Abstract
The loading induced cavitation near the AE sensor attached on miniature tomato was tried to improve the detectability of AE by the compression loading and unloading of the stem via the AE sensor. The AE occurrence rate was rapidly increased after the loading and unloading test. The waveforms of the detected AE showed the various frequency patterns like those generated by the spontaneous cavitation events. These results suggested that the AEs were induced by the loading and unloading test. It is expected that such a technique contribute to improve accuracy of estimation of the embolism risk of tomato plants.
