The effects of calcium chloride (CC), either singly or in combination with gibberellic acid (GA), 2,4-D and benomyl, on increasing peel resistance, delaying senescence and minimizing storage loss in satsuma mandarin cv. Owari were investigated. CC (2%) was applied 2 and 3 times on fruits grown in Turkey before harvest in 1998 and 1999, respectively. Fruits were analysed at harvest, and after 6 and 12 weeks of storage at 5 plus or minus 1 deg C and 85-90% RH. Greater fruit weight loss was noted in the first year than in the second year, with the greatest weight loss in the control recorded after 12 weeks in the second year. Greater weight loss was observed during the second than the first storage period, probably due to peel aging. In both years, the control fruits had better colour, while fruits treated with CC + 2,4-D + GA showed the least colour development. Similar results were obtained in treatments containing GA. Benomyl had a positive effect on colour development in both years. Significant increases in EC were noted during harvest and after 6 and 12 weeks of storage in 1998 and 1999 (36, 40 an 54% and 29, 39 and 62%, respectively). The highest EC value was recorded for CC + 2,4-D + benomyl. Fungal decay was not prevalent at the end of the storage period, indicating that the treatments significantly improved the storage quality of satsuma mandarin.
