Abstract:: The experiment used the pollinated method on the fifteen-year-old ‘Nanhong’ pear,which was top grafted was used as material，hand-pollinate method was adopted to study the effects of pollinators on the fruit setting rate，calyx-abscission rate,fruit shape index,fruit firmness,solible solid content and acid-sugar ratio in order to choose the suitable pollinating cultivar and supply the reference bases for increasing yield and improving cultivation.The results showed that 10 pollinators performed well compatibility with over 70% fruit setting rate.Seven cultviars had less 10% calyx-abscission rate.Average fruit weight increased significantly which was pollinated by ‘Huagai’ pear，28.11% highter than control.Fruit shape index showed decreaseing trend with all pollinators excluding ‘Huagai’ pear.Fruit firmness and single fruit weight increased obviously pollinated by ‘Pinguo’ pear and ‘Huagai’ pear.There was no significant difference on solible solid content and acid-sugar ratio among different pollinators.‘Pingguo’ pear and ‘Huagai’ pear were the best pollinators for ‘Nanhong’ pear for this study.
