Scientists from Tel Aviv University discovered that some plants (tomatoes and tobacco) make ultrasonic sounds when under stress, similar to the bursting of bubble wrap. These release reports Science News with reference to the results of the study.
The scientists placed ultrasonic microphones near living plants to see if the plants could produce vibrations that circulated through the air. It turned out that with a lack of moisture, tomatoes emit about 35 ultrasonic clicks per hour. Plants cut from the stem were less noisy, and tobacco plants even less rattling. This was not observed at sufficient moisture level and when the plants were not cut.
It has been noted that the sounds made are too loud for humans, but dogs can hear. At the same time, each plant species had a recognizable “voice”.
The researchers believe the data could help agriculture monitor moisture levels in plants.
Toxicologist, creator of “Kutushov Symbionts” Mikhail Kutushov, in conversation with socialbites.ca saidthat tomatoes, potatoes and onions should not be stored in the refrigerator – they darken faster, undesirable chemical reactions begin in them.
