Abstract :
The characteristics of noise background and randomness of plant electric signal are introduced. The measurement of transmission speed of electric signals of plant based on correlation method after pretreatment of the signal with denoising method of lifting wavelet transform were analyzed. Experiments prove that the analysis of plant signals will be more efficient if the lifting wavelet transform is adopted and that when the transmission speed of the signal is relatively fast, the correlation method is a comparatively practical measuring method. On the basis of this, transmission speeds of variation signals under three kinds of stimulus were successfully obtained using plant aloe.
