Other claims from this paper (10)
- Intervention effect Ethylene caused a rapid decrease in flower water uptake about four hours after treatment began.
- Observation Flower wilting followed decreased water uptake about two hours later.
- Intervention effect Carbon dioxide inhibited the decline in water uptake.
- Intervention effect Carbon dioxide inhibited wilting.
- Intervention effect Ethylene did not affect stomatal closure.
- Intervention effect Ethylene enhanced ionic leakage, measured by vacuolar chloride efflux.
- Intervention effect Propylene gassing initiated autocatalytic ethylene production within 2.4 hours.
- Observation The increase in ethylene production preceded ionic leakage and declining water uptake by several hours.
- Mechanism The authors inferred that ionic leakage does not cause the initial rise in ethylene production.
- Mechanism The authors inferred that ionic leakage may explain the autocatalytic phase of ethylene production.
