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 کاملWater Status of Olive Trees
Leaf water potential (') and leaf conductance (gl) were measured in the field in 20-year-old olive trees subjected to two treatments of soil water content (dry-farming and drip-irrigation). Differences between treatments of up to 0.35 MPa were observed in predawn , values. At midday, these differences were of up to 0.83 MPa. However, no significant differences between treatments were observed i...
متن کاملThe dynamic role of root-water uptake in coupling potential to actual transpiration
The relationship between actual (Eact) and potential (Ep) transpiration above a grass-covered forest clearing was investigated numerically and experimentally from simultaneous measurements of soil moisture content pro®les, mean meteorological conditions, turbulent heat and water vapor ̄uxes in the atmospheric surface layer, and soil hydraulic properties for two drying periods. The relationship ...
متن کاملInfluence of the Soil Water Content and Distribution on Both the Hydraulic and Transpiration Performance of ‘Manzanilla’ Olive Trees
This work was made with mature ‘Manzanilla’ olive trees in an orchard of a semi-arid area in southern Spain. Three water treatments were considered: Rainfed, in which the trees had rainfall as the only source of water supply; FAO, in which the trees were under localized irrigation to replace the crop water demand, with some roots left in drying soil; Pond, in which the whole rootzones of the tr...
متن کاملTranspiration and root development of urban trees in structural soil stormwater reservoirs.
Stormwater management that relies on ecosystem processes, such as tree canopy interception and rhizosphere biology, can be difficult to achieve in built environments because urban land is costly and urban soil inhospitable to vegetation. Yet such systems offer a potentially valuable tool for achieving both sustainable urban forests and stormwater management. We evaluated tree water uptake and r...
