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.
Characteristics of a sound wave. Since sound is a wave, we can relate the properties of sound to the properties of a wave. The basic properties of sound are: pitch, loudness and tone. Pitch.
