Hence, there exist an opportunity to measure the water potential in the stem by embedding a sensor in the stem of the tree.
WebStem water potential is the direct measure of the tree water status by measuring the water tension within the plant (MPa). It is traditionally used as the reference to compare against other water status indicators [6]. Currently, the main limitation of Ystemis the time required to make measurements. WebUsing microchip technology, we have developed a miniature tensiometer (microtensiometer) small enough to be embedded in the vine stem, where it can measure stem water …
