Other claims from this paper (8)
- Observation Sap pressure reached a maximum in 10 to 75 minutes in nutrient solution.
- Observation Maximum sap pressure ranged from 20 to 150 kPa.
- Intervention effect Repeated pressure cycles reduced sap pressure maxima.
- Intervention effect Nitrogen atmosphere decreased sap pressure after about 30 minutes.
- Intervention effect Resupplying aeration partially reversed the pressure decrease.
- Intervention effect Imposing a root zone temperature gradient changed sap pressure nearly instantly.
- Intervention effect Increasing solution osmotic potential changed sap pressure nearly instantly.
- Method / resource The sap pressure monitoring technique may help assess effects of root environments and plant health.
