The combining treatments(CT)of Mandarin by low-dose irradiation and fruit fresh-keeping liquids reduce the rot or lose rate of the fruit,maintain fruit quality and fresh appearence and prolong the storage life.The results of a small scale experiment showed that after 140 days' storage at room temperature,the lose rate of Satsuma mandarin (Citrus unshin) treated with irradiation(60Co,3 krad) + SM,or irradiation(60Co,3 krad) +Jing-2B,was 12.9% and 8.0% lower than that of singly treated with SM1 of Jing-2B,respectively,and was 19.3% and 15.6% lower than that of singly irradiated.The result of a medium scale experiment showed that the combining treatment was also effective on long term preservation of Satsuma mandarin and Ponkan orange(C.poonensis).After 125 days' storage,the lose rate of Satsuma mandarin treated with CT method (60Co,3 krad + Jing-2B ) was 20.6%,which was 5.4% lower than that of treated with Thioponate pesticide.After 140 days' storage,the lose rate of Ponkan orange treated by CT method(60Co,3 krad + Jing-2B ) was 17,9%.which was 7.6% lower than that of treated with Thioponate pesticide.The analyescs of main nutricnsts indicated that CT method didn't exert any obvious influence on total sugar,total acid,vitamin C and amino acid content in the fruit.The method was also cheap and easy to utilize and might be a promising method in mandarin preservation.
