Xylem cavitation in plants is thought to be caused by a loss of adhesion at the conduit wall surface because a rupture in the body of the water column was implicitly ruled out by an experiment by Lyman J. Briggs with Z-tube capillaries. However, Briggs reported a drastic increase in cavitation pressure of water below 5 degrees C which, if it were also true in xylem conduits, would suggest that water transport in plants could be limited by water cohesion at low temperature. In this study we have… CONTINUE READING
