Abstract

Abstract:

Objective: The azimuthal difference of sap flux density is one of the important factors affecting the accuracy of individual transpiration estimation. Because of asymmetry of sap flow in different azimuths,how to simplify the treatment to better estimate the average sap flow rate of a plant will be very important Method: In this study,the thermal dissipation technique (TDP) was used to continuously and synchronously monitor the sap flux density of the four vertical orientations of the trunk of Pinus sylvestris var. mongolica during the whole growing season in Horqin sandy land,and the precipitation and soil moisture content were also synchronously measured. Result: The relative sap flux density (the sap flux density divided by the maximum value during this azimuth observation,J_s/max) of P. sylvestris var. mongolica had significant azimuthal variation (P < 0.01),among which relative sap flux density in south-side (J_s/max-S) is the highest. The values of J_s/max from four azimuthal directions in a tree showed significant inter-individual differences,and there was no distinct relationship between them. Soil water deficit was able to cause a synchronous and significant decrease in sap flux density of all directions (P < 0.05). By comparing the representativeness of the mean sap flux density (the mean value of four vertical directions) of the whole tree in different directions,a simplified model for estimating the mean sap flux density of the whole tree was established with the sap flux density on the north side of the trunk (J_s/max-N) (slope=1.015,Adj.R²=0.99,P < 0.01). The model has an accuracy of 0.99 by independent sample testing. Conclusion: There are significant differences in the sap flux density in different azimuths of P. sylvestris var. mongolica trunk,and the differences also varied in individuals. There is a high correlation among J_s/max in different directions. For P. sylvestris var. mongolica grown in sandy land,the average sap flux density of the whole tree can be accurately estimated with the sap flux density measured from the north-side of the trunk.
