreases in both Ws and stem diameter and conversely, whenever evaporative demand decreased, T ...

Simultaneous measurements of tomato fruit and stem water potentials using in situ stem hygrometers
Canadian Journal of Botany, 1989Simultaneous measurements were made of the water potentials of the stem and fruit of intact tomato plants (Lycopersicon esculentum Mill. var. Heinz 2653) using in situ temperature-corrected stem psychrometers. Water potential of the fruit remained consistently lower than the water potential of the stem except when the plant had been subjected to ...
