The recently developed plant sensor of relative changes in leaf turgor pressure (LPCP probe) was compared with the turgor pressure output simulated with a process-based stomatal model (BMF model). Our results confirm the good agreement between the simulated turgor pressures and those derived from LPCP readings. The combined use of the BMF model...

Español: En la presente Tesis se han utilizado una amplia gama de técnicas experimentales y análisis de modelización para estudiar los mecanismos fisiológicos involucrados en el control de la transpiración y aplicar los conocimientos adquiridos en la optimización del riego de cultivos de árboles frutales. Dos enfoques principales fueron...

El experimento se está llevando a cabo durante la estación de crecimiento de 2010 en un olivar en seto de alta densidad con tres tratamientos de riego (Control con 100% de ETc Y dos tratamientos de riego deficitario controlado, ROC, con 20% y 60% de ETc). El objetivo es determinar la utilidad de la información obtenida con distintos índices,...

Background & Aims There is not a consensus on the best irrigation approach for super-high density (SHD) olive orchards. Our aim was to design and test a regulated deficit irrigation (RDI) strategy for a sustainable balance between water saving, tree vigour and oil production. Methods We tested our RDI strategy for 3 years in an 'Arbequina'...

Over the last years modeling plant transpiration has been pointed out as a powerful tool to optimize the management of irrigation in fruit trees. In this study we tested the hydromechanical model of stomata functioning proposed by Buckley et al. (2003), a model with a strong physiological basis. The great contribution of this model is that its...

We applied two process-based models in a hedgerow olive orchard with the aim of understanding the limitations and mechanisms behind the control of transpiration in olive trees under drip irrigation. One model is based on the biophysics of water flow through the porous media of soil and xylem. The other is a hydromechanical model based on the...
