Resumen: The scarcity of water for agricultural use is producing a generalization of deficit irrigations in most of the fruit trees. Regulated deficit irrigation in olive trees is scheduled with a period of water stress during the pit hardening phase with low or, even, no decrease in yield. During this phenological stage, fruit is a great sink of assimilates and competes with vegetative growth, producing a significant change in the water relation of the tree. The aim of this work is to study the water relations in leaves and fruits in a period of drought during the phenological stage of pit hardening in a mature (43-year-old) table olive orchard. Water relations of leaves and fruits were compared between a Control of fully irrigated trees and Stressed trees (with a period of drought from 1 week after the beginning of pit hardening until 1 week before harvest). The water stress conditions were considered as low level, according with the stem water potential data. Leaf water relations were quick...
