Abstract: The change of mineral element contents in fruit bagged was observed, and its relationship withbrowning spot of Huangguan pear was explored as well. The resulted showed that: the trends of K, Ca, Mg, Fe, Cu,Zn, Mn changes of the fruits of covered three layers bag and white bag were similarly with without bag fruits. For thefruit of 80 days after flowering, the content of K, Mg and Fe in covered three layers bag were significantly higher, butthe Ca was lower than without bag fruits. The Ca content in the white bag was lower than which in the without bagfruits. Moreover, the ratios of Ca /K, Ca /Mg and Ca /( Mg + K) in covered three layers bag were significantly lowerthan the without bag fruits. The content of Cu and Mn was highest in the fruit from white bag, followed by three layers bag and without bag fruits. The content of Zn in the fruit peel 80 - 90 days after flowering was no differencecompared between three layers bag and without bag, but which from three layers bag was significantly lower than thefruit from white bag 100 days after flowering. The contents of Ca decreasing and K, Mg increasing is closely relatedto the generation of speckles in the surface of Huangguan pear.
