Acoustic emissions (AE) could be used as an indicator of plant water stress as “speaking plant”. The objective of this study was to observe the AE of tomato plant and to analyze the relationship between AE and plant water consumption associated with transpiration. Three glasshouse experiments were conducted with potted tomato plants. The AE, transpiration rate and “the plant transpiration transfer coefficient (hat)” as an indicator of plant water stress level were determined with hat being calculated based on sunlit leaf temperature, temperature of an artificial leaf without transpiration (hereafter,referred to as “non-transpiration leaf temperature”) and air temperature. The results showed that the daily patterns of the AE varied depending on the water stress level, which was indicated by hat. Under mild or moderate water stress (hat ≦0) conditions, the AE increased with the decrease in the amount of soil water but decreased with the decrease in the amount of soil water under severe water stress conditions (0
