Effects of Synchronized Sound Waves in the Form of Indian Classical Instrumental Music (Strings and Closed Pipes) on Fruit Ripening of Psidium guajava L. and Manilkara zapota (L.) P. Royen

Harmonic frequencies of octaves in Indian Classical music influence the growth of the plants; starting from germination to the fruit ripening. It has been observed that sound waves at different frequencies, sound pressure levels, exposure periods and distances of the experimental materials from the sound source influence the plant growth. In the present research work, experiments were conducted to study the effect of Indian classical Ragas (Instrumental) having different harmonic frequencies of octaves on fruit bearing plants and fruit ripening in Psidium guajava (guava) and Manilkara zapota (sapodilla). The observations showed the plants exposed to the ?dose-dependent? and ?time-dependent? soothing, harmonic frequencies of octaves of Indian Instrumental Classical music showed an earlier fruiting and earlier fruit ripening. Moreover, other biochemical analysis of some primary metabolites in the ripened fruits treated with harmonic, melodious Classical Music showed astounding results of an increased concentration of metabolites like reducing sugar which was found to be 8.12mg/ml in Psidium guajava and 8.74mg/ml in Manilkara zapota, carbohydrates which was found to be 0.38 mg/ml in Psidium guajava and 0.81 mg/ml in Manilkara zapota and proteins which was found to be 8.12mg/ml in Psidium guajava and 8.74mg/ml in Manilkara zapota inferring certain development of fruit qualities.
