Abstract

<p>This paper reviews the research on the detection of elastic waves generated from plants by the Acoustic Emission (AE) method during the 54 years from 1966 to 2019, and summarizes the future issues regarding the use of AE methods in agricultural production. Nowadays, AE generation behavior and AE characteristics of energy and frequency can be acquired with high precision. So, the AE method is useful for evaluating vulnerability of trees and diagnosing the precise growth of agricultural products. Future research topics include networking of environmental, management and biometric information to contribute to the spread of smart agriculture. It is necessary to establish a method for processing a large amount of acquired waveform data and an accurate method for discriminating AE waves with different waveform features. In addition, it is necessary to elucidate the bubble generation mechanism in the vessel and to examine the relationship with the vessel structure, plant physiology and AE characteristics.</p>
