Resumen: © 2014 Elsevier B.V. Pit hardening period is the phenological stage when water stress is recommended in regulated deficit irrigation (RDI) in olive trees. In table olive trees, fruit growth is a very important process which could affect the final profit of the yield. RDI scheduling based on water status measurements could improve water management, but accurate threshold values are needed. Previous works in low fruit load conditions suggested -1.8MPa of midday stem water potential as >first step> of water stress level where no variations of fruit growth have been detected. The aim of this work is to describe the physiological response of table olive trees with a significant yield in a moderate water stress conditions during pit hardening period. Water relations of Control (no water stress) trees and Stressed trees were studied in a mature table olive orchard in Seville (Spain). Control trees were irrigated with 100% of ETc and values around field capacity were measured. Irrigation in S...
