Hachiya Trabzon hurması (Diospyros kaki L. cv. Hachiya) çeşidinde değişik bilezik alma uygulamalarının meyve verimi ve pomolojik özellikler üzerine etkileri

Amaç: Bu çalışma, Trabzon hurması ağaçlarında bilezik alma uygulamalarının verim ve bazı pomolojik özelliklerine etkilerini belirlemek amacı ile 2019 yılında yürütülmüştür. Materyal ve Yöntem: Çanakkale ilinde yetiştiriciliği yaygın olarak yapılan ‘Hachiya’ çeşidine ait ağaçlarda bilezik alma; kontrol, tek ve çift bilezik alma şeklinde uygulanmıştır. Tam verim çağındaki ağaçlarda bilezik alma uygulamaları tam çiçeklenme sonrası yapılmıştır. Çeşidin meyve verim ve bazı pomolojik özellikleri belirlenmiştir. Meyve ağırlığı, meyve çapı, meyve yüksekliği, meyve kabuk rengi (L, a, b), pH, titre edilebilir asitlik (TA) (%), meyve eti sertliği (kg / cm2) ve suda çözünebilir toplam kuru madde içeriği (TSS) belirlenmiştir. Araştırma Bulguları: En yüksek ağaç başına verim Kontrol (120.74 kg ağaç-1) uygulamasından elde edilmiştir. En iri meyveler 383.23 g değeri ile çift bilezik alma uygulamasından elde edilmiştir. Çift bilezik alma uygulaması meyve boyu ve meyve eni değerleri bakımından en yüksek değerleri oluşturmuştur (sırasıyla 79.22 mm, 94.71 mm). Suda çözünebilir toplam kuru madde içeriği bakımından uygulamalar arasında farklılık olduğu (p

Effects of different trunk girdlings on fruit yield and pomological characteristics of persimmon (Diospyros kaki L. cv. Hachiya)

Objective: This study was performed to determine the effects of two girdling practices on yield and some pomological properties of persimmon trees in 2019. Material and Methods: The gridling practices were applied to Hachia variety, common in Çanakkale, as single girdling, double girdling and control. Girdling treatments were performed after full blossom in full yield trees. Fruit yield and some pomological properties of the variety were determined. Fruit weight, fruit width, fruit size, fruit skin colour (L, a, b), pH, titratable acidity (TA) (%), fruit flesh firmness (kg / cm2) and total soluble solid content (TSS) were determined. Results: The highest yield per tree was obtained from the control (120.74 kg tree-1) treatment. The largest fruits with a value of 383.23 g were obtained from double girdling treatment. The double girdling application provided the highest values in terms of fruit length and fruit width (79.22 mm, 94.71 mm, respectively). There was a significant difference (p
