摘　　要：选择3个抗逆性强的梨品种高接于翠冠梨主、侧枝延长枝上，探讨高接抗逆性品种防控梨叶早衰脱落与花芽提早萌动的效果。结果表明：高接处理植株当年可使高接部位以下30～50 cm 纵向范围内叶片脱落延缓15～20 d ，抑制高接部位以下80～100 cm 纵向范围内花芽提早萌动，翌年开花数量、花朵坐果率及单株产量显著或极显著高于对照。本研究结果推广应用前景看好。Top-grafting pears with resistant varieties to prevent early defoliation and germination of the flower buds was studied . Three cultivars were chosen to graft onto limbs and branches of Cuiguan pear . The grafting postponed the leaf-falling 30 - 50 cm below the insertion point for 10 - 15 days . It also inhibited early germination of the flower buds located 80 - 100 cm below the insertion . Additionally ,the number of flowers ,fruiting rate and single plant yield of the pear a year after the top-grafting were all significantly more than the control . It was concluded that the top-grafting with the resistant varieties could be a means applied to deter the early defoliation and flower bud germinating for the pears .
