Abstract:: Taking ‘Suili 3’ flower buds as test material，the HPLC method was used to study the changes of the endogenous hormones contents in flower buds at germination process of ‘Suili 3’.The results showed that the contents of IAA and ZT were overall raised，which indicated that the demand quantities of IAA and ZT were gradually increased in ‘Suili 3’ flower buds germination process.On April 28th ZT appeared low ebb，IAA in peak.On May 5th ZT appeared zooming，IAA in the low ebb，the change of the ZT and IAA were just opposite.The contents of the ABA and GA were declined in the flower buds germination process.And ABA decreased in large amplitude，while the GA declined but remained at a high level，and was higher than that of several other hormones significantly，which showed that demand high concentration of GA during ‘Suili 3’ flower buds germination process.
