Recent research has shown that plants are not mere spectators of the sound around them. A study published in the journal Plant Signaling & Behavior found that exposure to classical music, especially compositions by Mozart and Beethoven, caused a significant increase in growth rate and biomass production in tomato and strawberry plants.
Scientists discovered that sound vibrations, particularly in the frequency range between 125 and 250 Hz, stimulate the opening of stomata (leaf pores) and promote the activity of key enzymes in photosynthesis. This translates into better gas exchange and more efficient capture of sunlight.
- Plants exposed to classical music: grew 20% faster and produced 15% more fruit than the control group.
- Plants exposed to white noise or heavy rock: showed stalled growth and even signs of water stress.
This phenomenon, known as plant bioacoustics, suggests that plants possess sound perception mechanisms that are not yet fully understood, which could revolutionize urban agriculture and precision greenhouses.
