Analysis of plant response to frequency spectrum of audio signals

摘要

In our previous study, a measuring system was successfully used to detect and analyze plant response to audio signals. In this experiment we examined some specificities in plant response to a specific frequency band. The measuring system was designedwith a multi-channel input for the simultaneous acquisition and output for the analysis of response signals from several plants. And we made a signal generator for single frequency with software. Plants replied more promptly and largely to higher frequency signals, and more sensitively to particular frequency bands. These results show that there is response specificity in plant to the frequency of imposed audio signals. If frequency signals with more sensitive response have an effect on growth of plantpositively, it may be possible to compose a specific music which is more effective in stimulating the growth of a specific crop.
