    Armut fidanı üretiminde farklı çeşit/anaç kombinasyonlarının bazı fidan özelliklerine etkisi
    (2018) Çetinbaş, Melike; Butar, Sinan; Sesli, Yılmaz; Yaman, Burcu
    Bu çalışma, armut fidanı üretiminde farklı özelliklere sahip çeşit ve anaçların fidan gelişimi üzerine etkilerini belirlemek amacıyla 2014 ve2015 yıllarında yürütülmüştür. Çalışmada, Deveci ve Santa Maria armut çeşitleri ile Quince C, Fox9, OHxF40, Fox11, OHxF87, OHxF97, OHxF69, OHxF 333, BA 29 anaçları kullanılmıştır. Çeşitler ve anaçlar T göz aşısı yöntemiyle 10 Eylül 2014 tarihinde sera ortamında aşılanmıştır. Aşılamadan 18 ay sonra çeşit/anaç kombinasyonlarının fidangelişimini belirleyebilmek için, anaç çapı (mm), fidan çapı (mm), fidan boyu (cm), sürgün sayısı (adet), ortalamasürgün uzunluğu (cm), ortalama sürgün çapı (mm) ve anacın dip sürgünü oluşturma durumu (adet) incelenmiştir. Çeşit/anaç kombinasyonlarında fidan boyu ve anaç çapına anaçlar ve çeşitler ayrı ayrı etki göstermiştir. En kısa fidanlar Fox11 (104.01 cm) anacından ve Deveci (126.83 cm) çeşidinden elde edilmiştir. Anaç çapı en az olan anaç Fox9 (15.54 mm), çeşit ise Santa Maria (17.83 mm) olarak belirlenmiştir. Fidan çapına ve sürgün sayısına çeşit x anaç interaksiyonunun etkili olduğu bulunmuş ve Santa Maria/Fox11 kombinasyonundan fidan çapı (11.71 mm) ve sürgün sayısı (3.28 adet) en az olan fidanlar elde edilmiştir.Çalışmada kullanılan armut anaçlarınıngelişme kuvvetlerinin tespiti ve değerlendirilmesi önemli olup, çalışmanın bundan sonra yapılacak çalışmalara bilimselnitelikte ışık tutacağı düşünülmektedir.

    Effects of different dosages of ReTain (aminoethoxyvinylglycine) on pre-harvest fruit drop and fruit quality of ‘Golden delicious’ apple.
    (Einfluss unterschiedlicher ReTain-Dosierungen (Aminoethoxyvinylglycine) auf den Vorerntefruchtfall und die Fruchtqualität bei der Apfelsorte ‘Golden Delicious’, 2022) Çetinbaş, Melike; Butar, Sinan; Sesli, Yılmaz
    The study was carried out to reduce the losses due to the yield-fruit quality caused by the pre-harvest fruit drop problem of the ‘Golden Delicious’ variety. To increase the profitability of the producer in the orchards established with this variety, the effects of ReTain, a human and environmentally friendly commercial product that can be used in practical application, in different dosages on pre-harvest fruit drop, and fruit quality were examined. The study was conducted in the ‘Golden Delicious’ apple orchard grown in two different locations (Egirdir and Civril) between 2016 and 2017. ReTain’s dosages of 830 g/ha, 700 g/ha, 550 g/ha, 400 g/ha were applied to fruits and leaves 4 weeks before the estimated harvest. Water + Tween 20 (surfactant) were sprayed to control trees. In both locations, all ReTain applications had significantly reduced pre-harvest fruit drop. It also increased the fruit size and weight. As a result, considering both fruit loss and fruit quality; the most suitable practical application for the ‘Golden Delicious’ apple variety was determined to be ReTain 830 g/ha 4 weeks before the estimated harvest.

    The effects of pre-harvest prohydrojasmon application on yield and fruit quality of 'starking delicious' apples in different locations
    (Parlar Scientific Publications (PSP), 2018) Çetinbaş, Melike; Butar, Sinan; Sesli, Yılmaz; Sekmen, Şafak; Yaman, Burcu
    'Starking Delicious' apple variety is cultivated extensively in Turkey and specifically at the IspartaEgirdir and Denizli-civril regions. Sometimes, fruit peel color is not attractive in this cultivar leading to low market value. Hence, the primary aim of this research was to improve the fruit peel color of 'Starking Delicious' apples. For this purpose, different dosages (0, 100, 150 and 200 ppm) of Prohydrojasmon were applied to 21 days before anticipated harvest sprays and following that after 7 days sprays for apples in two locations (Egirdir-civril). In this study, yield (kg/tree), pre-harvest drop (%) and some fruit quality parameters [fruit width (mm), fruit length (mm), fruit weight (g), fruit flesh firmness (N), solible solids content (SSC, %), titratable acidity (TA, %), fruit peel color (L*, a*, b*, C*, h degrees) were assessed for per treatments. Prohydrojasmon applications, especially in the fruit of the fruit color expressing redness a* value was determined to be increase. In this application which is especially examined fruit peel color formation, a* value and C* values (determine of concentration of a values) are found the most in 150 and 200 ppm Prohydrojasmon application. It is believed that without any negative effect both in fruit yield, pre-harvest drop and fruit size, fruit flesh firmness, using 150 or 200 ppm of Prohydrojasmon which has positive effect on fruit peel color can be proper in Egirdir and civril locations.
