AYDIN İLİ KUYUCAK İLÇESİNDE YETİŞTİRİLEN GÖBEKLİ PORTAKALLARIN MUHAFAZASI ÜZERİNE FARKLI MEYVE İRİLİGİ VE DERİM ZAMANLARININ ETKİSİ

Washington Navel and Frost Navel oranges grown in Aydin province Kuyucak district were harvested at three different size (small, medium, large) and time (22 November, 03 December, 10 December 2005), and were stored in two different storage houses (natural conditions for 6 months, cold storage for 4 months). Washington Navel and Frost Navel fruit stored in natural conditions had average weight loss % 29.32% and 25.85%, physiological and pathological disorder 37.78% and 40.00%, fruit juice 42.71 and 40.61, TSS 11.84 and 11.71, TA 0.64 and 0.59, TSS/TA 18.98 and 20.43, pH 3.83 and 3.92, respectively, at the 6th month. That of Washington Navel and Frost Navel fruit stored at cold storage (5±1°C) had average weight loss 12.79 % and 11.51 %, physiological and pathological disorder 66.30 % and 86.11 %, fruit juice 36.57 and 35.39, TSS 10.42 and 10.44, TA 0.79 and 0.82, TSS/TA 14.10 and 14.54, pH 3.50 and 3.65, respectively, at the 4th month. While fruit size increases and harvesting time delays, fruit weight loss decreases in both storage types. Fruit could be stored for 5 months in the natural conditions and 3 months in the cold storage without losing much quality. [ABSTRACT FROM AUTHOR]
