摘要
采用金属电极测定了石蒜叶片的微弱电波信号 .石蒜植物叶片微弱低频电波信号的变化区间是 4～ 30 μV ,其低频信号随叶片基部向先端延伸而减弱 ,这种微弱信号随着植物叶片在空间的分布可构成叶片等电势线 .石蒜叶片微弱电波动信号具有从基部向上的生理向性 .
Weak electrical signal of leaves in Lycoris radiata has been studied with metal electrode,which the electric potential range of the low frequency signal is 4～30?μV,and the signal became weaker from bottom to tip of leaves.The weak signal formed the equipotential surfaces with extending of leaves in space.This kind of weak signal has the property of physiological direction from bottom to top of plant.
