Studies on the plant electric wave signal by the wavelet analysis

摘要：

In this study, we choose that the db3 wavelet as the basis function to decompose the electric wave signal in 5 levels and a low and high frequency coefficient of 6 species plants are obtained, and coefficients after denoise are reconstructed for the first time. A result of the analysis of the wavelet in plant electric wave signals indicates that plant electric wave signals are of changing of characters in the each frequencies scale, In the low frequency level, the main character of the plant electric wave signal is reflected; in the high frequency level, the noise of the determined signal and also the mutation of the signal are reflected respectively. That the denoised signal of plants by wavelet analysis is similar with the original one indicates that the wavelet analysis is fit for studies on the plant electric wave signal. There are-200～500μV of the electric wave signals in growing plants.
