Abstract: The non injurious local stimulation,such as a cold shock and the injurious stimulation,such as local burn,pricking the stem,chemicals and sever cut were applied to evoke the electrical wave transmission in the black pine ( Pinus thunbergii ) seedlings.The results have shown that the non-injurious stimulation could arouse the action potential (AP) transmission and the injurious stimulation could induce both VP and more complex AP (variation potential) transmission in the seedlings.The causes of the phenomena was discussed.
