The objective of this study was to develop a generalized, simple
transpiration model by: (a) collecting a comprehensive transpiration
data set using the CHP method in orchards of the main fruit
tree species, namely olive, citrus, peach, apple, pear, apricot, pistachio
and walnut and (b) calibrating the conductance model of
Orgaz et al. (2007) for the different species. This model is explicitly
oriented to the calculation of tree crop water requirements for
irrigation management,thus it was designed with functionality and
low input requirements as its main features.
