Scientists have discovered through research that plants have phenomena similar to "happiness, anger, sadness, and joy".
"Happy". Two college students in the United States placed a tape recorder next to the zucchini growing in two rooms, and played intense rock music and elegant ancient music to them respectively. Eight weeks later, the vines of the zucchini that "listened" to classical music climbed toward the tape recorder, and one of them even wrapped its branches around the tape recorder; while the vines of the zucchini that "listened to" rock music climbed away from the tape recorder. He seemed to be trying to avoid the loud noise. As you can clearly see from this experiment, plants respond well to soft classical music.
"Anger". Baxter, an American lie detector expert, conducted an interesting experiment: He first placed two plants side by side in the same room, and then found six people wearing masks and wearing the same clothes. He asked one of them to stand in front of a plant. The face of a plant destroys another plant. Since the "criminal" was obscured by the mask, neither others nor Baxter himself could tell who the "criminal" was. Then, the six people walked past the surviving plant one by one. When the real "criminal" came forward, the plant left an extremely strong signal on the recording paper through the instrument connected to it, seeming to shout "He is the murderer!" It can be said that this of the plant This reaction is somewhat similar to human anger.
"Sorrow". Baxter also conducted another experiment. He connected the electrode of the lie detector to a leaf of a dracaena tree, and immersed another leaf in a cup of hot coffee. The instrument recorded a weak response. Then he decided to burn the leaf with fire. As soon as he lit the flame, a strong signal reaction immediately appeared on the recording paper, as if crying: "Please let this leaf go, it has been burned to the point of discomfort, how can you bear to burn it again?"
Some biologists in the Soviet Union have conducted similar experiments: after putting the roots of plants into hot water, the desperate "crying" of the plants immediately came out of the instrument.
"Happiness". Some Japanese biologists have successfully used instruments to "talk" to plants. When they "confess" and "love" to the plants, the plants will send out fast-paced and harmonious signals through the instruments, which are as beautiful as singing. There is a biologist in India who asked people to play beautiful "raga" music on impatiens in the garden for 25 minutes every day for 15 consecutive weeks. He found that the leaves of impatiens that had "listened" to music were on average 70% longer than the leaves of ordinary flowers, and the average height of the flowers also increased by 20%. The development of modern science and technology continues to raise some new topics for people, such as how to explain the "emotion"-like phenomena mentioned above about plants? According to our existing knowledge, we can only attribute this kind of phenomenon to the stress of plants, but to explain the mechanisms of various phenomena, I am afraid that future generations will still need to continue to explore.
