Özet:

 In the present study, the effects of some postharvest treatments on fruit quality of Golden Delicious apple variety during storage were investigated. The apples, harvested at the optimal maturity stage, were immediately transported to the laboratory. Fruit, which have the shape, size and color specific to the variety, were divided into 4 groups for auxin 20 mg L-1, NPA 1 µg L-1, NPA 1 µg L-1 1-MCP 0.625 ppm and control treatments. For auxin, NPA and control treatments apples were immersed into water containing Tween-20 as a surfactant during 3 min. For NPA1-MCP treatment, apples were subjected to 0.625 ppm 1-MCP application at room conditions for 12 h after dipping. Dried apples were packaged in plastic boxes and stored at 0 ºC at 9095  relative humidity for 6 months. Weight loss, solible solids content, titratable acidity, fruit skin color, respiration rate, decay rate, physiological disorders and sensory quality were determined during cold storage. For shelf life studies, the same analyses were repeated by keeping the apples at 20 ºC and 605  relative humidity for 7 days after cold storage. The best result was obtained from NPA1-MCP treatment in terms of fruit quality during both cold storage and shelf life in Golden Delicious apple variety. Weight loss, titratable acidity and respiration rate during storage were less in apples treated with NPA1-MCP compared to other treatments. It was concluded that Golden Delicious apple variety, harvested at optimal stage and treated with NPA1-MCP, can be stored for 6 months at 0 ºC at 9095  relative humidity. However, considering the 7-day shelf life period, it is recommended to limit the cold storage period to 5 months.

 Çalışmada, Golden Delicious elma çeşidinde derim sonrası bazı uygulamaların depolama süresince meyve kalitesi üzerine etkisi araştırılmıştır. Optimum derim zamanında derilen elmalar hızlı bir şekilde laboratuvara getirilmiştir. Çeşide özgü şekil, irilik ve boya sahip olan elmalar oksin 20 mg L-1, 1-N-naphthylphthalamic asit NPA, 1 µg L-1, NPA 1 µg L-1 1-Metilsiklopropen 1-MCP, 0.625 ppm ve kontrol uygulamaları yapılmak üzere 4 gruba ayrılmıştır. Oksin, NPA ve kontrol uygulamaları için kullanılan çözeltilere yayıcı yapıştırıcı olarak Tween-20 ilave edilmiştir ve meyveler çözeltilere 3 dakika daldırılmıştır. NPA1-MCP uygulaması için elmalar daldırma işleminden sonra 12 saat süre ile oda koşullarında 0.625 ppm 1-MCP uygulamasına tabii tutulmuştur. Üzerindeki su uzaklaştırılmış elmalar plastik kasalara yerleştirilerek 0 ºC ve  9095 oransal nemde 6 ay boyunca depolanmıştır. Depolama boyunca elmalarda ağırlık kaybı, suda çözünebilir kuru madde SÇKM miktarı, titre edilebilir asitlik TEA miktarı, kabuk rengi, solunum hızı, patojen ve fizyolojik kaynaklı bozulmalar ve duyusal kalite değişimi belirlenmiştir. Raf ömrü çalışmaları için soğukta muhafazadan çıkartılan elmalar 7 gün boyunca 20 ºC ve  605 oransal nemde bekletilerek aynı analizler yinelenmiştir. Golden Delicious elma çeşidinde hem soğukta muhafaza hem de raf ömrü sürecinde kalitenin korunması bakımından en iyi sonuç NPA1-MCP uygulamasından elde edilmiştir. NPA1-MCP uygulaması yapılan elmalarda depolama boyunca ağırlık kaybı, titre edilebilir asitlik ve solonum hızı diğer uygulamalara göre daha az olmuştur. Optimum dönemde derilerek NPA1-MCP uygulaması yapılan Golden Delicious elma çeşidinin belirtilen koşullarda 6 ay süreyle soğukta depolanabileceği sonucuna varılmıştır. Ancak 7 günlük raf ömrü süreci dikkate alındığında soğukta depolama süresinin 5 ay ile sınırlandırılması önerilmektedir.
