S. Korean researchers prove plants react to human activity Updated: 2021-01-17 09:40:03 KST

Scientists in South Korea have published new research on how plants use chemical signals to signal to other plants about their health.

The COVID-19 pandemic has reshaped our lives in many ways.
Now, more people are growing plants at home to find comfort and help ward off the corona blues.
Some explain that seeing plants grow gives them something to be happy about amid these difficult times. They also believe that plants react to their behavior.
"I watered it constantly after returning from a brief trip. And I already see it grew a lot. It gives me strength, and I learned that growing plants with continuous care and love can make a big difference."
This seemingly intuitive opinion is backed by a recent scientific study conducted by South Korea's Rural Development Administration.
Scientists took some leaves, tore them into small pieces, and then put them into separate plastic bags each sealed with air inside.
Each bag was then attached to a special glass that was connected to a healthy plant.
The researchers found that the ripped leaves produced an average of twenty-three percent of a certain type of chemical, which is known to help them communicate with other plants.
The scientists concluded that the generated chemical was a signal for help.
"We learned that whether people take extra care of their plants or neglect them, they react to the activities practiced upon them."
This scientific finding is expected to pave the way for more studies on plants' reactions to various human behaviors.
