Özet
Bu çalışmada; Ferro, RS841, Agentario ve Macis anaçları üzerinde aşılı yetiştirilen Crimson Tide karpuz çeşidinin sergen koşullarda 2009 -2010 yıllarında derim sonrası kalitesini belirlemek amaçlanmıştır. Aşılanmamış Crimson Tide çeşid i meyveleri kontrol olarak kullanılmıştır. Ülkemizde yaygın olarak kullanılan sergen koşullarında derimden sonra meyveler 27 ° C’de %50±5 oransal nem koşullarında 7 gün depolanmıştır. Meyve örneklerinde; meyve kabuk kalınlığı (mm), ağırlık kayıpları oranı (% ), suda çözünebilir toplam kuru madde içeriği ( SÇKM, %), meyve eti sertliği (MES, kg- k), titre edilebilir asitlik (TEA, %), meyve suyu pH’sı, meyve et rengi (L* a* b*) , mantarsal bozulmalar (%), fruktoz, g likoz, s akkaroz ve toplam şeker içerikleri (%) ile ? -karoten, toplam likopen ve toplam karotenoid içerikleri (µg/g ) ile meyvelerin tat durumunu belirlemek için duyusal analizler (1 -9) gibi fiziksel ve kimyasal parametrelerde meydana gelen değişimler incelenmiştir. Bulgularımıza göre, sergen koşullarda Crimson Tide karpuz çeşidinde mantarsal bozulma görülmemiştir. S ergen koşulunda aşılı ve aşısız Crimson Tide karpuz çeşidi meyvelerinde hakim şekerin sakkaroz (ortalama %3 .76 -5 .58) olduğu saptanmıştır. Ağırlık kayıpları, SÇKM, meyve et rengi a* ve b* değerleri ve sakkaroz içeriği artarken, meyve kabuk kalınlığı, MES, TEA, fruktoz, g likoz ve toplam şeker, toplam likopen ve toplam karotenoid içerikleri, meyve et rengi L* değeri ve duyusal tat azalmıştır.
The objective of this study is to determine the postharvest quality of Crimson Tide watermelon cultivar grafted on Ferro, RS841, Age ntario and Macis rootstocks in c ommon marketing condition in 2009 -2010 years. Ungrafted Crimson Tide cultivar was used as control. Fruits were also kept at 27 ° C and 50±5% relative humidity for 7 days which is a common marketing condition for watermelons in Turkey after harvest. Changes in physical and chemical parameters such as fruit rind thickness (mm), percent weight loss (%), total soluble solid content (TSS, %), fruit flesh firmness (FFF, kg- k), titratable acidity ( TA, %), pH, fruit flesh color (L* a* b*), incidence of fungal decay, fructose, g lucose, sucrose and total sugar contents (%) and β -carotene, total lycopene and total carotenoid contents (µg/g ) and s ensory evaluation for taste were determined immediately after harvest, after 7 days during the c ommon marketing condition . According to data, fungal disorders were not seen during the c ommon marketing condition. Sucrose (3.76 to 5.58% on average) of dominant sugar was determined in g rafted and ungrafted Crimson Tide watermelon cultivar during the c ommon marketing condition. Weight loss, TSS, a* and b* value of fruit flesh color and sucrose contents increased while rind thickness, FFF, TA, fructose, g lucose and total sugar, total lycopene and total carotenoid contents , L* value of fruit flesh color and sensory taste decreased during the c ommon marketing condition.
