Scientists have long discovered that plants communicate with each other, especially similar plants.

So, how do plants achieve "dialogue"? American scientists first discovered that some plants, such as willows, warn their neighbors of tooth worm invasion by stimulating pheromones, which are odorous.

Recently, German scientists further confirmed that some plants can "speak" through high-frequency sounds, just because the frequency is too high for human ears to hear; Other plants transmit information through very weak light, of course, simple language-this weak light is difficult for human eyes to detect, but instruments can detect it.

The saying that "plants also have language" explains why the leaves of the same kind around an albizzia tree will be bitter soon after it is eaten by wild sheep, and why after an oak tree is cut down, the rest will produce more seeds like a tree, which seems to make up for the loss and allow the race to multiply.

Professor Herbert Weitz, a German biologist, recently claimed that he had "decoded" the "languages" of more than 65,438+00 kinds of trees, including acacia and phoenix tree. He even pointed out that different tree species have different "language styles", such as trees, beeches and pine trees, which are more interesting, while Pinus massoniana is relatively simple.

From this perspective, we originally thought that the "peace" in the forest was actually not calm; Pheromones are not only inaudible to the nose of the person who gives the alarm, but also sound and light-just invisible to the ear and naked eye.

Scientists also optimistically predict that in less than 20 years, all the "languages" of plants will be "deciphered", so that forests will be better protected and pests and diseases will be better controlled.
