Abstract:
Abstract Insight into the relationship between plant growth and physical stimulation is one of focuses of modern biomechanics. In this study, several primary plant physiological indexes related to root development in sound field were measured. It was expected to obtain some information about stress effect on roots development and growth of woody plant through the study. The results showed that sound wave stimulation of different intensities had some dual effects on root development of A. chinensis plantlets that came from its call. The sound wave stimulation of moderate intensity increased the root activity, total length and number of roots, whereas decreased the permeability of cell membrane. The optimal stimulation of sound intensity to root development of A. chinensis plantlet was 100 dB or so. As the intensity of sound stimulation exceeded certain limit value (110 dB), the increase of root activity would be restrained chiefly owing to the integrality of cell membrane being destroyed. The mechanisms of sound stimulation stress on plant root development were also discussed on the level of cellular and molecular biology. Fig 2, Tab 1, Ref 13
