Özet
The aim of the study was to identify the changes in olive and corresponding olive oil characteristics in responseto irrigation. Five olive cultivars (Halhalı, Sarı ulak, Nizip Yağlık, Kilis Yağlık and Karamani) from Turkish originwere harvested from their own traditional growing region (Mardin, Mersin, Gaziantep, Kilis and Hatayrespectively) from both irrigated and non-irrigated trees (rain-fed) for two consecutive crop years. Olives wereprocessed to oil with a laboratory scale system. Olive fruits were analyzed for their physico-chemical propertiesand phenolic composition and olive oils were analysed for fatty acid, triacylglycerol and sterol composition.Results have shown that average weight, flesh/pit ratio of olives were lower and dry matter and oil content werehigher in rain-fed trees than irrigated ones. Phenolic content and composition of fruits were cultivar dependentand responded differently to water supplement. Fatty acid composition of olive oils mainly remained unchanged,however the concentration of individual triacylglycerols behaved in distinct ways. Total sterol and ?-sitosterolcontents increased and decreased for various cultivars whereas ?-5-avenasterol increased in all cases. Sarı ulakvariety was well separated from other varieties by principal component and hierarchical cluster analysis both inrain-fed and irrigated treatments.
