Sap Flow and Stem Respiration

2010
The effects of seasonal flooding on stem xylem flow and carbon release were investigated on common tree species of the Amazonian floodplain forests locally known as Varzea. The annual flooding lasts several months, reaches five to eight meters and drives the phenology of most forest species.

Pressure and Flow of Sap in the Maple

The American Naturalist, 1906
1. The source of pressure for the bleeding of trees in spring seems to be localized in different portions of the plant in different species. 2. Trees may be roughly classified into two groups in this regard: (a) those in which the source is mainly in the trunk and branches. These, as for example the maple, bleed early in the season.

A new technique of measuring sap flow that accurately measures a wide range of sap flow rates

Accurate estimation of sap flow is vital for plant models and significantly impacts existing management policies, particularly when scaling from the plant level to plot levels. The heat pulse method (HPM) is widely used for measuring sap flow in plants because of its added benefits compared to other traditional methods.

ENGINEERING A SAP FLOW SENSOR FOR IRRIGATORS

Acta Horticulturae, 2013
Sap flow sensors designed for irrigators – as distinct from scientific researchers – must be inexpensive and robust, simple to install and interpret, and able to advise a grower when the crop is becoming water stressed. Modern growers also expect data to be delivered to them wherever they may be and whenever they want it, which impacts directly on the ...

Measurement of Sap Flow by Heat Transfer

Nature, 1958
IT has been assumed by those who have used a pulse of heat as an indicator to measure the rate of flow of sap in trees1 that the speed of the sap is identical with that of the heat pulse.
