Journal Title: International Journal of Farming and Allied Sciences - Year 2013, Vol 2, Issue 1
Abstract
With due attention to importance of citrus as one of the most important horticulture and exports crops of iran and in order to increasing of shelf life and quality improvement of citrus, research in this field is necessary, and the purpose in this study is improvement the Qualitative andquantitativecharacteristics of orange at storage via Polyamins application. This experiment was performed in factorial base on a completely randomized blocks design (CRBD) with three replications during 2010. Treatment included three levels of Spermidine (0, 1 and 1.5 mM) with control that use pure water and temperatures at two levels (2 and 4 °C) and incubation storage period at three levels (one, three and five weeks after harvest). The results indicated that the effect of Spermidine on chilling-injury, weight of single fruit, TA, flavor index (TSS/TA), fruit weight loss and TSS was significant. Effect of temperature on the mentioned characters (exceptional TA) was not significant. The effect of storage period on the percentage of fruit weight loss, vitamin C, TSS, TA, percentage of fruit juice and TSS/TA was significant. The best concentration in this experiment for reduce of chilling injury was spermidine 1.5 mM (Fi 1 & 2).
