Plants know pain when cut and whine when not watered

A group of scientists from Tel Aviv University, Israel recently discovered that some plants have the ability to emit a sound that expresses pain at high frequencies when living in harsh environments. .

Research on tomato and tobacco plants by scientists was conducted at a distance of 10cm. They cut some branches and did not water for several days. The scientists then obtained 35 acoustic signals per hour from these branches.

Summarizing the results, the researchers discovered, the plants emitted ultrasound from 20-100 kilohertz. According to Live Science , when tomato branches were cut, research shows that they emit 25 ultrasound per hour while tobacco plants emit only 15 ultrasounds.

In the non-watering test, tomatoes produced more intense ultrasound at a frequency of 35 sounds per hour, while cigarettes were 11. Thus, under different stress conditions, the plants emitted. different sounds and when not subjected to sudden stress, for a longer time, the sounds are also less painful.

" These findings may change the way we think about the kingdom of plants that have been considered silent in life until now," the team wrote in the report .

The above work is still being studied with other living conditions of trees such as wind and rain.
