1985 ve 1986 yıllarında Yalova’da yapılan bu çalışmada Dixired ve J.H. Hale şeftali çeşitlerinde paclobutrazolun (PP-333) vejetatif gelişme ve bazı meyve özelliklerine etkisi incelenmiştir. Uygulamalar 750 ve 1000 ppm dozlarında petal yaprakların dökümünden 3 hafta sonra yapılmıştır. Her iki çeşitte de 750 ve 1000 ppm’lik dozlar sürgün boyunun kısalmasına neden olmuştur. Sürgün boyundaki azalma çeşitlere göre doza bağlı olarak %10 ile %25 dolayında olmuştur. Meyve gözü sayısında doza bağlı olarak %24 dolayında artış saptanmıştır. Boğum uzunluğu ise kontrole göre ortalama 0.06-0.16 cm arasında kısalmıştır. Paclobutrazol uygulaması yapılmış meyvelerde kısmi meyve eti sertliği azalması, suda eriyebilir kuru madde artışı saptanmıştır. Bu farklılık, şeftali çeşitlerinde hasat olumunu 5-7 gün erkene alabilecek düzeydedir. Her iki çeşitte de PP-333 uygulamalarında meyve büyüklüğü ve meyve ağırlığında görülen artışlar kümülatif bir verim artışının olduğunu göstermektedir.

Two years of studies starting in 1985, have been conducted to investigate the effects of paclobutrazol (PP-333) on vegetative growth and fruit quality of Dixired and J.H. Hale peach cvs. grown in Yalova. PP-333 was applied three weeks after petal fall with concentrations of 0.750 and 1000 ppm. The applications resulted in a reduced shoot length of about 10-15 %according to cultivars and doses. Number of flower buds increased about 24%. Slightly decrease in fruit firmness and increase in soluble solids were obtained due to PP-333 applications and also the loss of green colour were observed on treated trees. PP-333 applications hastened the maturity by 5-7 days compared to control. The increased yield of these cvs. appeared to be a composite of increased fruit size and fruit weight at harvest.
