Fruit load governs transpiration of olive trees.
We tested the hypothesis that whole-tree water consumption of olives (Olea europaea L.) is fruit load-dependent and investigated the driving physiological mechanisms. Fruit load was manipulated in mature olives grown in weighing-drainage lysimeters. Fruit was thinned or entirely removed from trees at three separate stages of growth: early, mid and late in the season. Tree-scale transpiration, c...
متن کاملVariability 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...
متن کاملThe Role of Olive Trees Distribution and Fruit Bearing in Olive Fruit Fly Infestation
The role of fruit bearing percentage in olive fruit fly infestation is investigated through a simulation model where the spatial law of dispersion distances were modeled via an appropriate exponential law. The dispersal of olive fruit flies was simulated for two distinct cases, an olive grove with no olive fruits and an olive grove with 100% olive fruit bearing. Results showed that when no oliv...
متن کاملMeasuring the Sap Flow of Eucalyptus Trees
We describe the design and implementation of Savia, a sensor network system for measuring the sap flow of eucalyptus trees. Unlike prior sensor network systems, which generally take a vertically integrated approach and build everything from scratch, Savia is built out of several existing sensor systems. The difficulties we encountered when combining these systems demonstrate why a vertically in...
