Abstract

The electrical potential difference across the sieve plates in the primary phloem of Vitis vinifera was measured by inserting micro-electrodes into the sieve-tubes. The values obtained ranged from 4—48 mV. The potential across the transverse walls of the phloem fibres was also determined and found to range from 1—11 mV. These results are discussed in relation to the theory of translocation based on electro-osmosis put forward independently by Fensom and Spanner.
