Sap flow in a mature olive tree: dynamics and quantification in trunk and branches
Original language description
The analysis of water flow from vegetation in ecosystems - natural and cultivated - is a relevant subject in the study and prevision of water budget in systems prone to actual or economic water scarcity. The research focuses on transpiration (sap flow) of olive trees, an ecosystem common in areas of Mediterranean region with semi-arid climate. The work has been carried out on distinct sets of sap flow data, collected on an olive tree using different thermal methods (Heat Field Deformation - HFD and StemHeat balance - SHB) and performing measurements at individual measuring points (shoots, branches, trunk sectors). The data sets of measurements performed by the HFD and by the SHB have been integrated in order to study the dynamics of xylem flux and thedifferent flow regimes in shoots, branches and trunk. In particular, we have focused on the dynamic response of sap flow to meteorological conditions and to soil water status; some dynamic parameters have been studied (rate of change of
