Plants Make Sounds Especially When Stressed, Study Reveals

"When tomatoes are not stressed at all, they are very quiet," Hadany informed.Â
Water-deprived plants made sounds before showing signs of dehydration, and the frequency of these sounds peaked after five days without water before decreasing when the plants were completely dry.
In addition, the type of sound produced varied depending on the stressor. The researchers used a machine learning algorithm that could accurately distinguish between dehydration stress and stress caused by cutting, as well as tell whether the sound was coming from tomato or tobacco plants.
While the study focused primarily on tomato and tobacco plants due to ease of cultivation and standardization in the lab, the research team also recorded sounds from a variety of other plant species.
"We found that many plants – corn, wheat, grapes, and cactus plants, for example, make sounds when stressed," Hadany stated.Â
