Bor ve Çinko Uygulamalarının Nonpareil Badem Çeşidinde Bazı Kalite Özelliklerine ve Verimine Etkisinin Araştırılması

Abstract

Çiçek ve meyve dökümleri badem üreticilerin karşılaştığı önemli sorunlardan birisi olup, meyve tutumu özellikle badem ağaçları için çok önemlidir. Mikro besin elementlerinden bor ve çinkonun küçük meyve dökümlerinin yanı sıra meyve tutumu üzerine de önemli bir etkisi vardır. Bu çalışmada Ege Bölgesinde yetiştiriciliği yapılan Nonpareil badem çeşidine tam çiçeklenme döneminde bor (%0.175 H₃BO₃), çinko (%0.2 ZnSO₄) ve bu her iki mikro besin elementinin karışımı uygulanmıştır. Kontrol olarak seçilen ağaçlara ise sadece yayıcı yapıştırıcı ilave edilen su püskürtülmüştür. Bu uygulamaların Nonpareil badem çeşidinde bazı meyve fiziksel özelliklerine, meyvede makro-mikro element içeriğine ve ağaçların verimine etkisi araştırılmıştır. Uygulama yapılmayan bademlerde kabuklu meyvelerin en, boy, yükseklikleri, iç badem meyvelerin ağırlığı ve eni, B ve/veya Zn uygulaması yapılanlara göre daha yüksek, bulunmuştur. Bor ve çinko uygulamaları ile çift badem oranı kontrole göre düşmüş, verim değerlerine etkisi ise kontrol uygulamalarına göre daha yüksek bulunmuştur.

A Study on the Effects of Boron and Zinc Applications on Some Quality Properties and Yield in Nonpareil Almond Variety

Abstract

One of the greatest concerns of almond producers is the problem of flowers and fruit drop off the trees. Fruit set is very important especially for almond trees. Boron and zinc, which are micronutrients, have an important effect on minor fruit set, as well as fruit drop. In this study, boron (0.175% H₃BO₃), zinc (0.2% ZnSO₄) and mixture of these two micronutrients were applied in its full-flowering period to Nonpareil almond variety, which is cultivated in the Aegean region. Water containing only spreader adhesive was sprayed onto the trees selected as the control group. The investigation encompassed the effects of these applications on specific physical fruit properties, macro/micro nutrient element contents and yield of the trees in Nonpareil almond variety. The specific physical properties that were investigated were, width, length, weight of nut and kernel fruit and shell thickness of the harvested fruits. The width, length, height of nut fruits and the weight and width of kernel fruit were higher in B and/or Zn treated plants than in non-treated plants. With the boron and zinc applications, double ratio decreased compared to control, whereas the effect on yield values were found to be higher compared to that of control applications.
