| 摘 要： | 用铂丝电极分别测定了油松 (Pinustabulaeformis)和白皮松 (Pinusbungeana)的韧皮部、形成层和木质部的电波信号 .该信号波由具有一定的周期性的组峰或单峰波组成 ,不同松树种及同一种的不同部位的波特征既有相似性又有一定的区别 .主要以波峰的周期值为指标分析了不同种及同种不同部位波信号在白天 12h中的变化规律 ,并探讨了信号波与植物生理特性间的关系 .

| Abstract: | The weak electrical wave signals in phloem, cambium and xylem in P tabulaeformis and P bungeana have been tested by using metal electrode of platinum.The signal consist of serials wave and/or single wave, which have a periodicity.The signal would be different when the position of electrode or the special of plant is different.The value of period of wave is analyzed in different special,different position in 12 hours of a dayly time.The relationship between the regularity of wave and physiology has been discussed. |
