Bazı Zeytin Çeşidi Yapraklarındaki Flavanol Miktarına Ağaç Yaşı, Çeşit ve Sulamanın Etkisi

Flavonoitler kimyasal yapıları ve biyolojik fonksiyonlarından dolayı bitki fizyolojisi ve sağlık açısından önemli bir gruptur. Bitkilerde bu bileşiklerin miktarı ve kompozisyonu yetiştirme tekniğine, çeşide, yetiştirildiği ekolojiye, sulamaya ve ürünün işleme şekillerine göre değişiklik göstermektedir. Zeytin bitkisinde bu maddelerin birçoğu sentezlenmektedir. Bu çalışmada, sulanan ve sulanmayan koşullarda iki farklı zeytin çeşidinin (Kilis Yağlık ve Gemlik) ve farklı yaşlardaki Kilis Yağlık çeşidi yapraklarının flavanol içerikleri yıl boyunca incelenerek çeşit, sulama ve yaş faktörlerinin etkileri belirlenmeye çalışılmıştır. Araştırma sonuçlarına göre Kilis Yağlık zeytin çeşidi yaprakları Gemlik zeytin çeşidi yapraklarına göre daha fazla flavanol içermektedir. Yaş faktörünün yapraklarda flavanol içeriğine önemli bir etkisi bulunmamıştır. Sulamanın etkisi yönünden değerlendirildiğinde ise sulanmayan koşullarda yapraklarda daha fazla flavanol sentezlenmiştir.

Effects of Tree Age, Cultivar and Irrigation on Flavanol Content of Some Olive Cultivar Leaves

Flavonoids are the important groups in terms of plant physiology and health due to their chemical structure and biological functions. The amount and composition of these compounds in plants vary according to growth techniques, cultivar, plant growing ecology, irrigation and crop processes. In this study, flavanol contents of leaves were examined throughout the year in two different olive cultivars (Kilis Yağlık and Gemlik) and Kilis Yağlık variety at different ages to determine the effects of variety, irrigation and age factors on irrigated and irrigated conditions. According to research results, flavanol content of Kilis Yağlık cultivar leaves were contain more flavanols in terms of compared to Gemlik cultivar. There was no important effect of the age factor on flavanol content in leaves. Considering the effect of irrigation, flavanols were more synthesized in leaves on non-irrigated conditions.
