Plants in good vibes 🔊🌱 Role of sound waves in improving plant growth & protecting against pests.
💡 The response of plants to sound has not been extensively elucidated, primarily due to the lack of recognized organs in plants designed for the perceptions of air vibrations.
📚 An arising scientific interest has been focused on the response of plants to sound waves, indicating that plants can generate (via the generation of tension in the xylem) and react to sound signals from their environment.
🤔 Many studies involving the use of sound as a trigger lacked proper standardization, being recognized as fringe science.
🎵 However, recent scientific findings using cutting-edge technology, quality control for hertz and decibel levels, and the integration of big data have succeeded in delivering quality data.
📌 Overview of scientific findings:
-> induction of certain photosynthetic enzymes activity (including Rubisco small sub-unit gene) in rice following 125 and 250 Hz sound treatment,
-> enhancement of plant growth by promoting CO2 fixation,
-> induced production of the growth-related hormones auxins (IAA) and gibberellin (GA) 3 and stress-related hormones salicylic acid (SA) and jasmonic acid (JA)
-> changes in target gene expression, including redox homeostasis, phytochemical biosynthesis, and defense response increased in exposure to 500 Hz sound waves.
🎯 It can be concluded that sound wave treatment can be considered a new type of trigger that can effectively elicit protection mechanisms when exposed to environmental stresses.
