How Can Plant Growth Get Impacted By Noise Pollution?

Noise pollution has been increasingly studied in ecological research, with many studies showing its potential impact on biodiversity. Sound stimuli can influence germination rates and increase plant growth and development, improving the yield of some crops. Sound stimulation has been proven to switch on stress-induced genes or enhance genes related to disease resistance. However, there is a new age of research that shows human noise pollution affects the diversity of plants and trees. Plants can perceive and respond to sound cues from both biotic and abiotic sources, such as herbivores, pollinators, and noise pollution.

Biotic stress is one of the major causes compromising plant yield, quality of harvest, and survival. To prepare and tolerate such stresses, plants need to recognize and adapt to these changes. This article summarizes the effects of sound waves on plant growth and performance, focusing on frequency, intensity, and duration. It also discusses how sound can alter plant morphology.

Researchers have found that long-term noise pollution may discourage normal plant growth, with noticeable effects on habits years later. Persistent noise from natural gas wells in New Mexico disrupted birds that feed on and distribute pinyon seeds. Sound stimuli can influence germination rates and increase plant growth and development, improving the yield of some crops. However, excessive noise may cause unnecessary stress and disrupt the behavior of birds and other animals that plants rely on.

What are the effects of noise pollution?

Noise pollution has significant health effects on millions of people, including stress-related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity. The most common health effect is Noise Induced Hearing Loss (NIHL), but exposure to constant or high levels of noise can cause numerous other adverse health effects. To protect oneself from the harmful effects of noise pollution, individuals can use hearing protection such as ear plugs or ear muffs. There are various strategies for combating noise in various settings, including homes, schools, workplaces, and communities.

How does noise pollution impact development?

Noise pollution is a significant issue that can cause physical damage to the eardrum and inner ear hair cells, leading to temporary or permanent hearing loss. Exposure to more than 105 dBA can result in permanent hearing loss. Excessive noise exposure can also raise blood pressure, pulse rates, irritability, anxiety, mental fatigue, and interfere with sleep, recreation, and personal communication. Children living in areas with high noise pollution may suffer from stress and other problems, such as impairments in memory and attention span.

Noise pollution also impacts wildlife, as it interferes with an animal’s ability to attract mates, communicate, navigate, find food, or avoid predators. Marine animals, particularly those relying on echolocation, are particularly vulnerable to noise pollution. Much of the world’s oceans are polluted with chaotic sounds from ships, seismic tests, and oil drills. Naval sonar devices are some of the loudest and most detrimental sounds in the sea, causing mass strandings of whales and dolphins.

Do plants grow faster with sound?

Plants have a unique preference for music, with some genres promoting growth and others damaging. Roses, for instance, prefer violin music. Classical or jazz music can increase growth in plants, while harsh metal music can induce stress. Botanists, like Devendra Vanol of the Institute of Integrated Study and Research in Biotechnology and Allied Sciences in India, believe that plants can distinguish between different types of sound, including music genres, nature sounds, and traffic noise. This could be advantageous for plants to learn about their environment.

Reda Hassanien of China Agricultural University in Beijing found that sound waves significantly increased the yield of sweet pepper, cucumber, tomato, spinach, cotton, rice, and wheat. Additionally, sound treatment reduced pests such as spider mites, aphids, gray mold, late blight, and virus diseases in tomatoes. More studies are needed to understand how this works and what it could teach us about plants.

How does noise pollution affect nature?

Noise pollution negatively impacts wildlife, both on land and in the sea, causing physical and behavioral issues and increasing stress. Road traffic noise can hinder communication between frogs and songbirds, reducing reproduction and forcing them to flee their habitats. Underwater noise from shipping, energy production, and construction is also a concern. Research shows that hearing damage in whales can harm their ability to communicate and find food.

Road traffic remains the top source of noise pollution in Europe, with levels projected to rise due to urban growth and increased mobility demands. Rail, aircraft, and industry are other top sources of environmental noise pollution.

How does noise affect plant growth?

Sound waves have been found to be a potent plant stimulant and protectant, with various effects on plants. These include enhancing seed germination and plant growth by regulating growth hormones indole-3-acetic acid (IAA) and gibberellin, inducing plant defense responses against pathogens by activating plant defense hormones salicylic acid (SA) and jasmonic acid (JA), inducing abiotic stress tolerance by changing the elasticity and flexibility of the cell wall, and disrupting ripening by down-regulating ethylene biosynthesis and expression of signaling-related genes.

Sound treatment has also been used as a post-harvest delay agent, delaying fruit ripening by reducing ethylene production. Sound-treated tomatoes showed reduced ethylene production and delayed softening compared to the control. The expression of genes encoding transcription factors RIN and HB-1, which control the expression of ethylene-related genes, was also affected in tomato treated with sound stimuli. Exposure to 1 kHz sound induces tomato fruit to remain firm for longer.

Plant growth stimulants have been widely applied to alter plant growth, with sound-treated tomato showing 13. 2 increased yields compared to the control. However, high-frequency, high-decibel sound damages cells. Treatment with 5 kHz sound waves increased tiller growth and dry weight in wheat. The mechanism underlying how plant growth is improved by treatment with sound waves has not been intensively studied.

A simple explanation for this effect is that this treatment alters the levels of plant growth regulatory hormones. Sound exposure alters endogenous hormone levels in plants, with increased IAA and decreased ABA levels being major factors influencing the effect of sound waves on promoting plant growth. Other studies have shown that the levels of soluble proteins and soluble sugars increase in response to sound treatment, and soluble sugars can also be a factor in promoting plant growth as they can serve as an energy source.

Molecular studies support the notion that sound also induces plant growth promotion and seed germination. One possible mechanism underlying the plant growth-promoting effects of sound treatment is the enhancement of photosynthesis. Increased photosynthetic ability has been observed in strawberry and rice in response to sound treatment. Proteomics analysis showed that photosynthesis-related proteins were highly expressed at 8 hours after 250 or 500 Hz sound exposure in Arabidopsis.

Since sound energy induced secondary products can make chemical energy, sound treatment is thought to improve photosynthesis. These findings suggest that sound treatment can improve the quality of vegetable and fruit crops.

How does pollution affect plant growth?

Air pollution can cause damage to plants in various ways, including visible necrotic lesions or gradual leaf yellowing or chlorosis. Plants may experience reduced growth and may be killed outright, but usually do not succumb until they have suffered recurrent injury. Ozone, the main pollutant in the oxidant smog complex, has been observed in the Los Angeles area since 1944 and has been reported in many areas throughout North America, including Ontario.

Ozone levels vary significantly during the growing season, particularly in July and August. Sensitivity to damage is often used, while resistant species include endive, pear, and apricot. Ozone symptoms typically appear on the upper surface of affected leaves, appearing as flecking, bronzing, or bleaching of leaf tissues. While yield reductions are usually with visible foliar injury, crop loss can also occur without any sign of pollutant stress. Some crops can sustain visible foliar injury without adverse effect on yield.

How does noise pollution affect the plants?

Noise pollution is affecting the landscape of plants and trees, which rely on noise-affected animals to pollinate and spread their seeds. Some plants perform worse in noisy areas, while others seem to perform better depending on the changes in their surrounding creatures. The ripple effects can be long-lasting, especially for trees, which take decades to grow from seedlings into adults. The results may apply to any ecosystem where animals are affected by noise. Most literature on noise impacts has focused on single species’ communication issues.

What are the 10 effects of noise pollution?
