Abstract:
The heat dissipation technique was applied to measure the sap flow velocity of Pinus elliottii in the artificial forest of subtropical southern China from May 21st 15:54 to June 6th 9:04 in 2003. The results showed that the average sap velocity of the measured three trees was 82.43 cm·d -1 with a normal pattern of diurnal variation,during the measuring period. Air temperature,soil temperature,solar radiation and relative humidity of atmosphere,were the most significant factors effecting the sap flow velocity. We also found that the data quality control of sap flow velocity could be performed by the ratio of maximum value to average value for sap flow observations and its concerned confidence interval analysis,correlation analysis and paired t-test.
Key words: Pinus elliottii, sap flow, thermal dissipation probe (TDP)
