Abstract Chilling auxin‐depleted, etiolated stems of Pisum sativum L. to 4°C for 60 s enhanced the production of previously described voltage transients 20‐fold. It is postulated that plasmalemmal permeability to Ca 2+ is increased at low temperature, permitting influx of the ion from the apoplast to the cytosol and thereby promoting production of transients. Heating to 40°C or 45°C elicits no increase in transients, and heating to 50°C leads to loss of turgor.
