Other claims from this paper (9)
- Intervention effect Increasing calcium generally decreased initial rubidium uptake.
- Observation The inhibitory effect of high calcium on rubidium uptake diminished after longer incubation.
- Intervention effect When ice encased at −1 °C in water, wheat cell viability declined rapidly.
- Intervention effect Ice encasement markedly reduced rubidium uptake before significant viability decline or increased ion efflux.
- Intervention effect Cell damage increased as icing temperature fell from −1 to −2 and −3 °C.
- Intervention effect Calcium in the suspension medium reduced icing injury.
- Intervention effect Slow cooling reduced cell viability more than rapid cooling at −10 to −30 °C.
- Intervention effect Slow cooling reduced ion uptake more than rapid cooling at −10 to −30 °C.
- Mechanism The authors infer that prolonged ice encasement first affects ion transport whereas brief lower-temperature cooling causes broader membrane damage.
