Abstract

This study was carried out to examine the effects of different irrigation intervals applied to the Gemlik olive variety grown in Şanlıurfa, which has semi-arid climate conditions, on some characteristics of the leaf stomata. For this purpose, leaf samples taken at harvest time from 12-year-old Gemlik olive variety trees irrigated at different intervals (control, 7, 14, 21, 28, and 35 days) were used as plant material. Leaf samples were taken from the top, middle and basal parts of the shoots, and the changes in stomatal characteristics were also examined depending on the location of the leaves on the shoot. The analyses show that irrigation intervals were made significant differences in stoma density, stoma size, stoma area, stoma shape coefficient, relative stoma area, and potential conductivity index. Irrigation interval with the highest stomatal density was determined as 35 days (413.05 stoma mm-2), and the lowest irrigation interval was determined as 28 days (365.75 stoma mm-2). We show that the stomatal density generally increased with the increase of the irrigationinterval, whereas the stomatal length and stomatal area decreased. The stomatal characteristics were changed according to the position of the leaves on the shoot, but this was more clearly in stomatal sizes. It was determined that the leaves at the top of the shoot have smaller stomata than the leaves in the middle and lower parts. It was determined that there was a strong relationship between stoma width and stoma length.

Özet

Bu çalışma, yarı-kurak iklim koşullarına sahip Şanlıurfa ilinde yetiştirilen Gemlik zeytin çeşidine uygulanan farklı sulama aralıklarının, yapraklarda yer alan stomaların bazı özelliklerine etkilerini incelemek amacıyla yürütülmüştür. Bu amaçla; farklı aralıklarla (kontrol, 7, 14, 21, 28 ve 35 gün) sulanan 12 yaşındaki Gemlik zeytin çeşidi ağaçlarından hasat zamanı alınan yaprak örnekleri bitkisel materyal olarak kullanılmıştır. Yaprak örnekleri, sürgünlerin uç, orta ve bazal kısımlarından alınmış ve sürgün üzerinde yaprakların bulunduğu konuma bağlı olarak da stoma özelliklerinin değişimi incelenmiştir. Sulama aralıklarının; stoma yoğunluğu, stoma boyutları, stoma alanı, stoma şekil katsayısı, oransal stoma alanı ve potansiyel iletkenlik indeksinde farklılıklar oluşturduğu saptanmıştır. Stoma yoğunluğu en yüksek olan sulama aralığı 35 gün (413,05 adet mm-2), en düşük olan sulama aralığı ise 28 gün (365,75 adet mm-2) olarak saptanmıştır. Stoma yoğunluğunun genel olarak sulama aralığının artışına bağlı olarak arttığı, stoma boyu ve stoma alanının ise azaldığı saptanmıştır. Yaprakların sürgün üzerinde bulundukları konuma göre stoma özellikleri değişim göstermiş ancak bu durum stoma boyutlarında daha net görülmüştür. Sürgün ucundaki yaprakların, orta ve alt bölümdeki yapraklara göre daha küçük stomalara sahip olduğu belirlenmiştir. Çalışmada; stoma eni ile stoma boyu arasında kuvvetli bir ilişki olduğu belirlenmiştir.
