Variability with xylem depth in sap flow in trunks and branches of mature olive trees.
Knowledge of sap flow variability in tree trunks is important for up-scaling transpiration from the measuring point to the whole-tree and stand levels. Natural variability in sap flow, both radial and circumferential, was studied in the trunks and branches of mature olive trees (Olea europea L., cv Coratina) by the heat field deformation method using multi-point sensors. Sapwood depth ranged fr...
متن کاملSpatial sap flow and xylem anatomical characteristics in olive trees under different irrigation regimes.
The compensation heat pulse (CHP) method is widely used to estimate sap flow and transpiration in conducting organs of woody plants. Previous studies have reported a natural azimuthal variability in sap flow, which could have practical implications in locating the CHP probes and integrating their output. Sap flow of several olive trees (Olea europaea L. cv. 'Arbequina') previously grown under d...

15 صفحه اولEnvironmental regulation of xylem sap flow and total conductance of Larix gmelinii trees in eastern Siberia.
Xylem sap flow and environmental variables were measured on seven consecutive midsummer days in a 130-year-old Larix gmelinii (Rupr.) Rupr. forest located 160 km south of Yakutsk in eastern Siberia, Russia (61 degrees N, 128 degrees E, 300 m asl). The site received 20 mm of rainfall during the 4 days before measurements, and soil samples indicated that the trees were well watered. The tree cano...
متن کاملBranch sap flow in a mature olive tree: Dynamics and relation to architectural traits
This study examined how sap flow in shoots and branches of a mature olive tree (Olea europaea ‘Coratina’) related to morphological traits which are linked to tree hydraulic architecture. Spatial and temporal variations of sap flow within the tree canopy were investigated; they were analyzed with respect to the ratio between sapwood area and leaf area (SA/LA), and in relation to evaporation dema...
