Steps toward an improvement in process-based models of water use by fruit trees: A case study in olive

Diaz-Espejo, A.; Buckley, T.N.; Sperry, J.S.; Cuevas, M.V. - In: Agricultural Water Management 114 (2012) C, pp. 37-49

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....

Average daily light interception determines leaf water use efficiency among different canopy locations in grapevine

Medrano, Hipólito; Pou, Alicia; Tomás, Magdalena; … - In: Agricultural Water Management 114 (2012) C, pp. 4-10

In Mediterranean areas grapevine water use efficiency (WUE) is becoming an important issue as grapevine production and quality are largely dependent on irrigation, and given the large area of this crop in this region. Under semi-arid conditions, grapevine water consumption rises up to 700mm/year...
