Abstract

More and more attentions have been taken to the effects of environmental stresses on the growth and development of plant cells and tissues. Making efforts on this field would enhance plant adaptability to varied environments and implement extensively efficient agricultural technologies. Using callus cultured from stalks of Actinidia chinensis, this study dealt with the effects of sound stimulation on plant cell energy metabolism, i.e., content of ATP. The results indicated that there occurs bi-directional effect of ATP content on sound field stimulation. The sound intensity of about 100 dB and sound frequency of approximately 1000 Hz are optimal external stresses for energy metabolism of A. chinensis. The experimental data showed that moderate sound field would be advantageous to growth and development of woody plants. The mechanisms of ATP content effects of sound stimulation on A. chinensis callus were comprehensively discussed in the light of cytobiology and molecular biology. Whereas the essential mechanisms of biological effects of environmental stresses remain further research.
