摘　　要：以盛果期玉露香梨和龙宝梨为试材,研究了高光效开心树形整形修剪模式下枝组结果方式对梨果质量的影响。结果表明,不同枝组类型及枝轴长度对果个发育和品质的影响不同:枝组类型来看,短果枝果形指数低,斜果率高;而长果枝与之相反,果形指数达到了1.03,比短果枝提高了11.96%,果实综合质量较高。从枝轴长度来看,短枝轴果个较小,果形指数低,果肉可溶性固形物含量较低;而长枝轴与之相反,果个大小、果形指数、果品花色苷含量等果实质量指标与枝轴长度呈正相关(P<0.01)。17-18 years old pear tree of Yuluxiang and Longbao were used to study the appropriate length of fruit-bearing branch to increase the fruit quality of pear in open center tanning system. The results showed that： Fruit shape index decreased in the treatment of short fruit-beating branch, but oblique fruit index increased at same time. Meanwhile, fruit shape index increased by 11.9%, and reached 1.03 in the treatment of long fruit-bearing branch. Fruit weight, fruit shape index and soluble solids content decreased in the treatment of shorter fruit-bearing branch group. On the contrary, fruit weight, fruit shape index, soluble solids content and anthocyanin content in- creased in the treatment of longer fruit-bearing branch group, and appeared in a positive relation with the length of fruit-bearing branch （P〈 0.01）.
