- Water in plant xylem is often superheated, and therefore in a meta-stable state. Under
certain conditions, it may suddenly turn from the liquid to the vapor state. This cavitation
process produces acoustic emissions. We report the measurement of ultrasonic acoustic
emissions (UAE) produced by natural and induced cavitation in corn stems. We induced
cavitation and UAE in vivo, in well controlled and reproducible experiments, by irradiat-
ing the bare stem of the plants with a continuous-wave laser beam. By tracing the source
of UAE, we were able to detect absorption and frequency ltering of the UAE propagat-
ing through the stem. This technique allows the unique possibility of studying localized
embolism of plant conduits, and thus to test hypotheses on the hydraulic architecture of
plants. Based on our results, we postulate that the source of UAE is a transient cavity
oscillation" triggered by the disruptive eect of cavitation inception.
