Other claims from this paper (11)
- Association Burn-induced variation-potential propagation velocity declined with distance from injury.
- Association Heating-induced variation-potential propagation velocity remained constant with distance.
- Association Burn- and heating-induced variation-potential amplitudes did not depend on distance.
- Association Mechanical-injury variation-potential amplitude declined with distance.
- Observation Simulation indicated turbulent diffusion from damage as a possible wound-substance propagation route.
- Observation Simulation indicated secondary active production in intact cells as another possible wound-substance propagation route.
- Intervention effect Heating- and burn-induced potentials entering intact pea leaves raised NPQ.
- Observation The photosynthetic response was absent after mechanical injury.
- Association Burn-induced NPQ increase was biphasic versus single-phase after heating.
- Intervention effect NPQ amplitude was slightly higher under burn than heating.
- Mechanism Authors suggest stimulus-specific potential parameters may determine photosynthetic response differences.
