Effects of warm solutions of thiabendazole and packaging on qualitative and quantitative characteristics of Quince cv.Gorton(l)

This research was conducted in Khorasan Agriculture and Natural Resources Research center in 2002 with the main purpose of study the effect of fungicide (Thiabendazole) and packaging on storage life of quince fruits cv. "Gorton". The fruits after picking and grading, were dipped in fungicide solutions with different concentrations(0, 1000 and 3000 ppm) and different temperatures(25,40 and 45 centigrade degrees). Then the treatments were dried in room temperatures and packed in two packaging type (polyethylene bag with hole , polyethylene bag without hole) and transferred to cold storage (temperature 1 centigrade degrees, relative humidity 85%).Sampling were done after harvest and after 30, 60, 90, 120 and 150 days keeping of fruits in cold storage and qualitative atributes consisting (flesh firmness, water soluble solids, acidity, pH, weight loss, decay) were registered. The statistical design was 4 factors factorial adopted completely randomized design with 3 replicate. The results showed that fungicide (Thiabendazole)(1000 ppm,40 centigrade degrees) and packaging in bags without holes reduced decay and maintained qualitative characteristics of quince in cold storage.
