Abstract

Yalova Atatürk Bahçe Kültürleri Merkez Araştırma Enstitüsünde iki yıl süreyle yürütülen bu çalışmada Yalova ve Bursa yörelerinde yetiştirilen Red Globe şeftali çeşidinin derim olumu, depolama süresi ve düşük saklama sıcaklıklarında meyvelerde gözlenen fizyolojik kökenli bozukluklar üzerinde çalışılmıştır. Meyvelerin derim olumlarının saptanmasında meyve iriliği, zemin rengi, meyve eti sertliği, suda çözünür kuru madde içerikleri, meyve eti sertliği ile suda çözünür kuru madde kombinasyonu, olgunlaşma süresi, titre edilebilir toplam asitlik ve solunum klimakteriği üzerinde çalışılmış ve incelenen bu olgunluk ölçütleri içinde uygulama bakımından en güvenli olanının suda çözünür kuru madde içerikleri ile meyve eti sertliği kombinasyonu olduğu sonucuna varılmıştır. Yapılan depolama testleriyle Red Globe çeşidinin oldukça dayanıksız bir şeftali olduğu belirlenmiş ve depolamayı sınırlayan en önemli etmenler özde bir fizyolojik bozukluk olan iç bozulması ile ağırlık kayıpları olmuştur.

Studies on Postharvest Physiology of Some Important Peach Cultivars-1 (Red Globe)

Abstract

Two years of studies conducted at Yalova Horticultural Research Institute on Red Globe variety grown in Yalova and Bursa regions involved postharvest characteristics of the variety from the point of harvest, ripening and storage potentials. Among such parameters as fruit size, ground color flesh firmness, soluble solids, combination of flesh firmness and soluble solids, ripening period, titretable acidity and respiratory climacteric, the most reliable method on the determination of harvest maturity was found to be the combination of flesh firmness and soluble solids. Storage experiments indicated that Red Globe is not a long-storing peach variety and the most important factors limiting storage period are weight loss and the physiological disorder called "mealy breakdown".
