New research claims: Noise pollution stops the growth of plants

The lion’s effect on animals has been proven in numerous scientific studies. There was also no doubt that, as a result of the effect on organisms, plant pollination is disrupted, and the plant world is affected. The direct impact of shove pollution on plant development is revealed in a recent study published in the journal Basic and Applied Ecology. The effects of lions on plants have been studied by Ali Akbar Ghatbi Rwandi, a zoologist at Tehran’s Shahid Bahshti University.

In his lab, the Iranian scientist grew marigold (French marigold) and scarlet sage, two plants commonly found in urban areas. They were divided into two groups after being grown in the same environment for two months. For 16 hours a day, one group was subjected to the 73 decibels of Tehran’s busy traffic. The other group was kept in a segregated area. The donors’ samples were taken for study after 15 days.

It had an effect on pedestrians caught in the middle of the traffic jam. It was clear from the analysis of their leaves that they were in pain. High levels of chemicals like hydrogen peroxide and malondialdehyde in the plants indicated that they were stressed. Scarlet sage samples among lions had twice as many melandialdehydes as plants growing in a calm environment, and French marigold samples had three times as many.

The researchers discovered that the levels of hormones that promote healthy growth and development in plants kept in lions were also significantly reduced. Jasmanic acid and abscisic acid, two stress hormones, were found to be higher. These hormones were created to protect against insect attack as well as to cope with alkaline soil and extremely low temperatures. The weight of the leaves of the plants in the less polluted sample was also lower.

Plants do not have ears, but they are all affected by noise vibrations.

Plants’ stress responses to traffic vibrations are similar to those in drought-famine conditions or when soils are alkaline or contaminated with heavy metals, according to studies. But it does happen. Do all types of noise pollution have the same effect on all species?

Where does the forest or nature remain silent if there is a lot of traffic in the cities? The storm’s harshest effects are felt in the high mountainous grasslands. The roaring waterfalls are also surrounded by vegetation. According to scientists, some plant species may have evolved a defence mechanism to deal with the lion. For the time being, it remains a mystery.
