    Farklı kiraz çeşitlerine uygulanan bazı büyümeyi düzenleyici maddelerin çiçeklenme ve meyve tutumu üzerine etkileri
    (Çanakkale Onsekiz Mart Üniversitesi, 2014) Duran, Fatmanur Uslu; Engin, Hakan
    Araştırma 2012 ve 2013 yıllarında Çanakkale ili Lâpseki ilçesindeki kiraz bahçesinde yürütülmüştür. Çalışmada Ma x Ma 14 anacı üzerine aşılı Summit, 0900 Ziraat ve Regina kiraz çeşitleri kullanılmıştır. Ölçümler için her ağaçtan birbiriyle yaklaşık aynı uzunluk ve formda üçer adet dal seçilmiştir. Her iki araştırma yılında da belirlenen aynı ağaçlara tam çiçeklenme ve tomurcukların kabardığı dönemde, bitki büyüme düzenleyicilerden olan Gibberellik asit (GA3) 25, 50, 100 ppm, Brassinosteroid (BR) 0.05, 0.1, 0.5 ppm ve 100 ppm GA3 + 0.1 ppm BR karışımı el pülverizatörü kullanılarak uygulanmıştır. Tomurcukların kabardığı dönemden, meyve olgunlaşma dönemine kadar araştırmaya ait tüm gözlemler 0900 Ziraat, Regina ve Summit kiraz çeşitlerinde kaydedilmiş ayrıca tomurcuk başına düşen çiçek sayısı ile birinci ve ikinci dönem meyve tutumu oranları tespit edilmiştir. Lâpseki yöresinde her üç kiraz çeşit için de çiçeklenme zamanları 2012 ve 2013 yıllarında paralellik göstermiştir. Her iki yılda da çiçeklenme Nisan ayı başında sırasıyla Summit, 0900 Ziraat ve Regina çeşitlerinde saptanmıştır. 2013 yılında tomurcuk başına düşen çiçek miktarı oranını, 0.5 ppm BR uygulaması, % 29 oranında arttırmıştır. Ayrıca 2013 yılında bütün BR uygulamaları olgunlaşma dönemindeki meyve tutum oranlarına olumlu katkı sağlamıştır. Birinci dönem meyve tutumunu 50 ve 100 ppm'lik GA3 uygulamaları arttırmıştır. Fakat bu etki ikinci dönem meyve tutumunda yapılan sayımlarda belirlenememiştir.

    ROLE OF 22S, 23S-HOMOBRASSINOLIDE AND GA3 ON FRUIT QUALITY OF '0900 ZIRAAT' SWEET CHERRY AND PHYSIOLOGICAL DISORDERS
    (Wydawnictwo Akad Rolniczej W Lublinie, 2015) Engin, Hakan; Gokbayrak, Zeliha; Sakaldas, Mustafa; Duran, Fatmanur Uslu
    Acquiring high quality in sweet cherry production is of great importance. Plant growth regulators have been used to increase yield and quality in the production of sweet cherries. Brassinosteroids, a relatively new group of plant growth regulators, have been found with interesting results on plant growth and development. This research was carried out to evaluate the role of brassinosteroids and gibberellins in development of fruit quality and occurrence of physiological disorders in '0900 Ziraat' sweet cherry. Gibberellic acid (GA(3)) and 22S, 23S-homobrassinolide were applied with a sprayer at full bloom and at the beginning of fruit development for a 2-year period. GA(3) was applied in concentrations of 25, 50, and 100 mg l(-1) and 22S, 23S-homobrassinolide was applied in concentrations of 0.05, 0.1, and 0.5 mg l(-1). A combined application of 100 mg l(-1) GA3 + 0.1 mg l(-1) 22S, 23S-homobrassinolide was also applied. Plant growth regulator applications mainly caused an increase in fruit weight and flesh to seed ration, and a decrease in fruit length. The effect was mainly due to gibberellin. Both Total soluble solids and titratable acidity were affected by the hormones and the seasons. Neither growth regulators had an influence on occurrence of the physiological disorders. They were at a lesser level in the second seasons.
