Other claims from this paper (7)
- Method / resource In all studies, sap velocity measured with heat-balance sensors overestimated maize transpiration.
- Observation The sap flow sensor errors were small in the evening and early morning.
- Observation The sap flow sensor errors became larger with increasing transpiration.
- Observation The sap flow sensor errors reached a maximum when solar irradiance was the largest.
- Method / resource A linear calibration equation, T’ = 0.65 V + 0.39, was established to convert measured sap flow velocity to corrected transpiration rate.
- Method / resource Using the calibration equation, the largest sap flow error was reduced by 50% in the pot experiment.
- Method / resource Using the calibration equation, the largest sap flow error was reduced by 50% in the field study.
