Abstract

The effect of different irrigation treatments on the quality and antioxidant compounds of the virgin olive oil obtained from Memecik variety was determined in this study, which was carried out in three consecutive years. For this purpose, six different irrigation treatments (25%, 50%, 75%, 100% and 125%) were applied to an olive orchard using the drip method. According to quality criteria, free acidity and peroxide value were not influenced by the amount of irrigation. Differences in fatty acids among oil samples were found statistically significant. Among the hydroxytyrosol, gallic acid, oleuropein, chlorogenic acid, caffeic acid, vanillic acid, p-coumaric acid, ferulic acid, luteolin and apigenin, hydroxytyrosol and vanillic acid were influenced by the amount of irrigation water applied to olive trees, and there was a significant relationship among the irrigation treatments. Generally, an increase in the amount of irrigation water given was accompanied by a reduction in bitterness indices and total chlorophyll contents. In terms of oil yield and chemical quality, 25% irrigation treatment could be recommended under experimental conditions.

Özet

Bu araştırma üç yıl üst üste gerçekleştirilmiş olup farklı sulama düzeylerinin Memecik zeytin çeşidinden elde edilen sızma zeytinyağının kalitesi ve antioksidan bileşikleri üzerine etkisi incelenmiştir. Bu amaçla zeytin bahçesine damla sulama yöntemi kullanılarak altı farklı sulama oranları (%25, %50, %75, %100 ve %125) uygulanmıştır. Kalite kriterlerinden serbest asitlik ve peroksit değerlerinin sulama miktarından etkilenmediği tespit edilmiştir. Yağ asitleri açısından uygulamalar arasındaki farklar istatistiksel olarak anlamlı bulunmuştur. Hidroksitirozol, gallik asit, oleuropein, klorojenik asit, kafeik asit, vanilik asit, p-kumerik asit, ferrulik asit, luteolin ve apigenin arasında, hidroksitirozol ve vanilik asit değerleri uygulanan sulama suyu miktarından etkilenmiş ve sulama uygulamaları arasında önemli bir ilişki tespit edilmiştir. Genel olarak verilen sulama suyu miktarındaki artışa, acılık indeksi ve toplam klorofil içeriğinde azalma eşlik etmiştir. Yağ verimi ve kimyasal kalitesi açısından deneme koşullarında %25 oranında sulama uygulaması önerilmektedir.
