Figure 6. — Xylem tension (relative to the atmosphere) monitored by the xylem pressure probe during experiments parallel to tracer applications. A, Application via the cut stem. The number sign (#) indicates cutting of the stem under water. B, Application via a microcapillary. The downward arrow indicates insertion of the application microcapillary, and the upward arrow indicates withdrawal of this microcapillary. The horizontal dashed lines in A and B mark the saturation water vapor pressure (0.0977 MPa). C, Percentage loss in tension via the cut stem (n = 6; mean ± sd) and with capillary application (n = 4).
