Abstract：
:Using glass microelectrodes we studied (in spinach, a long-day plant) the characteristics of the intracellular potential of mesophyll cells as well as its response towards light, in particular during the transfer of the plant to an inductive photoperiod (transfer from short day to continuous photoperiod). When 20 minutes treatments of alternating white light (2 minutes) and darkness (2 minutes) are provided every 2 hours (during the photo-or nyctoperiod), the amplitude of the bioelectrical response increases after the transfer and follows a circadian pattern (Figs. 1 and 2). This phenomenon (amplification effect), specific to the transfer of vegetative plants, is probably linked to changes in energy metabolism or to structural modifications, e.g. properties of membranes. Bonzon et al. (1981) found a similar behavior of energetic charge and redox potential of the leaf after the transfer. The diversity of bioelectrical responses (amplification effect) obtained with different cells of the leaf suggests a metabolic specificity among apparently identical cells of the same tissue.
