Effect of Music on Plants – An Overview, Goenka University (Jan 2016)
In this paper, the influence of acoustic frequencies including those of music on the growth pattern of plants as observed by many researchers have been reported. Besides, the authors have carried out a pilot study to observe the response of Tagetes sp. (marigold) to Light Indian Music and Meditation Music as well as to noise. They have also monitored the germination of Cicer arietinum (chickpea) on exposure to Light Indian Music. It could be commented that music promoted the growth and development of the plants, including germination whereas noise hindered it. Possibly, specific audible frequencies and also musical frequencies facilitate better physiological processes like absorption of nutrients, photosynthesis, protein synthesis, etc. for the plant and this is observable in terms of increased height, higher number of leaves and overall more developed and healthier plants.
Effects of Radio Frequency Water Treatment on Revival of Wilted Flowers, ATASA Research (Feb 2015)
An experiment to detect an effect of radio frequency (RF) radiation (27.5 MHz) on properties of water through its effects on the revival of wilted catsear dandelions was performed.
The positive results indicate that the RF treatment significantly affects water transport within the plant. It is inferred that it enhances osmosis into cells and capillary transport through the plant’s vascular system. The effects began to show after about 20 minutes, and efficacy of the water treatment lasted for a period of at least several hours.

Update on the Effects of Sound Wave on Plants, Yeungnam University, Korea (Mar 2014)
Sound waves with specific frequencies and intensities can have positive effects on various plant biological indices including seed germination, root elongation, plant height, callus growth, cell cycling, signaling transduction systems, enzymatic and hormonal activities, and gene expression.
Sonication and ultrasound: impact on plant growth and development, University of Debrecen, Hungary (May 2014)
Plant biotechnology, and plant tissue culture in particular, could benefit from new means to stimulate plant growth and development. Although the number of studies is still limited, there is evidence that sonication using low frequencies of sound (as little as a few dozen Hz) to as high as ultrasound (several dozen kHz) may increase organogenesis.
Based on experimental evidence accumulated to date, it is clear that sound and sonication can strongly influence growth and morphogenesis in plants.
Advances in Effects of Sound Waves on Plants, China Agricultural University (Feb 2014)
Abstract: Sound waves technology has been applied to different plants. It has been found that sound waves were at different frequencies, sound pressure levels (SPLs), exposure periods, and distances from the source of sound influence plant growth. Experiments have been conducted in the open field and under greenhouse growing conditions with different levels of audible sound frequencies and sound pressure levels. Sound waves at 1 kHz and 100 dB for 1 h within a distance of 0.20 m could significantly promote the division and cell wall fluidity of callus cells and also significantly enhance the activity of protective enzymes and endogenous hormones. Sound waves stimulation could increase the plant plasma-membrane H+-ATPase activity, the contents of soluble sugar, soluble protein, and amylase activity of callus. Moreover, sound waves could increase the content of RNA and the level of transcription. Stress-induced genes could switch on under sound stimulation. Sound waves at 0.1–1 kHz and SPL of (70±5) dB for 3 h from plant acoustic frequency technology (PAFT) generator within a distance ranged from 30 to 60 m every other day significantly increased the yield of sweet pepper, cucumber and tomato by 30.05, 37.1 and 13.2%, respectively. Furthermore, the yield of lettuce, spinach, cotton, rice, and wheat were increased by 19.6, 22.7, 11.4, 5.7, and 17.0%, respectively. Sound waves may also strengthen plant immune systems. It has been proved that spider mite, aphids, gray mold, late blight and virus disease of tomatoes in the greenhouses decreased by 6.0, 8.0, 9.0, 11.0, and 8.0%, respectively, and the sheath blight of rice was reduced by 50%.

Conclusion: The music acoustic frequency could stimulate the IAA secretion in plants.
The Effects of Different Musical Elements on Root Growth and Mitosis in Onion (Allium cepa) Root Apical Meristem (Musical and Biological Experimental Study), Trakya University, Turkey (Feb 2007)
In this study effects of strong, complex, rhythmic accent classical music with sekunda and kvarta intervals... were investigated in onion (Allium cepa) root tip cells during germination. Both kinds of music have positive effects on root growth and mitotic divisions in onion root tip cells but rhythmic dynamically changing lyrics affected much better.
In conclusion, plants grow faster in exposure to positive music. The knowledge can be applied in agriculture to increase the yield.
Measuring effects of music, noise, and healing energy using a seed germination bioassay, University of Arizona (Feb 2004)
Methods: A series of five experiments were performed utilizing okra and zucchini seeds germinated in acoustically shielded, thermally insulated, dark, humid growth chambers. Conditions compared were an untreated control, musical sound, pink noise, and healing energy. Healing energy was administered for 15-20 minutes every 12 hours with the intention that the treated seeds would germinate faster than the untreated seeds.
Results: Musical sound had a highly statistically significant effect on the number of seeds sprouted compared to the untreated control over all five experiments for the main condition (p < 0.002) and over time (p < 0.000002). This effect was independent of temperature, seed type, position in room, specific petri dish, and person doing the scoring. Musical sound had a significant effect compared to noise and an untreated control as a function of time (p < 0.03) while there was no significant difference between seeds exposed to noise and an untreated control. Healing energy also had a significant effect compared to an untreated control (main condition, p < 0.0006) and over time (p < 0.0001) with a magnitude of effect comparable to that of musical sound.
Conclusion: This study suggests that sound vibrations (music and noise) as well as biofields (bioelectromagnetic and healing intention) both directly affect living biologic systems, and that a seed germination bioassay has the sensitivity to enable detection of effects caused by various applied energetic conditions.
