Fude Yao; Kenneth Corey HortScience 1994. doi:10.21273/hortsci.29.5.474a
Other claims from this paper (7)
- Observation Under isothermal nutrient solution, tomato sap pressure rose to a maximum within 10 to 75 minutes.
- Observation Maximum sap pressure varied from 20 to 150 kPa.
- Observation Sap pressure maxima decreased over time in all plants.
- Intervention effect Stopping root aeration lowered pressure after about 30 minutes.
- Intervention effect A nitrogen atmosphere lowered pressure after about 30 minutes.
- Intervention effect Aeration resupply partially reversed the pressure decrease.
- Intervention effect Increasing solution osmolarity caused near instantaneous sap pressure changes.
