- Observation Electrical stimulation of the stem frequently evoked action potentials.
- Observation Electrical stimulation of the stem never evoked variation potentials.
- Observation Heat wounding a leaf virtually always elicited a variation potential.
- Observation Heat-wound variation potentials were often accompanied by spikes.
- Observation Variation potential parameters decreased significantly with distance.
- Observation Heat stimulus rapidly altered stem elongation or contraction before electrical potential changed.
- Observation Light-off evoked negative-going extracellular potential changes.
- Observation Light-on evoked positive-going extracellular potential changes.
- Observation Light-off-induced membrane depolarization triggered action potentials.
- Observation Heat-wound-induced membrane depolarization triggered action potentials.
- Observation The authors interpret action potentials as electrical signals involving voltage-gated channels or pumps.
- Observation The authors interpret variation potentials as local consequences of a transmitted xylem hydraulic signal.
