Abstract: The cell numbers and sizes in fruits were investigated and changes of endogenous hormones and polyamines contents in fruits were studied during fruit development period in Red Fuji apple on different dwarfing interstocks (B9 , M26 and SH38 ). The results indicated that the cell numbers and sizes in fruits were influenced by different dwarfing interstocks types but the times of cell division had no change. The trends of endogenous hormones and polyamines contents were not affected by dwarfing interstocks. The changes of endogenous IAA, GA3 and Put contents on three types of dwarfing interstocks all showed a single peak curve. And the endogenous ZR and spd contents both kep t declining. During the most part of this period, the contents of endogenous hormones and polyamines on B9 and M26 were markedly higher than that on SH38.
