摘　　要：为选出适合尖把王梨的矮化中间砧,以克服尖把王梨幼树结果晚、丰产晚的缺点,研究了不同矮化中间砧对尖把王梨幼树的产量和树势的影响。结果表明:S2、S5、S6矮化中间砧对尖把王梨幼树均表现良好的早期丰产性和矮化性能,并且有矮化中间砧的尖把王梨幼树的总枝量、短枝量和短枝率均高于对照,有利于花芽形成和早期丰产。其中,S2致矮效果最好,可在我国梨树生产中推广应用。The effect of different dwarfing inter stocks on yield and tree vigor of young Jianbawang pear trees was studied to overcome the disadvantage of late fruit-bearing and late maturity.The results showed that the inter stocks of S2,S5 and S6 had good effects on its early high yield and dwarf property,and its total branch number,short branch number and short branch rate were all higher than CK,which is beneficial to flower bud formation and early high yield.S2 dwarfing inter stock with good dwarfing effect should be popularizedin pear production in China.
