Acoustic Emissions from Drought-Stressed Plants Contain Species-Specific Information

Hadid R, Svensson L, O'Brien T

Summary

9.5/10

Stressed plants make unique ultrasonic sounds that predict collapse 48 hours before wilting is visible.

Key Findings

1

Species ID from sound alone: 94% accuracy

2

Acoustic prediction of hydraulic failure 48h early

3

Click frequency tracks xylem cavitation

description

Original Abstract

Ultrasonic recordings from 6 crop species under drought reveal species-specific acoustic signatures. Random forest classifiers distinguished species with 94% accuracy from acoustic data alone. Click frequency correlated with xylem cavitation events and predicted hydraulic failure 48 hours before visual wilting.

Tomato

The tomato is a plant whose fruit is an edible berry that is eaten as a vegetable. The tomato is a member of the nightshade family that includes tobacco, potato, and chili peppers. It originated from western South America, and may have been domesticated there, in Mexico, or in Central America. Th...
