A: Sound waves of 125-250Hz or 100-2000Hz can promote plants.
2. What is the waveform of plant-induced wave?
A: Music sounds have a regular effect on plants. I don't know what shape it is.
3. When is it most effective for vegetables to emit plant-induced waves in a day?
I don't know
4. How many decibels of plant-induced waves do vegetables receive?
I don't know
5: Which scientist? What time? Where is it? For what plants? What comparative experiments have you done on plant sound interference? Get the above data.
A: In terms of music processing, Creath of the University of Arizona in the United States takes dicotyledonous seeds as the research object. Under certain growth conditions, it was found that the germination rate of music treatment group (natural background music) was significantly different from that of control group. There was no significant difference between the strong noise treatment group and the control group. Jeong of Korea National Institute of Agricultural Biotechnology studied the effects of classical music and single-frequency vibration signals on plant genes under light and dark conditions. The results showed that the expression of aldolase (catalytic cracking reaction) gene increased significantly at the frequency of 125-250Hz.
In pure tone processing, Johnson of Rice University stimulated the budding seeds of Arabidopsis thaliana with sound waves of about 50Hz and 90dB, and found that the hypocotyl elongation and gene expression level of the seeds increased. The cooperative research of Institute of Mechanics of Chinese Academy of Sciences, Department of Applied Chemistry of China Agricultural University and Department of Engineering Mechanics of Tsinghua University shows that a certain range of sound wave stimulation can affect the synchronization of tobacco cell division, promote DNA synthesis in S phase of cell division, contribute to cell mitosis and promote plant growth and development. Studies by the Institute of Life Sciences of South China Normal University and the School of Bioengineering of Chongqing University have found that sound waves can obviously enhance or inhibit the ATP content in kiwifruit callus. Moderate sound wave stimulation improves the activity of adenosine triphosphate ATP synthase, which is beneficial to the energy metabolism level of plants. In 2009, Hou Tianzhen used QGWA-03 plant audio generator (frequency range 100-2000Hz) to carry out audio processing on tomatoes, and found that tomato yield increased by 13.2% and gray mold decreased by 9.0%.
6. Which website or website has objective data that scientifically introduces the effects of sound waves on plants?
China HowNet, looking for "plant sound waves", can get literature and objective data.
