Multiple Choice

J.A.Milburn and R.P.C.Johnson developed an acoustic method for detecting cavitation in plants.This involves "listening" for characteristic clicks produced during air-bubble formation,using sensitive microphones and amplifiers.In one experiment with the castor bean plant (Ricinus communis) ,they detached leaves by cutting the petioles and subjected them to various treatments.Which of the following would be least likely to be observed in such an experiment?

• A)as the leaf is allowed to wilt,recording many clicks that approximately equal the estimated number of vessels in the cut petiole
