摘要： 为明确砀山酥梨较高的坐果花朵序位和脱萼率高的授粉品种，以12个不同梨品种为授粉品种，通过田间试验，研究了不同品种授粉对砀山酥梨不同花朵序位坐果率、花萼宿存的影响，为砀山酥梨优质高效生产提供技术依据。试验结果表明：不同序位花朵以第3序位坐果率最高；不同方位花朵坐果率无显著差异。不同授粉品种试验结果，红酥脆授粉坐果率最高，达70.30%；紫酥授粉坐果率最低，为25.24%，不同品种授粉坐果率差异达显著水平。不同品种授粉，果实脱萼率以新世纪为最高，黄冠次之，茌梨最低。

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.
