DEVECİ ARMUDUNDA MEYVE MİNERAL MADDE İÇERİKLERİNİN ÖZ SULANMASI SORUNU İLE İLİŞKİLERİ

Öz sulanması elma ve armutlarda görülen ve büyük zararlar veren önemli bir fizyolojik bozukluktur. Çoğunlukla elmalarda görülen bir bozukluk olmasına rağmen hassas armut çeşitlerinde de önemli sorunlar oluşturabilmektedir. Bu çalışma ile Bursa yöresinde Deveci çeşidi ile kurulmuş armut bahçelerinde öz sulanması görülen meyvelerin mineral madde içeriklerinin incelenmesi amaçlanmıştır. Bu amaçla seçilen bahçelerden sağlıklı ve sorunlu meyve örnekleri alınmıştır. Bu örneklerde fosfor, potasyum, kalsiyum, magnezyum, demir, mangan, çinko, bakır ve bor analizleri yapılmış ve sonuçlar karşılaştırılmıştır. Elde edilen sonuçlara göre fosfor, potasyum, demir, çinko ve bakır değerleri arasında sorunlu ve sağlam meyveler açısından herhangi bir farklılık bulunamamıştır. Bununla birlikte sorunun görülmediği meyve örneklerinden belirlenen kalsiyum, magnezyum, mangan ve bor değerlerinin öz sulanması sorunu olan meyvelere oranla daha yüksek olduğu tespit edilmiştir. Bu elementler içerisinde kalsiyumda ortaya çıkan farklılık, diğer elementlere göre oldukça yüksek oranda bulunmuştur.

THE RELATIONSHIP BETWEEN THE MINERAL CONTENT OF FRUIT AND THE WATERCORE PROBLEM IN DEVECI PEAR

Watercore is an important physiological disorder affecting apples and pears. Although it is a disorder that mostly seen in apples, it can also cause serious problems in sensitive pear varieties. In this study, it was aimed to determine the mineral matter content of the fruit having watercore problem in the pear orchards established with Deveci cultivar in Bursa region. For this purpose, healthy and damaged fruit samples were taken from selected orchards. Phosphorus, potassium, calcium, magnesium, iron, manganese, zinc, copper and boron were analyzed in these samples and the results were compared. According to the results obtained, there was no difference between the values of phosphorus, potassium, iron, zinc and copper in terms of disordered and healthy fruits. However, calcium, magnesium, manganese and boron values obtained from healthy fruit samples were found to be higher than those with watercore problems. The difference in calcium was found to be quite higher than the other elements.
