- Intervention effect Cotyledon burning propagated variation potential into pumpkin true leaves.
- Intervention effect Cotyledon burning decreased photosynthetic CO2 assimilation in pumpkin true leaves.
- Intervention effect Cotyledon burning increased non-photochemical fluorescence quenching in pumpkin true leaves.
- Intervention effect Respiration was activated insignificantly after cotyledon burning.
- Association Photosynthetic response magnitude was linearly related to variation potential amplitude.
- Observation Variation potential generation accompanied apoplast alkalization of 0.4 pH unit.
- Observation Variation potential generation accompanied cytoplasm acidification of 0.3 pH unit.
- Intervention effect Acidifying the incubation medium stimulated non-photochemical quenching in isolated chloroplasts.
- Mechanism The authors concluded that intracellular and extracellular pH changes contribute to variation-potential-induced photosynthetic responses.
