Fruit load governs transpiration of olive trees

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...

The 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...

Fruit Transpiration: Mechanisms and Significance for Fruit Nutrition and Growth

Transpiration and Photosynthesis of the Olive Tree: a Model Approach

Preliminary results of simulation by the RATP (Radiation Absorption, Transpiration and Photosynthesis) model on olive tree are presented. At leaf level, Jarvis ́ stomatal conductance (gs) model and Faquhar ́s photosynthesis (A) model were parameterised on 2-year-old plants under controlled conditions. At canopy level the spatial distribution of leaf area density of a 31-year-old tree was describe...

Influence of Irrigation Scheduling on Fruit Quality of Young Potted ‘Manzanilla de Sevilla’ Olive Trees

The aim of this work was to analyse the influence of soil water content and distribution on fruit quality in 5-year-old ‘Manzanilla de Sevilla’ olive trees in pots subjected to different irrigation treatments for 3 years (2007-2009). The experiment was carried out near Seville, in southwest Spain. Four water treatments were considered: 1) T0, trees were under dry farming conditions except for s...
