Abstract：The Yishui Red Fuji apple tree with different dwarfing interstocks including M26,SH6,Qingzhen 2,Liaozhen 2 and M9T337 were used to investigate the tree growth,fruit yield and quality,and hormone content in lateral buds at flower bud differentiation stage from 2015 to 2017.The results showed that the shoot growth of Yishui Red Fuji trees grafted on SH6 was significantly higher than that on the other four interstocks,although the shoot growth tendency was similar with different interstoeks.The ratio of short shoots was the high-est (65.2％)and the proportion of long branches was the smallest (11.1％) when with M9T337 dwarfing interstock.The yield per plant was higher with M26 interstock.There was no significant difference in the average single fruit weight,fruit shape,fruit hardness,the content of soluble solid and titratable acid between the trees with the five different dwarfing interstocks.The endogenous IAA and GA3 decreased,while ZR and ABA eontents increased in lateral buds at flower bud differentiation stage.The IAA content was significantly different between the trees with different interstocks.The ratios of ZR to GA3 and ZR to IAA were higher and stable in the whole bud differentiation process,and those of trees with Liaozhen 2 interstock were higher compared to the other interstocks.
