Abstract:
In order to explore the growth potential regulation pathway of pear tree，selecting the standard tree and dwarfed tree as the test materials.The difference in the growth，hormonal metabolism and interactions between standard tree and dwarfed tree were investigated.The results showed that there was difference in the growth between standard tree and dwarfed tree，the dwarfed tree only a growth peak in the whole growing season；the intergraft of two types had certain effect to the shoots growth；the period of growth，the standard and dwarfed tree treated by BPA and GA3 treatment promoted growth of shoots；in addition，the NPA treatment could significantly reduce the growth of standard tree and dwarfed tree.The results showed that the pear tree growth potential was regulated by the endogenous hormones，the NPA had a modified for pear tree growth potential.
