Essential to Buddhist thought . . .
Amen,
Nice to see science is finally catching up to what religions have known for 1000s of years
When does hot become cold?
Plants can emit certain sounds and chemicals when stressed or damaged, which can be interpreted as a form of communication or distress signal. Hereβs a summary of what studies have found:
-
Chemical Signals: When grass and other plants are cut, they release volatile organic compounds known as green leaf volatiles (GLVs). These chemicals serve multiple purposes, including helping to heal the plantβs physical wounds, deterring herbivores, and signaling to other plants and organisms about the threat [β] [β].
-
Ultrasonic Sounds: Research also indicates that plants may emit ultrasonic squeals when stressed. Studies involving tomato and tobacco plants found that these plants could emit sounds in the ultrasonic range (20-150 kHz) when subjected to physical harm or drought conditions. These sounds are not audible to human ears but could be detectable by other organisms, such as insects or animals, that respond to ultrasonic frequencies [β].
-
Plant Response to Damage: The smell of freshly cut grass, which many people find pleasant, is actually a distress signal from the grass, indicating it is trying to save itself from the injury inflicted by mowing or cutting [β].
