本文介绍了一种改进的测定燕麦胚芽鞘上电位差的方法。观察到电波以高达14 mm/hr的速度沿胚芽鞘向下传播。在完整胚芽鞘的翅照射后或在切割的顶部施用3·吲哚乙酸后观察到电波。这种波动似乎与生长素的转移密切相关。生长素的转运机制被认为与波有关。这表明，电波可能是有用的生长素的生物测定。
An improved technique for measuring electric potential differences on the etiolated Avena .coleoptile is described. An electric wave has been observed to travel down the coleoptile at a speed of up to 14 mm/hr. The wave is observed either follo-wing illumination of the intact coleoptile or following application of 3·indolylacetic acid to the cut top. The wave appears to be associated-intimately with the stream of auxin being translocated. The mechanism of auxin translocation is considered in relation to the wave. It is suggested that the electric wave may be useful as a bioassay for auxin.
