SUMMARYThe effects of temperature, wax emulsion coating, hormone treatment, and their combination on the storage behavior of Nagpur and Darjeeling mandarins were investigated. Use of 2,4‐D with wax coating was more effective in prolonging the storage life of both varieties at any storage temperature than either wax coating or 2,4‐D used separately. The storage lives of Nagpur and Darjeeling oranges were respectively 50 and 35 days at normal temperature (50–85°F) and 90 and 75 days at 40 ± 1°F when treated with 2,4‐D (1000 ppm for Nagpur and 2000 ppm for Darjeeling varieties) followed by wax coating. Wax‐coated Nagpur and Darjeeling oranges were in a good marketable condition for 30 and 22 days, respectively, at room temperature, whereas the respective controls remained marketable for only 10 and 7 days. At 40 ± 1°F, storage lives were respectively 60 and 52 days for Nagpur and Darjeeling oranges coated with wax, and 40 and 25 days for their respective controls. Hormone‐treated fruits, like the controls, lost their marketable appearance through considerable desiccation, pitting, and shriveling. Loss in weight and spoilage due to fungal attack and rind blemishes were least in fruits treated with 2,4‐D followed by wax coating in both varieties and each storage temperature. Pulp‐to‐peel ratio, reducing sugar, sucrose, total sugar, sugar‐to‐acid ratio, pH value, and specific gravity in juice increased, whereas vitamin C content and titratable acidity decreased, during storage in all treatments. No off flavor was produced in any case.
