Abstract:
In order to study the flower bud differentiation of seedlings of peach,the twoyear-old seedlings of Prunus persica cv.Okubo were treated by some pieces of plant hormones by spraying or immersing buds on flower bud stage,the results showed that these treatments,KT30 spraying at 1mg/kg two times,PP333 immersing buds at 1000(mg/kg) two times,PP333 spraying at 2000mg/kg one time,PP333 immersing buds at 2000mg/kg two times,Eth spraying at(500mg/kg) two times,Eth immersing buds at 1000mg/kg one time,S3307 spraying at 125mg/kg two times,S3307 spraying at 250mg/kg two times have a significantly efficiency in declining the nodes of the earliest blooming buds,and these treatments,KT30 spraying at 1mg/kg two times,PP333 immersing buds at 1000mg/kg two times,PP333 spraying at 2 000mg/kg one time,Eth immersing buds at 1000mg/kg two times,S3307 immersing buds at 125mg/kg one time have remarkable efficiency on Flowering induction in second degree branches.
