Abstract
A polyacrylate chamber with three pools was developed to measure the c hanges in electrical membrane resistance during generation of receptor potentials upon mechanical stimulation in Chara internodal cells. The membrane resistance decreased at the peak of the receptor potentials. The present results support the hypothesis that the receptor potentia l is generated by activation of ion channel(s). This is the first succ ess in demonstrating a change in the membrane resistance in receptor p otential induced mechanically in plants.
