Plants That Make Sound When They're Stressed

 Some studies have suggested that tomato plants may emit sounds at frequencies too low for the human ear to hear when they experience stress, such as water or nutrient deficiencies.

Similar to tomatoes, tobacco plants have been studied for their ability to produce ultrasonic sounds in response to various stress factors, including drought.

Research has shown that wheat plants can generate ultrasonic sounds during water stress conditions. These sounds are believed to be linked to the plant's structural changes.



Corn plants are known to produce clicking sounds when they experience water stress, which is associated with the formation and release of gas bubbles in their water-conducting vessels.



Some studies have indicated that grapevines, including the Cabernet Sauvignon variety, produce sounds when they experience water stress often in the ultrasonic range.

Certain species of cacti, including pincushion cacti, have been known to produce faint sounds or vibrations when exposed to physical disturbances or stress.

There have been reports of henbit plants producing audible sounds when they are subjected to stress. These sounds are relatively subtle & require sensitive equipment for detection.
