Abstract: The ten-year-old trees, Pyrus bretschneideri cv. ‘Dangshan Suli’, were used as materials to spray diff erent concentrations of sodium selenite fo r analyzing the effect of selenium on the mineral elements content and the storage properties of the pear fruits. The results showed: s praying selenium could increase the content of potassium, sulfur, iron, manganese, copper, boron and selenium. When spraying 5 mg·L-1 Se dosage, the content of iron increased significantly 21.30%（P＜0.01）, and the content of copper increased significant 24.60%（P＜0.05） comparing with the control. With the increase of the Se dosage, the content of iron and copper decreased gradually, but the content o f potassium, sulfur, manganese, boron and selenium increased gradually. The content o f sulfur and selenium increased significantly 72.68% and 64.29%（P＜0.01）, and the content of po- tassium, manganese and boron significant increased 13.78%, 19.82% and 26.15% respectively（P＜0.05） when spraying 20 mg·L-1 Se dosage. Ho wever, the content of phosphorus significant decre as ed 45.87% and 37.28% respectively when sp raying 5 and 10 mg·L-1 Se dosage（P＜0.05）. Spraying 5 mg·L-1 Se dosage could significant decrease the rate of fruit disease after the cold storage, and improve the storage properties of the pear fruits compared with the control. The Se dosage was significant positive co rrelation with the content of selenium, magnesium and bo ron（P＜0.05）. The content of iron was significantly negative correlation with the content of calcium and zinc（P＜0.01）, and it was significant negative correlation with the content of nitrogen（P＜0.05）. Therefore, the effect of Se on the mineral elements content and the storage properties varied depending on its dosage.
