摘    要:对测得的瓜叶菊(Senecio cruentus)、雏菊(Bellis perennis)和茼蒿(Chrysanthemum coronarium)三种盆栽菊科植物的电信号进行了短时傅立叶变换分析.三种菊科植物的电信号幅值的变化范围分别为-34.07~35.15μV、-94.37~25.03μV和-22.92~21.71μV,能量谱分别主要分布在约0.15 Hz、0.08 Hz和0.11 Hz以下.据此表明三种菊科植物的电信号均为微弱低频信号.另外,还发现三种菊科植物的电信号中于不同时刻出现频率范围不同的“动作电波”成分.

关 键 词:菊科植物  植物电信号  短时傅立叶变换  动作电波

Abstract:The electrical signal of three species in compositae,namely,Senecio cruentus、Bellis perennis and Chrysanthemum coronarium grown in flowerpots,was determined and then analyzed by the method of short time Fourier transform.The variation range of the amplitude of the electrical signals in the three species is(-34.07)~35.15 μV,-94.37~25.03 μV and-22.92~21.71 μV respectively.The energy spectral density mostly distributes below about 0.15 Hz,0.08 Hz and 0.11 Hz respectively.Thus,the electrical signal in the three species is a weak and low-frequency signal.The action electrical wave which has different frequency range emerges in the electrical signals in different time.
Keywords:compositae  plant electrical signal  short time Fourier transform  action electrical wave
