Xylem tension was experimentally imposed by centrifugal force to assess the stability of negative pressures within the xylem and the estimation of those pressures with a pressure chamber. Balancing pressure measurements of leaves attached to a spinning branch at the axis of rotation closely agreed with tensions calculated from the rotational velocity. This agreement demonstrates that the xylem is capable of sustaining large negative pressures and directly validates the balancing pressure…

The physical basis and evidence in support of the cohesion-tension theory of the ascent of sap in plants are reviewed. The focus is on the recent discussion of challenges to the cohesion-tension
Water ascent in plants: do ongoing controversies have a sound basis?
New evidence for large negative xylem pressures and their measurement by the pressure chamber method
Pressure probe measurements have been interpreted as showing that xylem pressures below c. -0.4 MPa do not exist and that pressure chamber measurements of lower negative pressures are invalid. We
Direct measurement of xylem pressure in leaves of intact maize plants. A test of the cohesion-tension theory taking hydraulic architecture into consideration
The hydraulic architecture model could predict all observed changes in water flow rate and xylem and measured the cavitation threshold for oil- and water-filled pressure probes and provide some suggestions for improvement.
Diurnal changes in xylem pressure and mesophyll cell turgor pressure of the lianaTetrastigma voinierianum — the role of cell turgor in long-distance water transport: a reply
SummaryFrom equilibrium thermodynamics an equation is given to show that in a liquid negative pressures (tensions) are physical reality and may reliably be recorded from any point of the aqueous
The transmission of gas pressure to xylem fluid pressure when plants are inside a pressure bomb.
It is argued that the non 1:1 relationship in the positive pressure range does not invalidate the Scholander pressure bomb method of measuring xylem pressure in plants because Px never reaches positive values during the determination of the balance pressure.
Use of centrifugal force in the study of xylem cavitation
Two methods were evaluated for using centrifugal force to measure the occurrence of cavitation as a function of negative pressures in xylem. The general protocol was to measure the hydraulic
Evaluation of a new centrifuge technique for rapid generation of xylem vulnerability curves
A new technique for generating xylem cavitation and vulnerability curves was evaluated. The centrifugal force was used to lower the negative pressure in a xylem segment and to induce a positive
Continuous measurements of water tensions in the xylem of trees based on the elastic properties of wood
Abstract. According to the cohesion theory for the ascent of water in vascular plants, significant tensions should develop in the water columns of transpiring trees. These tensions cause small but
Hydrogel Control of Xylem Hydraulic Resistance in Plants
The existence of an ion-mediated response breaks the long-held paradigm of the xylem as a system of inert pipes and suggests a mechanism by which plants may regulate their internal flow regime.


Sap Pressure in Vascular Plants
A method is described which permits measurement of sap pressure in the xylem of vascular plants, and finds that in tall conifers there is a hydrostatic pressure gradient that closely corresponds to the height and seems surprisingly little influenced by the intensity of transpiration.
An Impasse in Plant Water Relations
Balling and Zimmermann [Planta 182 (1990), 325–338] used a pressure probe to measure directly negative pressures in the xylem of transpiring plants. They obtained data that challenge the standard
A New Theory for the Ascent of Sap—Cohesion Supported by Tissue Pressure
A new theory is proposed that the driving force and the transmission of the force are the same as in the Cohesion Theory, but the operating pressure of the xylem is raised into a stable range by compensating tissue pressures pressing upon the tracheary elements.
A critical comparison of the pressure‐probe and pressure‐chamber techniques for estimating leaf‐ceil turgor pressure in Kalanchoë daigremontiana
The aim of the present study was to test the accuracy of the pressure-chamber technique as a method for estimating leaf-cell turgor pressures. To this end, pressure-probe measurements of cell turgor
Mechanisms of long-distance water transport in plants: a re-examination of some paradigms in the light of new evidence
According to the widely accepted Cohesion Theory, water is pulled by transpiration from the roots through the xylem to the leaves. It is believed that this process results in the development of large
The decrease in hydrostatic pressure generated by octopus suckers adhering to wettable and non-wettable surfaces was measured using a flush-mounted miniature pressure transducer. The cavitation
II. On the ascent of sap
Strasburger’s experiments have eliminated the direct action of living protoplasm from the problem of the ascent of sap, and have left only the tracheal tissue, as an organised structure, and the
Comparison of water potentials measured by in situ psychrometry and pressure chamber in morphologically different species.
In situ psychrometers are suitable for following dynamic changes in leaf water potential, but should be used with caution on leaves with low epidermal conductances, as pressure-volume studies showed that less water was expressed from distal than proximal leaflets when the whole leaf was slowly pressurized.
