Plants can react to music because of the sound vibrations, which can affect their growth and health by altering their metabolism and promoting the circulation of nutrients and water in their cells.
The sound vibrations caused by music travel through the air and directly touch the surface of plants. These vibrations propagate within plant tissues, where they influence certain specific cellular processes. For example, plant cells can detect these vibrations through mechanoreceptors, which are types of sensors that respond to mechanical stimuli. They then modify their behavior by regulating growth or the synthesis of useful hormones differently. Specifically, some studies show that vibrations open small channels in cell membranes, thereby facilitating the exchange of minerals and nutrients essential for growth. Similarly, these mechanical stimuli can encourage the production of defense molecules that help the plant better withstand stress or diseases.
Certain sound frequencies have a surprising effect on plants. For example, studies suggest that sounds between 125 and 250 Hz promote growth and strengthen roots. Regular rhythms, such as those found in certain classical or traditional music, seem to stimulate the opening of stomata, those tiny pores that allow plants to breathe and absorb CO₂. Conversely, sounds that are too high-pitched or too intense (above 1000 Hz) can sometimes cause stress and hinder their growth. In short, it's not certain that metal is the best choice to please your cactus.
Listening to certain types of music can accelerate the growth of some plants. Several experiments even show that plants exposed to classical music or soft sounds develop stronger roots and more vigorous foliage. However, be cautious; this effect really depends on the style of music chosen: for example, sounds that are too loud or aggressive, like some very dynamic musical genres, could have the opposite effect, leading to a slowdown in growth or even stress in plants. Soft music acts somewhat like a gentle sound stimulation that could improve nutrient absorption, make plants more resistant to diseases, or even enhance their natural ability to defend against certain pests. Even though the precise reaction varies depending on the species and listening conditions, the idea of using music to cultivate hardier and healthier plants has intrigued many amateur gardeners and researchers for years.
Plants perceive sound vibrations through their cell membranes, which are sensitive to mechanical stimuli. When they capture these vibrations, signals travel through an internal network, triggering the release of hormones like auxin or modifying calcium flows. These hormones then initiate concrete reactions: accelerated growth, leaf orientation, or even cell reinforcement. In other words, when a plant "hears" a sound, it doesn't really listen, but it physically feels its effects inside its cells.
Several experiments show that plants do indeed respond to music. For example, in a well-known study conducted by Dorothy Retallack in the 1970s, plants exposed to classical music showed better growth than those exposed to rock music or complete silence. More recently, researchers have observed that plants exposed to certain sound frequencies, around 250 Hz to 500 Hz, tended to produce more biomass. It is also known today that certain sound vibrations stimulate the production of specific proteins related to growth in plants. Although not all mechanisms are fully understood, current experiments validate a real response of plants to various types of music and vibrations, with measurable effects on their growth and health.
Some studies suggest that musical vibrations could influence the opening of stomata, pores present on the surface of leaves, allowing plants to optimize their gas exchanges with the environment.
The science called 'plant bioacoustics' studies how sounds and vibrations affect the growth, health, and biological mechanisms of plants.
Some winemakers sometimes play classical music in their vineyards, believing that it not only enhances the growth of the vines but also improves the quality of the grapes harvested.
In India, research has concluded that certain specific musical frequencies (between 100 Hz and 500 Hz) can significantly improve the germination and yield of agricultural crops such as rice and soybeans.
Some laboratory studies and scientific experiments indeed show that plants respond to music, such as increased growth or better resistance to stress factors. However, the results remain variable and require further in-depth research to fully confirm these effects.
Studies suggest that classical music, particularly pieces rich in soft tones or harmonious rhythms, appears to promote plant growth more than loud or aggressive music.
The recommended exposure duration varies, but generally, exposing plants to soft music for 1 to 3 hours a day is sufficient to observe positive effects on their growth or long-term health.
No, plants do not have auditory organs or hearing abilities like humans. However, they can perceive sound vibrations through their cells, allowing them to respond to music in an indirect way.
No, different species of plants can exhibit different reactions to music. Some plants appear to be more sensitive to sound vibrations, while others show little or no noticeable change.
