Scientists have proposed that the plant wall project can not only purify the air, but also beautify the environment.

Recently, according to foreign media reports, scientists plan to build plants into a new green air monitoring system. Once harmful gases are sensed in the air, plants can change color or emit fluorescence to remind people of changes in the surrounding gas environment.

Rana Abudayyeh, a professor at the University of Tennessee in the United States, said that when Neil and his wife explored the issue of plant genetic improvement, they had an inspiration and thought that they could modify some genes of plants to make plants more sensitive. Once exposed to harmful gases, corresponding defense measures would be taken inside the body. At this time, there will be some changes on the outside of the plant, and by observing the changes in the plant, people can realize that the air quality is declining in their environment.

In Rana Abudayyeh's vision, a household "plant wall" can be built, which has two special functions. The first effect is to filter the air. The "plant wall" is made up of all kinds of plants, and most of the gas passes through the plant stomata and enters the cells. After the plant cells absorb and filter the foreign gas, some of the gas will be released, and the gas filtered by the plant cell is naturally cleaner than the original gas, which can create a good gas environment for people.

Second, after genetic modification, plants are more sensitive. Once they come into contact with harmful gases or viruses, plants will change color. In preliminary tests, Rana Abudayyeh placed the "plant wall" in an environment full of mold, flu virus or mixed with volatile compounds. In different environments, the "plant wall" showed discoloration or glaring fluorescence.

Neal Stewart, co-author of the study, agrees with Professor Rana Abudayyeh and Mr. and Mrs. Donnell. Neal Stewart said that household plant landscapes or potted plants can be found everywhere, most of which have a beautiful and faintly refreshing environment. It would be better to improve plant genes so that plants have both ornamental and practical value.

In addition, Neal Stewart said that in all kinds of home decorations, plant home decorations are the most environmentally friendly and most effective. Plant home decoration can add a touch of green to the room, give people a sense of vitality, and help people reduce stress and annoyance. If a new type of "plant wall" with multiple effects is launched in the future, it is believed that there will be an endless stream of customers.
