Abstract: To definitude the flower sequence with higher fruit set and pollinator with higher rate of fruit without sepal, 12 pear cultivars as pollinators were used in this study. The work studied on the different pollinators effect on the different fruit set sequences and sepal persistence in Dangshansu pear by field experiment, which could provide technologic basis for Dangshansu pear product with high efficiency and fine quality. The results showed that rate of the fruit set was the highest at the third flower sequence and showed no significant difference in different position. The results of different pollinators showed Hongsucui was the highest rate with 70.30% and the lowest Zisu was only 25.24% with significant difference. At the rate of fruit without sepal, Xinshiji was the best pollinator, then Huangguan, and Chili was poorer.
