Abstract:: The healthy and diseased fruits of Korla fragrant pear after cold storage were used as materials，and the atomic absorption spectrophotometry mehod was applied to compare the different on the contents of Ca，Mg，K with various parts at two kinds fruits,in order to explore the etiology of this disease.The results showed that the contents of Ca，Mg，K were different in various tissues.It was much lower on Ca content of peel and flesh in diseased fruits，and also lower on Mg，K content of upper tissue than that of health ones，but this different on Mg，K content was smaller than that of Ca content.Thus，the top rot could be related to deficiency of Ca in peel and flesh and lower Mg in upper peel in Korla fragrant pear.
